This is a Vendor Item Control Drawing for a bearing material component, prepared by the U.S. Army Combat Capabilities Development Command's Chemical Biological Center at Rock Island Arsenal. The drawing documents the technical specifications and sourcing requirements for a self-lubricating bearing material manufactured by The Timken Company.

The bearing material is specified with the following key technical characteristics: 0.5857"/0.685" thickness with a minimum usable width of 5.00", steel backing, porous copper-tin bronze inner structure, PTFE/Pb bearing surface, and no lubrication required. The component must withstand compressive strength of 44,000 PSI, static load capacity of 36,000 PSI, and dynamic load capacity of 20,000 PSI. Operating speed ranges from 1,000 RPM dry to 2,000 RPM lubricated, with a PV limit of 50,000 PSI-FPM continuous or 100,000 PSI-FPM intermittent. The temperature range is -328°F to 536°F, with static and dynamic coefficients of friction both specified at 0.02 to 0.02. The suggested source of supply is The Timken Company located in North Canton, Ohio (CAGE Code 0ZM09, Vendor Part Number S0594DU0500-S1). The drawing was initially released on June 4, 2024, and is approved for unlimited public release and distribution.
