NRB Taiwan Wears Down the Competition with VICOTE® Coatings In Its Needle Roller Bearings
Victrex plc, a leading manufacturer of high performance materials, including VICTREX ® PEEK™ polymer, VICOTE® Coatings and APTIV™ Film, today announced that its VICOTE Coating has been selected by Needle Roller Bearings Co. Ltd (Taiwan), the leading manufacturer of needle roller bearings, targeted for use in motorcycle engines, outboard motors and other high rotational speed engines. VICOTE 804 Blk was chosen to replace the current coating made of copper and silver plating for its excellent wear and abrasion resistance. VICOTE Coating is believed to reduce the wear on the outer surface of the roller bearing, and thus can enable longer life of the actual cage.
Needle roller bearings are manufactured predominantly for commercial markets including automotive and industrial, but are used in virtually every sector where high speed rotational equipment is utilized. Traditionally, the outer surfaces of the bearing cage are plated with expensive copper and silver layers to reduce wear, following tests under which the bearing was subjected to rotational speeds of 9000 rpm for over 100 hours, the current copper and silver layers wore off, causing damage to the cage and possible premature failure of the bearing; however, the same test was conducted on a bearing coated with VICOTE 804 Blk and the bearing cage showed no signs of wear at the end of the test.
