Open nylon cage bearing is one type of deep groove ball bearing without dust seals. It is often used in the mine. has better anti-stuck performance and wider range of temperature than iron cage. In the underground its anti-static performance is also better. It is best cost-effective bearing for idler roller. International market generally use TN nylon retainer and TN(TNGH) nylon retainer with glass fiber, liable to break. The selection of open nylon cage is crucial to KA bearing, while the material of nylon cage must be pure and has enough toughness and strength, because the cage will get very soft if it is made of bad material or mixed material, thus to make no anti-stuck performance within the bearing. To get safety certificate for coal mining products must use open nylon cage bearing.
