Product Description
FB090 CuSn8P0.3 Rolled Bronze Sleeve Bearing WB800 BK090 Bronze Bushing With Lubrication
Indents
ZR-090 bronze bushing is made from high grade alloyed, hot
rolled, phosphorous tin bronze. The slide bronze bearings are especially designed to withstand heavy loads and to be shock-resistant. The
entire bearing sliding surface consists of lubrication pockets that build up a lubricating film that reduces friction, both at startup and during operation. ZR-090 is intended for
radial, oscillating and axial movements and are especially suited for medium to high loads.This type of bronze bearing also called FB090 bronze sliding bearing, WB800 bronze
bearing,PRM bronze wrapped plain bearings,MBZ-B09 Plain bronze bearing,BMZ Bronze self lubricating bearing, BRM-10 bronze sliding bearings and
etc.

ZR-090 Bronze wrapped bushing use high density bronze strips to roll the spherical oil pockets as material structure.We can make rolled bronze bearing with
dimond oil pockets, round oil pockets and smooth suface based on customers requirements.
