VIIPLUS bimetal bearings take steel backing as base The
bearings are sintered with CuPb10Sn10, CuPb24Sn4,
CuPb30, CuSn6Zn6Pb3 or AlSn20Cu after press. It can
insure the bearings O.D. Precision against the friction
between O.D. And housing after pressing it into housing
because of mild steel as its base. The chemical changes of
inner alloy layer can make the bearings work well under
various load presses, different working temperatures and
sliding speeds. Different structures of oil grooves and oil
Indentations can satisfy different adding oil ways and
prevent the bearings from gripping shaft.
The structural characteristics
Bimetal composite bearings with high quality low carbon steel as substrate, the surface of the sinter with low friction properties of copper alloy (CuPb10Sn10 CuPb6Sn6Zn3 CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as wear-resisting layer of bearing, can need according to the operating conditions of copper alloy surface processing of various types of oil tank, oil hole, hole, etc., in order to suit to cannot continue to go hard or go occasion.Good joint strength and optimum bearing capacity can be obtained by the secondary sintering and extrusion.
Bimetallic self-lubricating bearing (foreign says deva. Bm) is a high quality low carbon steel, bronze sheet or stainless steel plate as substrate, spherical bronze powder as middle transition layer on the surface, at the same time to sintering rolling with solid lubricant (graphite) copper alloy as friction surface layer of a kind of self-lubricating composite bearing material, the rolling and sliding bearing.The material has the advantages of self-lubrication, high bearing capacity, good anti-friction and wear-resisting performance, applicable temperature, wide range of medium, simple structure, compact size, and can work in the condition of non-oil lubrication for a long time.
Bi-metallic composite bearing material consists of steel backing with lead bronze or lead-free copper alloy
Bronze Gleitlager Viiplus Bearing Bi-metallic composite bearing material consists of steel backing with lead bronze or lead-free copper alloy(CuPb10Sn10,CuPb6Sn6Zn3,CuPb24Sn4,CuPb30,AlSn20Cu)lining, bearing material for oil/grease lubricatedapplications. The copper alloy forms a continuously frame for thermal conductivity. These bearing structures are with highload capacity and good fatigue property. Higher tolerance can be achieved after re-machined from the customers. Lead-freebronze lining bearing material conforms to the European RoHS directive.
Angineering machine: underpan, thrust wheel, Towing wheel, Steering knuckle,tension pulley...Automotive:trunnion shaft, connecting rod, valve rocker, camshaft, gear box, internal-combustion engine,And Plunger pump friction plate, gear pump friction plate...
According to the different working conditions, different alloy material (CuPb10Sn10,CuPb6Sn6Zn3,CuPb24Sn4,CuPb30,AlSn20Cu,CuSn8Ni)can be sintered on steel backing.-

It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, tailgate pivots, mechanical handling and lifting equipment, hydraulic motors, agricultural machinery etc.
· Bimetal bearing with steel backing and bronze overlay
· Particularly suitable for high specific loads with oscillating motion and low frequency
· Applicable in rough operation conditions
· High load capacity, very good resistance to fatigue strength at higher temperatures
1.Sintered bronze lazer: God wear resistance and excellent load carrying capacity.
2.Steel backing:Setting the foundation of the bushings,the steel back provides exceptional stability, load carrying and heat dissipation characteristics.

Bearing forms made to order: cylindrical bushes and thrust washers with non-standard dimensions, sliding plates, customized bearing designs
Construction machinery: chassis travelling mechanism supporting wheel shaft sleeve, towing wheel shaft sleeve, tensioning wheel shaft sleeve;
Automobile industry: balance shaft bushing, steel plate pin bushing, steering knuckle main shaw shaft sleeve, connecting rod shaft sleeve, valve rocker shaft sleeve, camshaft shaft sleeve, differential shaft sleeve, transmission shaft sleeve, internal combustion engine spindle bush, thrust washer;And piston pump side piece, gear pump side piece and so on.
In practical application, different grades of alloy can be sintered on the surface according to different working conditions.
This material is recommended to be used under the medium speed and medium load condition with oil or grease lubricating. It is widely used for motor rod ends, Kingpin bushing, undercarriage rollers, hydraulic cylinder rod eyes of construction machines and spherical joint bearings of agricultural machines. Because this material is with lead, the specific parts are not allowed to be used according to certain laws or regulations.
