 Professional Manufacture for Bearings

                    SJ/JF DYB300 Series Bushings 


Product Description

Bushing Models: 





JF bimetal bearings are widely used in oil lubricating situations. Normally under low speed and oil lubricating situations assemble with grease and work with adding oil periodically, such as suspension, steeping ball joints, brake pedal joints, redirector, connecting rod, slide part punch, etc.




The bearings surface are sintered with CuPbSn10, CuPb24Sn4, CuPb30, CuSn6Zn6Pb3 or AlSn20Cu. The chemical changes of inner alloy layer can make the bearings work well under various load presses, different working temperatures and sliding speeds.
