  • Thin walled bearing  – Nunc lacinia turpis imperdiet ligula malesuada molestie
  • Bimetallic bearings – Mauris sed felis et libero consectetur auctor id in nisi
  • Bimetal Bearings Size – Flanged bushing, cylindrical bushings
  • Steed backed bushings – Steel backed bimetal bearings have high load capacity and very good resistance to fatigue at high temperatures.
  • Bimetal Bearings quality – Quality and environmental respect are essential to our core values.

Bimetal Bearings is a low-maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory.

bimetal bushing lubricating groove type design

Bi-metallic bushing is formed from steel strips with sliding bronze alloy lining material. The alloy lined surface can be machined oil grooves, holes, formed Indentations etc according to different application. It is suitable for high load, lower speed oscillation & rotation movement.

we offers a complete range of different types of high performance bimetal bushing bearings in order to meet operating requirements of numerous applications and in diverse and difficult operating conditions such as high loads, shock loads, low and high operating temperatures, abrasive environments, etc.
bronzelube.com offers high quality bimetal bearing bushings products and solutions for global industry
Design engineers are increasingly replacing roller or needle bearings with bimetal bearing bushings in a wide range of applications. Due to the simplicity of their design and cost effectiveness, bimetal bushings bearings offer a number of distinct advantages.
Bimetal bearing sliding layer CuPb10Sn10、CuPb6Sn6Zn3、CuPb24Sn4、CuPb30、AlSn20Cu、CuSn8Ni.
Bimetal bearing is a wrapped bushing material consisting of a steel backing material and a bronze sliding layer.

Bimetal bearing bushing buckle oil hole design
In the bimetal bearing bushings design, if the following oil hole is used, the bimetal bearing bushings product can be fully lubricated in use. If there is no special requirement, this oil hole design is also applicable.

Oil Hole is necessary to design if bimetal bearings have lubricated sufficiently; the following oil hole design is recommended, which is also suitable for bimetal bearings series without special requirements.
Bushing O.D. (D)Φ14>D ≤ 22Φ22>D ≤ 40Φ40>D ≤ 50Φ50>D ≤ 100Φ100>D ≤ 180
Oil Hole Diameter (mm)34567
Oil hole location should keep away from the split gap & loading area, and in favor of oil-taking.

Bimetal bearing oil holes should be located away from joints and bearing areas and should facilitate oil intake.

bi-metallic bushing
CuPb10Sn10
It has high fatigue strength, high bearing capacity, high impact resistance and wear resistance, suitable for medium to high speed applications such as gear box, rocker sleeve, main pin, transmission device, common sleeve and so on
bi-metallic bushing 
CuPb24Sn4
It has high anti-fatigue strength, bearing capacity and anti-impact force, and good surface sliding performance. It is suitable for medium speed and medium load. When the surface is coated with soft alloy, it can be used for high-speed internal combustion engine spindle sleeve and connecting rod sleeve.
bi-metallic bushing 
CuPb30
Has very good sliding performance, good bite resistance. It is a kind of special material, the surface is not suitable for processing oil groove and oil hole, generally need to be plated with soft alloy.
