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.
Material Structure
Material: CuSn8P0.3 (DIN ISO 4382-2:1991)
ype | Cu% | Sn% | P% |
ZR-090 Bronze Bushing | 91.3 | 8.5 | 0.2 |
Materail chemical composition refer to the standard of DIN17662 ISO 4382-2: 1991; CW453K
The actual composition proportion is allowed to up or down in certain range based on standard
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.
