7 Ways the Morse Raider Gearbox Creates Stress-Free Maintenance

  1. Motor Push Off Holes

    Reduce headaches and save time when removing the motor using the push off holes. This feature greatly helps when fretting corrosion is present in the quill input style as fretting hinders motor removal.

  2. Seal Guard

    Less risk of input seal damage during transit, installation or storage. It saves you time as replacing a seal can take one hour or more.

  3. O-Ring Housing Seals

    Improved leak prevention for less mess and longer life as gearbox will better retain lubricant and an o-ring is more reliable than a gasket.

  4. Worm Thread Rolled, Nitrided And Ground

    Other gearbox designs just roll the worm thread, the Raider worm gear box is also ground, which creates a smoother, quieter operation and overall better performance and longer life.

  5. Single Output Cover

    The Raider gearbox has a cast closed housing on one side which is one less place it can leak.

  6. Viton®* Double-Lip Seals

    Improved seal life. Viton seals have higher upper and lower temp limits, which enables longer life in a standard plant environment.

  7. Availability

    Make an easy transition to the Morse Raider gearbox with a Gap Walk® consultation for reliable design and availability.

* Viton is believed to be the trademark and/or trade name of The Chemours Company FC, LLC, and is not owned or controlled by Regal Beloit Corporation.
