Product Description

High quality customized Graphite bronze JDB BUSHING

Solid bronze bush is a kind of machined cast bronze bearing which takes oil in inner grooves to work. It can be used in low speed because of larger load, longer life and higher HB than Al-Cu bearing.
Machined Cast bronze bearings offer technically and economically favourable bearings solutions.
