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.

Mounting Suggestion



Housing ØH7

Bushing inner-Ø after mountingH9

Shaft tolerance f7

Housing: Mounting bevel min. 1.5 mm x 15-45°

Shaft Material: Steel, hardened or untempered, surface roughness ≤ Rz 4-6

Shaft: Mounting bevel 5 mm x 15°, edges rounded

The application of an adequate force fitting mandrel is advisable. Grease
lubrication of the outer surface may

be necessary when mounting.

Stick-in: Adhesive should not contact the sliding surface
