DIMENSION DATA

Lubrite Bushings and Bearings are made to suit individual requirements or practice. Lubrite products are finished to size and are ready for assembly without further machine work. Reaming for clearance or alignment will reduce their efficiency and operating life.

The following proportions are recommended:

DIAMETER

LENGTH

Bushings of least diameter consistent with shaft strength and stiffness give the highest mechanical efficiency. Where pressures require that bearing area be increased, change the length rather than diameter for a minimum loss of power by friction.

If possible, the length of the bushing should not be less than one and one-half times shaft diameter. Although a greater ratio of length to diameter is desirable, in certain applications such as hoisting sheaves, it is impossible to obtain this ratio. Lubrite bushings are in successful operation in many such places.

THICKNESS In general, the thickness of the wall should be at least 10 % of the inside diameter. In diameters under two inches, however, it is necessary to use relatively thicker walls in order to have sufficient metal to provide suitable lubricating recesses economically.

We recommend the following minimum wall thicknesses for either one-piece or two piece bushings.

STANDARD WALL THICKNESSES

I.D. OF BUSHING WALL THICKNESS

under 1/2" 1/8" l/2"-13/16" 5/32" 7 /8"-1-1/4" 3/16" 1-5/16"-l-5/8" 7/32" 1-11/16"-2" 1/4" 2-1/16"-2-5/8" 9/3,2" 2-11/16"-3" 5/16"

Over 1-1/4" I.D. the wall thickness can be figured by:

or

I.D. + 1/8" ( to nearest 1/32")

O.D. = 1-1/8 x I.D. + 1/4" (to nearest 1/16")

These proportions provide ample strength and proper quantity of lubricant for satisfactory results.

Naturally, other wall thicknesses can be provided. However, an extremely thin wall for the size of bushing is not recommended.

In FLANGED BUSHINGS, the thickness of the flange is ordinarily the same as the thickness of the wall of the bushing.

THRUST WASHER thickness should run from a minimum of 1/8" for small diameters up to 1/2" or more for large diameters. A rough formula is:

THICKNESS = O.D.

For washers up to 18" outside diameter a thickness of 1/2" will usually be sufficient.

l

SPEEDS AND LOADS

Lubrite Bushings are designed primarily for medium and heavy loads and slow and medium speeds.

They are not recommended for shaft surface speeds over 500 feet per minute, at conservative loads.

For ordinary service, bearing pressures equal to those customarily used for oil bushings are well within the capacity of Lubrite. For bushings requiring the greater load carrying capacity of Lubrite, the following factors are suggested and are well within the limits of successful Lubrite operation.

P = Bearing Pressure in pounds per square inch of Projected Bearing Area.

p = Total Load on Bearing (pounds) Bearing Length (inches) x Shaft Diameter (inches)

V = Shaft Surface Speed in Feet per Minute

V = 0.262 x r.p.m. x Shaft Diameter (inches)

PV The product of Actual Speed (V) x Unit Loading (P) should not exceed Average Factor

P :x V = PV (maximum)

Bearings should not be shortened in design simply because the resulting area will bring the product of load and speed within a particular factor, for the lower the pressure, the longer the service life.

The choice of an actual factor to be us-ed in design work is a matter of judgment and experience. Three representative groups are suggested. They do not represent ultimate limits, but are intended as a guide to bearing proportions which will give long, efficient service. Where conditions necessitate a factor greater than 70,000, speeds exceeding 500 feet per minute, pressures greater than 3,500 pounds per projected square inch, or other oonsiderations that may affect the operation of.the bearings - consult our engineers. Their experience is at your disposal and their recommendations place you under no obligation.

See Page 3 for proper material selecition to s?Jit 1,rri# PWririg WJJ$4ure for your appliootion.

MATERIALS AND BEARING VALUES

Lubrite Bushings and Washers may be made with practically any bearing metal to meet the conditions of the application. However, continued tests, experiments, and actual reports from Lubrite installations have enabled us to determine that of all the bearing metals tested, the following have proven the most successful with Lubrite lubrication and will meet the requirements of most applications.

GENERAL DUTY- for unit loadings up to approximately 1200 psi.*

STANDARD LUBRITE BRONZE ALLOY

ONE AND TWO PIECE BUSHINGS

We highly recommend for most applications, our Standard Lubrite Bronze Alloy which was developed in our own Laboratory and Foundry. You will find that this is the most economical high-grade bearing metal for Lubrite lubrication.

The approximate physical and chemical properties are as follows:

Our foundry is completely equipped to produce quality castings for Lubrite Bushings to practically any Bronze Alloy Specification,. upon request. However, the above alloys have proven to be very successful and will meet the conditions of most applications.

For unusual applications, Lubrite Bushings have been made from Monel metal, cast iron, stainless steel, Meehanite, Ductile Ni-Resist Cast Iron and Others.

*This loading is conservative and provides ample factor of safety for long service. It is used with equal success up to 2000 psi for slow-moving and static loads.

**For extremely heavy '!"'nit lo<:ds,. beyond th~ ~apacity of o~h.er bearings, w~ suggest our One Piece Bridge Bearing Bronze Lubrite Bushings with internal ,drilling and Lubriting. These bushings provide extremely high load-carrying capa<:i,tY. and provide high factor of safety for applications where extra long life is a must. Please present your application to our Engineers for their advice regarding higher loadings. No obligation, of course.

tThe change of grade of alloy is necessary for two-piece bushings in order to properly manufacture.

CLEARANCES AND TOLERANCES

The Lubrite lubrica~ing filII1; is considerably thicker than an oil or grease film, therefore, for a running fit, gre~ter de?rance 1s r~qmred .between bushing and shaft than for oiled bushings. In order to receive maximum life and service Lubrite self-lubricating bushings should not be reamed on assembly.

STANDARD CLEARANCES

( Running Fit)

Clearance Shaft Sizes (Over Nominal Shaft Size)*

3/8" - l" 1-1/16" - 1-3/8" 1-7 /16" - 1-15/16" 2" - 2-1/2" 2-9/16" - Z-15/16" 3" - 4" 4" - 5" 5" - Up

SPECIAL CLEARANCES

Special applications require larger running clear ances because of the nature of the operation. A Coarse Running Fit should be used for high ~ temperature applications, for sheave bushings, hydro-electric gate rollers and other similar oper ating conditions.

If ,, It is customary that the shaft size be made to the nominal fractional dimension, i.e.; for a 1-1/2" D shaft, the decimal dimension of the shaft is assumed to be: 1.500 ±·.881 (.001 beyond, either way). If a 1-1/2" I. D.

bushing is ordered, we automatically provide the bushing with the proper clearance, i. e., 1.506 ~:886 I.D. as obtained from the table of standard clearances.

The above listed clearances are our standard. If other clearances are necessary or the shaft is not to the nominal fractional size, we have a wide range of completed tooling to take care of the majority of possibilities.

The press fit is also assumed to be to the nominal fractional dimension, i. e., for a 1-15/16" O. D.

bushing we assume the housing bore is to the nominal size, i. e., 1.937 ~:886. The bushing would be supplied with the 0. D. 1.940 ±.:88?.

The aforegoing information is provided as a basic guide to assist the designer as to the best and most economical practices for Lubrite. Should the design or application require deviation from the above, our complete facilities make it possible to meet the most exacting requirements.

*"Close-in" due to press fit considered.

LUBRITE LUBRICANTS

Lubrite products are unlike many other so-called "oilless", "graphite" or "self-lubricating" items in that Lubrite lubricants are completely self-lubricating and do not require supple mentary lubrication at varying intervals o.f time. Other "similar-appearing" graphite type bushings have not been able to duplicate the low coefficient of friction and performance of Lubrite.

The Lubrite lubricating film does not break down under severe static or slow moving loads as an oil or grease film tends to do.

Lubrite lubricants have been developed to meet nearly all possible conditions of operation.

Specific Lubrite lubricant formulae have been developed to operate best under specific operating conditions.

STANDARD LUBRITE LUBE

This lubricant will meet the great majority of requirements of operation and is supplied on all orders unless the operating conditions warrant our providing a more practicable grade of Lubrite lubricant for the application. Typical uses are as follows:

GENERAL DUTY

UNDER WATER

IN STEAM (not super-heated)

TEMPERATURE RANGES UP TO 250°F

SUB-ZERO TEMPERATURES

EXPOSED TO THE ELEMENTS

If your conditions are other than standard, we should be advised details of your operating conditions to insure our selection of the proper lubricant, i. e., temperature range, and/or, in presence of oil or grease (intermittent oiling or oil bath), and/ or, presence of acids or corrosive gasses, and/or must operate in solvent solution, etc.

Since the proper lubricant for the application is the key to Lubrite success, it is important that you obtain the recommendation of our Engineers for your specific conditions.

FINISHES

It is not necessary to provide a ground or polished surface on the pin or shaft. A plain machined finish, approximately 125 microinch rms is all that is desirable. The Lubrite bushing is also supplied with the same finish. This class of finish has proven most satisfactory in conjunction with Lubrite lubrication.

COEFFICIENT OF FRICTION

Lubrite Bushings will run at a coefficient of friction from 0.035 to 0.07 for medium and heavy loads, and, approximately 0.09 for light loads. The coefficient, being a function of the :speed and the load, varies with the operating conditions.

FOR DESIGR it is suggested that a coefficient of friction of ten (10) percent be used. For high temperature and extremely light load applications, it is suggested that o value of fifteen (15) percent be used.

The following information will prove helpful to us and assure your obtaining the proper Lubrite product for the application involved. We vary the bearing metal and the Lubrite lubricant £ormulae to give best performance for your conditions of operation.

THE CHEVRON TRADE-MARK

GENUINE CHEVRON PACKING is manufactured only by The Garlock Packing Company. It can always be identified by the registered trade mark ~bove which appears on a tag attached to every set of Garlock CHEVRON Packing ..

GARLOCK CHEVRON* PACKING

for rams, plungers and reciprocating rods

1. Assures a low friction, positive seal.

2. Lasts much longer, needs less maintenance than ordinary V-type packing.

3. Works efficiently in a shallow stuffing box.

*CHEVRON is a registered trade-mark of The Garlock Packing Company

Garlock CHEVRON packing is entirely different from ordinary V-type packings. CHEVRON packing has an exclusive hinge-like construction. This permits free oper ation with minimum friction at all pressures.

With increasing pressures CHEVRON packing rings tighten to prevent leakage. As pressures decline, the rings instantly ease off and permit free operation of the rod, ram or piston without leakage.

On a machine with hydraulically operated clutches ¾" cylinder, maximum pressure 500 p.s.i., service inter mittent, maximum travel ¾"-customer used cups, then O-rings, neither of which worked well. Now packedwith Garlock 431 CHEVRON 3/s" x ¾" x 13/32" deep and do:

a smooth, positive sealing job. ~·

IF IT ISN'T GARLOCK IT ISN'T CHEVRON PACKING

The low-friction properties plus the variety of materials in which CHEVRON packing is furnished, assure long life. Also, with proper initial adjustment of the gland, no later adjustments are necessary to compensate for varia- · tions in pressures.

The design of Garlock CHEVRON packing permits the use of a greater number of rings in a shallower stuffing box depth than is the case with ordinary packing. For further information see the depth tables on pages 4, 5 and 7.

On hydraulic press-40" ram, 6000 p.s.i., ram honed and chrome plated, gland machined to give clearance of .006" between gland and ram, Garlock CHEVRON packing size 40" x 41 ½" x only 2" deep gave 14 years service.

FURNISHED IN RINGS

Garlock CHEVRON packing is furnished in ring form only. It is usually supplied in complete sets, consisting of a top and bottom adapter ring conforming, respec tively, to the bevel of the gland and stuffing box, and a sufficient number of CHEVRON rings to make up the required depth.

For depth tables see page 4, 5, and 7.

ADAPTER RINGS

Top and bottom adapter rings are usually made of the same ma terial as the CHEVRON packing rings. However, for pressures above 3000 p.s.i., the use of filler rings and/or rockhard or metal adapter rings (see page 6) is suggested.

The table below is for general guidance. Many satisfactory CHEVRON packing installations can be made with pack ings smaller or larger than the sizes indicated and with a lesser or greater number of rings than shown.
