Ordering Specifications Summary

This document provides standard ordering specifications for 140-360 series cylinders used in suspension systems. The specifications define the technical parameters that contractors must meet when supplying these hydraulic cylinders for federal orders.

The 140-360 series cylinders are specified with a bore diameter of 140 mm (cylinder tube inner diameter) and a stroke length of 360 mm. The cylinders must feature double-acting action type, which is standard for modern suspension systems to control both compression and rebound. Additional requirements include a single rod configuration and mounting styles utilizing heavy-duty spherical bearings or clevis mounts at both ends to accommodate axle oscillation. These specifications establish the mandatory technical requirements for any vendor supplying cylinders under this ordering specification series.
