Suitable for any direction of motion with excellent wear performance.
DNB#200S is bimetallic bearing material, based on steel backing, and a layer of copper sinter, which is composed of special copper powder with solid lubricants (major ingredient is graphite) dispersed, acts as wear resistant surface and processed through oil-impregnating treatment.
lSelf-lubricated and maintenance-free.
lAny direction of motion is acceptable due to solid lubricants dispersed evenly in the mating surface.
lHigh load carrying capacity , excellent wear resistance, good velocity performance.
lFurther machining allowance is available
