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.

Special materials for bimetal bearings sheet, bimetal bushings manufacture

Bimetal Bearings Dimensions and tolerances follow ISO 3547 and plain bearings bushings specifications

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.
