UF850 is backing on 20# steel, sintered with CuSn6Zn6Pb3 bronze powder. It has the same performance with bronze casting bushing, but with lower cost. Comparing with the bronze casting bushing, UF850 has more stable chemical composition and better performance on shaft seizing resistance. It can be used in hydraulic cylinder as guide bush, and the sliding area in construction machine. And fit for other application with high precision and low speed.

Liner material: CuSn6Zn6Pb3

Load capacity: 65N/mm2

Temperature Max: 260℃

Liner hardness: HB70~100

TECHNICS DESIGN

UF850 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.

APPLICATION FEATURES

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.

Maintenance-free Bearing & Bushings

Bearings are self-lubricated, suitable for improper or non-lubricated extreme conditions of operation, not continuous maintenance and need a longer service life of the application.With high load capacity, excellent anti-corrosion performance, shockproof performance, high efficiency bearings are perfectly applied in a wide range of applications, including:

Charging trolley
Drive roller,
Ladle cover manipulator
Lifting/regulating equipment
Casting cylinder with locking device
Pinch roller polishing machine
Milling cutter screw - nut
Quenching machine slide plate
Industry Self-lubricating Bearing & Bushings advantage

Highly efficient self-lubricating bearings provide customers with significant advantages in many applications in major metal industries, such as long service life, high wear resistance and low friction under various load, speed and temperature conditions:
· low friction and high wear resistance
· improve performance and extend service life
· raise the operating temperature
· reduce system costs
