| 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! | ||
it is widely used in throttle valve ,shaft,throttle lever , hydraulic motors, agricultural machinery etc.
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.
