Oiles 500SP4 High-strength brass bearings with embedded solid lubricant Feature 500SP4 is a self-lubricating bearing with embedded solid lubricant and metal base that conforms to the universally-acknowledged ASTM Standards (C86300). Serviceable without the need for lubrication. Demonstrates high performance under high-load and low-speed operations. Demonstrates superior wear resistance in applications where oil film is seldom produced such as reciprocating motions, oscillation, frequent starts and stops, etc. Superior chemical resistance and corrosion resistance.
