Bimetal bushings – High Quality Factory Products –‎

Bimetallic self-lubricating bearing used high quality low-carbon steel plate as base, sintered porous bronze as its surface, suitable

for rotatory oscillating, reciprocating movements on the conditions of high load.low speed, low friction, well wear resistance, long

lifetime and better prevent from holding-on.The bronze layer surface can be machined with various of grooves, oil pockets in

terms of different work condition.The product is widely used in mining machinery, automobile, building machinery, agriculture equipment, rolling steel industry etc.

Bimetal Lead-Free Plain Bearings

We can add lubrication slots and holes to the plain bearing bushing.The plain bearing bushing is made to DIN ISO 3547.The length of the standard bushing can be shortened.We also manufacturer the bushing according to the size you define.A half shell is also available.

Bimetal Bushings Feature

Lead bronze bushing material with bronze and bimetal liner suitable for oil lubricated applications. This material has a high load capacity and good fatigue properties. It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bushes, pin bushings, tailgate pins, mechanical transmission and lifting devices, hydraulic motors and pumps, agricultural machines etc.

Bimetallic bearing containing spherical oil holes or grooves

  • Easy to assemble and lubricate, easy to maintain
  • Good fatigue strength, wear resistance and corrosion resistance
  • Oil groove or oil hole can be designed as required
  • Can supply straight sleeve, flanging, gasket and other styles
  • Standard or non-standard bearings can be supplied on request
  • DIN 1494 / ISO3547

According to the technical data of bimetallic bearing materials

The bushing is pressed into the assembly hole and is thus adequately secured.The mandrel must be used as a press-in guide to avoid damage to the bushing and to maintain bearing clearance.

Bimetal Bushing Structure

1.Bi-metal Sintered bronze layer: good wear resistance and excellent bearing capacity.
2. Steel Backing: By laying the foundation of the bushings, the steel support provides exceptional stability, bearing capacity and heat dissipation.

Bimetal Bushing Material

Steel back, Bimetal Bushing,lead-free, RoHS compliant For lubrication applications.

The bimetallic bearing is made of high quality low carbon steel with the surface sintered with lead-tin bronze alloy CuSn10Pb10.Rolled spherical oil holes on the surface of the alloy facilitate oil storage and effectively reduce wear.The steel back can be plated with anticorrosive coating as required.Suitable for medium load, medium to high speed, and bearing with large impact load, used for rolling bearing, thrust gasket, internal combustion engine piston pin bush.

Special Manufacturer
