COB-SRIM 020 Application£º
1.Good load capacity and anti-wear.
2.It is used in high load capacities and low speed with rotational,oscillating or frequent stop-start motion.
3.It can work long time without oil in the condition of boundary lubrication,under oil or grease lubrication interval, the work is longer.
4.It is machinable for the thicker of POM.
5.The bushes can be applied in auto chassis,forging machine,metallurgical,civil engineering power station, strip rolling industries etc.
