Product DescriptionFB090 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) ypeCu%Sn%P%ZR-090 Bronze Bushing91.38.50.2 Materail chemical composition refer to the standard of DIN17662 ISO 4382-2: 1991; CW453KThe 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. Special DesignsRounded lubrication indentsInternal and external lubricating groovesWithout lubrication indents,smooth surfaceSpherical and plain washers Characteristics Surface can be incorporated with spherical of diamond shaped indentations or oil grooves linear. Particularly suitable for oscillating bearing.High load capacity and long life.Wide temperature rangeEasy to assembleWorks well in dirty environmentsCheap than traditional bronze bush, cost saving.
