Application Feature

Good load capacity and anti-wear.

It is used in high load capacities and low speed with rotational,oscillating or frequent stop-start motion.

It can work for a long time without oil in the condition of boundary lubrication,under oil or grease lubrication interval,the working-life will be longer.

It is machinable for the thicker of POW.

The bushes can be applied in auto chassis,forging machine,metallurgical,civil engineering,power station,strip rolling industries etc.

It is widely used in the machine where Lead is unacceptable.

• material handling equipment

• home appliances and consumer goods

 
Lubrication
POM composite plain bearings are designed to operate under marginal lubrication conditions. The sliding surface of these plain bearings contains grease reservoirs which should be filled prior to installation. It is not necessary to relubricate these plain bearings, but the presence of a lubricant can extend the plain bearing service life considerably. To protect the mating surface against corrosion, grease can be applied periodically.
