Title The performance of prorietary and AAR specification brake cylinder lubricants at 150ºF. and -50ºF. Author New, L.D. Patterson, B.I. Institution National Research Council Canada, Division of Mechanical Engineering, Fuels and Lubricants Laboratory Date 1965-01-31 Abstract The performance of AAR Specification 914 -42 and 914 - 62 and proprietary lubricants , in IQ - in. air brake cylinders, was compared at 150°F . and at - 50°F. A proprietary non- soap thickened polyglycol grease, containing MoS2, was best in endurance tests at 150° F. and in piston release time comparisons at - 50°F . AAR 914 -42 Specification materia1 provided reasonably good lubrication at 1S0°F., but release times were high at - 50° F. Experimenta1 low temperature formulations pre pa red to meet AAR Specification 914 -62 were , in general , less effective at 150°F. The addition of MoS2 in various amounts did not significantly improve the effectiveness of poor performers at 150°F .
