Amsted Rail - ASF-Keystone Inc.


The GRC conversion unit is AAR tested and approved under M921B (100k preload) or M-921D (50k preload). The ASF-Keystone GRC line of cushion units are based on conversion of existing M, HD, E, F and ART series cushion devices. The conversion process includes: installing a new larger diameter chrome plated piston rod, round body reservoir for superior weld and low stresses, latest technology seals, preload valves, bearings, piston rings and high-pressure nitrogen gas (eliminating the mechanical spring), the company says. ASF-Keystone also can upgrade existing nonpreload gas return units to the latest AAR specifications. ASF-Keystone is an AAR M1003 quality supplier.
