Product Details

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.

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
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.
