  • Cartridge bearing including a stub shaft and an electrically conductive axle and method of using cartridge bearing
    Patent number: 6554117
    Abstract: The invention is particularly useful for coacting with roller tubes of conveyor apparatus. A cartridge bearing including a stub axle with a tip of greater hardness than the surface circumscribing the aperture receiving the stub axle is inserted into an end of a conveyor roller tube. Along with being electrically conductive, the stub axle can be provided with a damper for reducing vibration. The stub axle engages an electrically conductive stub shaft and moves axially with respect to the stub shaft to operatively interlock with the aperture of the fixed structure. Use of the cartridge bearing provides for the grounding of static charge that can accumulate during operation of conveyor roller tubes.
