Key Features

  • Available in single, double and multi-row configurations, as well as proprietary sizes
  • Designed in collaboration with OE engineers to design, engineer and test bearings for premium performance in many applications
  • Power dense designs allow for heavier loads and can help extend bearing life
  • Optimized internal geometry lowers torque and operating temperatures to extend lubrication system life
  • Can be designed to withstand high-corrosive, high-temperature and vacuum or low-lubrication environments with proprietary enhancements
