Bimetal Bushing 800 Throttle Lever & Valve Bimetal Bearing Bushes Tin Bronze Lead Alloy With Antifrication Overlay
Throttle Lever & Valve Bimetal Bearing Bushes Tin Bronze Lead Alloy With Antifrication Overlay
Bimetallic sliding bearings are designed and made in China and can be customized to meet specific indentation and shape requirements.Steel Backed Bimetal or Trimetal Composition Throttle Lever & Valve Shaft Bimetal Bushings Tin Bronze Lead Alloy With Antifrication Overlay
Throttle valve is a valve that controls fluid flow by changing the throttle section or length.The throttle valve and one-way valve parallel can be combined into a one-way throttle valve.
bimetal bushing is backed with high quality low carbon steel with tin-lead-bronze alloy(CuSn10Pb10)sintered on its surface . It has high fatigue strength, load capacity and impact strength. The bimetal bushing, and save lot of material, which make the product cost performace higher.

| 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 | |||
| Housing | Mounting bevel min. 1.5 mm x 15-45° | ||
| Shaft | Mounting 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. | |||
| Gluing | Adhesive should not contact the sliding surface! | ||
Application
it is widely used in throttle valve ,shaft,throttle lever , hydraulic motors, agricultural machinery etc.
Structure
1.Sintered bronze CuSn10Pb10: God wear resistance and excellent load carrying capacity.
2.Steel backing:Setting the foundation of the bushings,the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
