WD-LA Series Slew Drives

  • Worm Gear Drive System
  • Painted Cast Iron Housing
  • Designed for Outer Ring Rotation
  • Totally Enclosed Ball Bearing Support
  • Ready for Hydraulic Motor Mounting

Lubricant Requirements

Applying a small amount of an NLGI #2 lithium-based grease with no solid additives such as MoS2 (molybdenum disulfide) is recommended for quiet operation and long life.

These drives perform best when mounted in horizontal plane.

Contact area between worm and ring gear have been optimized for best performance.
