Base on the combinations of properties & performance capabilities; Eu has greater application range than other self-lubricating bearings. Thin-wall compact, lightweight, Eu bearings are economic & convenient to use.
EU Brief Description
EU tri-layer maintanence-free bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. PTFE mixtures are impregnated into the intersice of this bronze layer after rolling process completed. Eu has good physical & mechanical properties, also has certainly chemical properties. It is suitable for rotary, oscillating movement with performance of self-lub. Anti-wear, lower firction, lower noise.
1. Self-lub. Layer PTFE Mixture 0.01-0.03mm. After rolling process completed, PTFE mixtures are filled in intersice of bronze layer. Under normal operation, Part of PTFE mixture on top layer will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2 .Porous Bronze layer; The layer provides bonded strength of Self-Lub. Layer.
3 .Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer

Base on the combinations of properties & performance capabilities; Eu has greater application range than other self-lubricating bearings. Thin-wall compact, lightweight, Eu bearings are economic & convenient to use. EU’s PTFE-based bushing surface permits smooth, low coefficient of friction, low wear rate operation with no lubricant, no maintenance & dry running. During operation, the transfer film created will protect the mating shaft surface. EU bearings has great capacity of load & wild range of operation temperatures from-190 to 280, can be suitable for rotary, oscillating and axial sliding motion.
The following list covers some of the many types of EU bearing applications.
Typical applicaiton in this area include: accelerator linkages, brake, clutch foot pedal, reflector control, windscreen wipers, windscreen lift system, roof window system, gear level, door hinges, door lock, seat belt system, seating system, shock absorbers, engin absorbers, carburetor, trunk & bonnet hinges, suspension ball joint, throttle valves, steering columns, steering rods, king-pin assemblies etc.
