About this file
This document is a Minimum Specifications sheet for a federal procurement outlining Navy requirements for precision measurement equipment.
The Navy requires purchase of a Labmaster Universal Model 175, a calibrated two-point contact instrument capable of dimensional and radial clearance measurements for precision ball bearings. The instrument must achieve resolution to 0.000001 inches (one millionth of an inch) for both dimensional and radial clearance measurements, with NIST traceability and ISO 17025/A2LA accreditation. The contractor must provide 23 specific components including the base instrument with GageCal software, various probe kits (ruby tipped, flat, and internal dual probes in three size ranges), measurement accessories, calibration reference materials, a 30x60-inch table with three drawers, radial and axial internal clearance kits, and a Tsunami Filter. All components are identified by specific part numbers. In addition to procurement, the contractor shall ship all components to Naval Surface Warfare Center, Carderock Division in West Bethesda, Maryland, establish onsite hardware and software setup, and provide onsite training for three personnel on equipment usage and purchased kits. Delivery is required no later than September 30, 2026, on an FOB Destination basis. The applicable reference document is Military Specification MIL-DTL-17931F for Bearings, Ball, Annular, for Quiet Operation, dated February 7, 2025.

MINIMUM SPECIFICATIONS
Title: Labmaster Universal 175
1.0 SCOPE: Navy requires purchase of new calibrated two-point contact instrument with radial clearance measurement capability. The instrument will come calibrated with traceability to a national standard, in turn having traceability to ISO, giving technical credibility to dimensional measurements taken.
2.0 TASK: The Labmaster Universal 175 accomplishes both dimensional measurements to a resolution of millionths of an inch (0.000001 inches) and radial clearance to a resolution of millionths of an inch (0.000001 inches). MIL-DTL-17931F lists tolerances at +/- 0.0001 inches for dimensions and approximately +/- 0.0003 inches for radial play. These tolerances dictate a minimum level of resolution of 0.00001 inches (10 millionths of an inch), or better if a machine is able to go out more decimal places.
3.0 MINIMUM SPECIFICATIONS: Contractor shall provide all hardware and software required to conduct dimensional and radial clearance measurements of precision ball bearings. Final output of hardware should result in NIST traceable dimensional and radial clearance measurements to resolution as specified in 2.0.
3.1 The contractor shall provide
3.1.1 Labmaster Universal Model 175 (including GageCal software) calibrated by an accredited ISO 17025/A2LA laboratory.
