When assembling. smear lubricant grease on inner hole

Application Characteristic

1. Function is outstripping other known boundary lubricating material under the less oil working situation.
2. Friction surface is thick and solid and has good wear resistance.
3. High mechanical strength, it can stand heavy dynamic and static load. It is used in high load capacities and low speed with rotational, oscillating or frequent stop-start motion.
4. It can work long time without oil in the condition of boundary lubrcation,under oil or grease lubrication interval, the work is longer

5. Surface plastic layer can remain margin when it is machine shaping. It can be equipped with pushing into the hole by itself to get a better mounting dimensions.
6.The produce can be applied in auto chassis, forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.
Provide standardized products:Cylindrical bushes P4, flanged bushes P6, thrust washers P7, plank stuff P11.
Provide standardized products:Cylindrical bushes, flanged bushes, thrust washers, plank stuff, gap block, return board, steel bushing subassembly.

* 장점

 베어링면에 산재한 윤활 포켓에 의하여 급유 횟수를 최소화 할 수 있습니다

 두께가 얇으면서도 고하중에 사용할 수 있어 소형 경량화 설계에 이상적입니다.

 내마모성이 우수하고 작동 상태가 정숙합니다.

 편심에 강하고 내면 적살이 가능(아세탈수지)하여 치수 정도를 조정할 수 있습니다.

 표준화 생산되어 납기가 빠릅니다.

 그리이스(Greasa)윤활시 마찰계수(μ=0.01~0.15)
