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.

Advantages

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.
