Delroyd Worm Gear's exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and long service life. The hardened, ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze gear.

  • Delayed engagement produces a "no load start"
  • No slippage at full running speed
  • Controlled soft-start acceleration
