Product Features

  • Space-Saving

    The motor can be mounted in a 90° bend, saving installation space.

  • High Rigidity and High Torque

    The use of integral needle roller bearings significantly improves rigidity and torque.

  • Easy Installation

    Can be installed on any brand of motor.

  • No Grease Leakage

    Uses high-viscosity, non-separating grease, effectively preventing grease leakage.

  • Easy Maintenance

    No grease changes are required during the product lifecycle, making installation even easier.
