PROPERTIES
For high load capacity and oscillating movement, as well as for rough operation and temperature load. Long-run lubrication because of lubricant storage.
RANGE OF APPLICATION
Track rollers, construction machines, crane construction, agricultural machines (impact loading)
MAINTENANCE
It is a low-maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory.
MOUNTING ADVISE
HousingMounting bevel min. 1.5 mm x 15-45°
ShaftMounting bevel 5 mm x 15°, edges rounded
The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
GluingAdhesive should not contact the sliding surface!

What is the best material for bushings?

* Our enterprise, is one of the undisputed supplier of the highly competitive bimetal bearings & bushings industry in china.

bimetal bearings sleeve bushings

Bimetal Bushing in metric size or non-standard bearings,Steel Backed Bronze Bushing.Our Bi-metal Bushings include track roller bushing, carrier wheel bushings, guiding wheel Flange bushing etc.

Bi-metal bearing is steel backed with low friction and excellent wear resistance bronze powder as bearing layer. Different kinds of oil groove and oil hole are designed as per lubrication conditions and operating condition and Bi-metal engine bearing with bearing layer in CuPb10Sn10 is widely used.

Made of a high quality low carbon steel backing carry a tin-lead-bronze alloy (CuSn10Pb10) as a sliding layer. In order to improve tribological behavior the sliding layer can be machined with ball shaped indents to store oil or grease. In case of corrosive environment the backing can be copper plated. Products of bi-metal bearings series are applied in operating conditions under medium loads, medium or high running speeds and high impact loads. Bi-metal Bushing is used for wrapped bushes, thrust washers and bushes in connecting rods of gas engines, etc.

Characteristics

Suitable for oscillating motion under high-load and low-speed condition.

Applicable in extremely tough working condition.

Excellent fatigue strength under high temperature.

BIMETAL BEARING MANUFACTURING

Bi-metallic composite bearing material consists of steel backing bushings with lead bronze or lead-free copper alloy (CuPb10Sn10、CuPb6Sn6Zn3、CuPb24Sn4、CuPb30、AlSn20Cu)alloy lining, bearing material for self-lubricated applications. The copper alloy forms a continuously frame for thermal conductivity. These thin walled bearings structures are with high load capacity and good fatigue property. Higher tolerance can be achieved after re-machined from the customers. Lead-free bronze lining bearing material conforms to the European RoHS directive.
