HKB650GT Steel shell cast bronze with graphite plug

Casting high-strength copper alloy on the surface of high-quality carbon steel as the base material for bearings, this manufacturing process achieves complete metallurgical bonding between copper and steel, reducing material costs while also improving its load-bearing capacity; And according to the operating conditions, embedding solid lubricants on its working surface greatly reduces the friction coefficient of the bearing and achieves the purpose of self lubrication.
