OILES 500SP4 ASTM-standard-based alloy / Plugged solid lubricants bearing

STANDARD PRODUCT CUSTOMIZED PRODUCT

Bearing made of ASTM-standard-based alloy
OILES 500 SP4 is the ASTM version of #500 SP 1 for heavy load applications.This bearing consists of a high strength brass alloy base. Fabricated with an advanced casting technique it contains a proprietary solid lubricant, which is embedded to eliminate the need for external lubrication. Features Exhibits incomparable performance under a high load, low speed operation. Usable without lubrication Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations Remarkable resistance to corrosion and resistance to chemical attack Available in various dimensions standard products
