Products
CBL-20 is triple-layer self lubricating material that can filI modified POM plastic as su rface layer; it is benignant boundary Iubrication materiaI, therefore, it is particularly applicable high-load low-speed rotating and wing movement, as well as in the condition that frequent loaded start-stop is the requirement while hydrodynamic lubrication membrane is difficult to form, in the parts such as bearing, thrust washer, sliding block, ball socket and so on. CBL-20 can take full advantage of less grease to work long time without lubrication maintenance under boundary Iubrication condition. But under oil-free condition, CBL-20 the frictional behavior and permissible PV value ls relatively low, so generally storage pit can be formed on the plastic surface, where lithiumbased lubricant grease or silicone grease and so on should be applied when being installed.
Material Structure
Applications
Note: Various materials are suitable for CBL-20 series products according to different working conditions, such as bronze-backing, stainless steel backing and lead-free material. CBL-2Y is an environmental friendly lead-free product and its color is yellow.
Products are widely used in:
Pedal assembly, balance bushings, brake calipers, steering main pin sets and truck tailgate bushings, truck, crane, car cranes, forest machinery, packaging machinery, construction machinery, hydraulic motors, agricultural machinery mining machinery, metallurgical machinery, irrigation machinery, automobiles, and steel rolling industries.
