Composite Polymer Plain Bearings is used steel-backing as its structure, sintered porous bronze as its interlayer, surface inlaid the modified POM. Suitable for marginally lubricated and dry operation on the conditions of lubrication indents grease. It has been widely applied to metallurgical machinery, Mine machinery, water conservancy machinery, vapor locomotive, building machinery, agriculture machinery, steel rolling industry etc.

Material organization
Advantages
POM composite bushings are referred to as prelubricated because their material is designed to operate with marginal lubrication. These bushing type effectively fills the gap between fully lubricated and dry sliding bushings. viiplus offers a wide range of straight POM composite bushings. Advantages of these bushings include:
maintenance-free operation
very good frictional properties
high load carrying capacity
high sliding velocity
small operating clearance
POM composite bushings are suitable for applications where a sliding material with self lubricating properties is a prerequisite. Application area examples for these bushings are:
- agricultural equipment
- construction machinery
- 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.
