ZTOM92 wrapped bronze bearing
Product Name: wrapped bronze bearing
Introduction
Thin wall thickness is the most important peculiarity of the ZTOM90 bearing series.They are light and compact, the inner-layer of the bearing being a kind of high density copper alloy of specoal compositions, there os no hole and pit and provides higher load capacity and faigue strength in compare with readitional casting bronze bearing.It is manufactureed by advanced technology and machines,various kinds of lubricating indentations or grooves maybe readily provided on the sliding surface,and so the re-oiling period id remarkably prolonged and the service life os accordingly prolonged. It's used in agricultural machinery,construction machinery as well as engineering machinery etc.
Advantages
1. Saving copper material, saving labour hours of turning
2.Low weightand low cost
3.Re-oiling period is prolonged usually to five times
4.Gigh loas capacity,particularly fitted for relatively rough wear,mating surface
5.Ready for change,available from stock
Structure of the material
Using high density bronze material rolled diamong shape or spheiacal oil pockets on the surface with a special compostion as its backing has a good performance of anti-fatigue ad anti-abrasion as well as anti-corrosion
