Broadly used for heavy load,low velocity application
#500SP1 is based on high strength brass alloy which is processed through unique high-tech cast technique. The anti-abrasion surfaces of the bearing are drilled proportionally and embedded with solid lubricants. Due to its high mechanical strength and hardness, it’s broadly used for heavy load, low velocity application. There are two kinds of solid lubricants available for different application, such as, SL-1 for general-purpose use, SL-4 f
