Inner wall material performance:

CuPb24Sn4: has high fatigue strength and bearing capacity, impact resistance, but because of the high lead content in the alloy and high density are prone to lead segregation, and reduces the abrasion resistance of the bushing at the same time also makes the combination of alloy layer and steel back strength is reduced, the high cost of the copper layer used in high speed, swing and rotating wages under the condition of bearing.

CuPb10Sn10: have high fatigue strength and bearing capacity good lubrication performance, wear resistance and corrosion resistant performance is good, suitable Yu Zhongzai, medium to high speed and has a larger impact load bearing, mechanical equipment on the use of rolling bearing, the gasket surface pressure is high, and there is the lateral pressure of the sliding bearing, such as rolling rolling, vehicle use bearing, bimetallic bearing shell, and the piston pin set, lining, etc.

CuSn6Zn6Pb3: Good wear resistance and corrosion resistance, easy to process, good casting performance and air tightness, working under general load, medium sliding speed, such as turbine, motor, compressor, piston clutch, connecting rod bushing, rocker arm bushing, etc., the current consumption is relatively large.

Cusn6.5-0.1: Lead-free bimetallic bearing is widely used in the balance axle bushing, gasket, internal combustion engine spindle bushing, connecting rod bushing, rocker arm bushing, oil pump side friction plate, internal combustion engine bushing of medium and small power, train engine bushing, air press bushing, refrigerator, etc.

ALSn20Cu: With moderate fatigue strength and bearing capacity, good corrosion resistance and sliding performance.It can be used with soft shaft, and is often used for small and medium power internal combustion engine bearing bush, train engine bearing bush, air compressor bearing sleeve, etc. It is the best product to replace Babbitt alloy.


Bimetallic bearing steel material

Due to the stability of the matrix is low carbon steel material, the machining accuracy of the outer diameter of the shaft sleeve is guaranteed, and there is no need for screw fixation after the product is loaded into the seat hole, so the interference fit can prevent the phenomenon of going round outside.The change of chemical composition of inner surface alloy layer can meet the requirements of different bearing pressure, different service temperature and different sliding speed. Oil groove and oil hole with different structure can meet the requirements of different refueling methods and prevent the phenomenon of biting shaft.

The product has the advantages of good wear resistance, etc.It is especially suitable for medium and high speed loading and low speed loading.Various oil slots, oil holes and oil holes can be machined on the friction surface by special technological means, so as to adapt to the use under different lubrication conditions.The products have been widely used in automobile engine, chassis, motorcycle clutch, gear pump wipe plate and lifting equipment and other fields.

Bimetallic bearings for lubricated applications!

Bimetal Bearings:

VIIPLUS is specialized in thin antifriction bearings and notably connecting rod bushings and engine bearings with or without flanges.

VIIPLUS bimetal bearings are manufactured through two distinct types of production: either from a steel backing with a sintered bronze layer or from a steel backing with a white metal layer. Additional layers made of lead or nickel may complete the characteristics of the product.

Bimetallic bearing is made of high-quality low carbon steel back as the surface sintered lead-tin bronze alloy material, through several high-temperature sintering and dense rolling into copper and steel bimetallic strip rolling. The bimetal bushings are one of the strongest in copper and lead alloys, and are widely used in various applications, such as bushing, thrust washer, and so on.

Overview of bimetallic bearings 

Because the matrix is stable as low carbon steel material, the machining accuracy of the outer diameter of the shaft sleeve is guaranteed. Moreover, after the product is loaded into the seat hole, there is no need for screw fixation. The change of chemical composition of the alloy layer on the inner surface can meet the requirements of different bearing pressure, different operating temperatures, and different sliding speeds. Oil grooves and holes with different structures designed on the friction surface in the production can meet the requirements of different refueling methods, prevent the phenomenon of biting the shaft and adapt to different lubrication conditions.
Widely used in automobile engines, motorcycle clutch, light industrial machinery, engineering machinery.


  • High load capacity
  • Works well even in difficult conditions
  • Good lubrication properties because of lubrication indents
  • Wide range of temperature
  • Capable of supporting high specific loads
  • Excellent fatigue strength under dynamic and shock load conditions
  • Suitable for oil and grease lubrication
  • Superior performance under oscillating movement
  • The steel backing provides strength and rigidity
  • Thin wall construction permits compact bearing assembly
  • Indents in the bearing surface provide a reservoir for grease and thus allow extended re-greasing intervals
  • Tolerant of the relatively poor mating surface finish
  • Bush bore may bored, reamed, broached or ball burnished in situ to control the assembled bearing clearance
  • Suitable for oil or grease lubrication
  • the steel backing provides strength and rigidity
  • Hardened shafts are not required
  • Thin wall construction permits compact bearing assembly

Bimetal Bearings Application Field

Oil pump bearings, gearbox bushes, steering gear, power steering, pedal bushes, kingpin bushes, tailgate pivots, brake caliper bushes, machine slides, hydraulic cylinders, hydraulic motors, pneumatic equipment, medical equipment, textile machinery, etc.

Bimetal Bushing is widely used in various past automobile industries such as Truck, engine, transmission cases, Textile machines, vehicle chassis, steering knuckle, trunnion shaft, leaf spring, motorcycle clutches, wear plating of gear pumps, as well as hoisting machine, etc.
