STRUCTURE AND COMPOSITION
Steel Backing and Leaded Bronze Overlay
Steel + Sliding layer CuPb10Sn10 with indents
Steel copper-plated or tin-plated
- 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.

Bimetallic Material Characteristics
- Lubrication Design
- Split Gap Design
- Oil Hole Design
- Application
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.
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. | |||||

| Oil Hole Diameter (mm) | 3 | 4 | 5 | 6 | 7 |
| 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.
Bimetal Bearings Application
