Even though ESG Bearing has successfully made our rolling mill roller bearings with steel cage, brass cage is still popular among some clients. In order to make their preference and our persistence for a better performance meet, ESG Bearing has been searching and testing better brass material for our cage. And now we are proud that MISSION COMPLETE.
ESG Bearing is now able to offer our clients with a better performing brass cage, with higher antifriction and impact resistance.
