Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 

Steel & Stainless Steel Worm Wheel Gearboxes


 

Steel and stainless steel manufactured worm wheel gearboxes are referred to by several names, including 90-degree gearboxes, right angle gearboxes, speed reducers, flow control worm gear reducers and worm drive gearboxes. These gears are typically made from bronze, and the worms are steel or stainless steel.

Ondrive’s worm wheel gearbox reducers are sturdy, reliable, and application tested. Our worm gearboxes are extremely quiet, delivering low noise output and angular design options encased within a solid steel or stainless steel housing.

Steel & Stainless Steel Worm Gearbox Reducer Benefits

While worm gears are similar to a spur gear, the worm wheel gearbox reducers are significantly smaller than other reduction gearboxes. A primary benefit of steel and stainless steel worm gear reducers is that they produce an output of 90° from the input and can be used to transmit higher torque or reduce rotational speed. A worm gearbox often has right hand threads; if a change in the direction of the output is needed, a left-hand thread worm gearbox is required. View our catalogs and brochures. Additional benefits of worm drive gearboxes include:
  • High reduction ratios
  • High torque multiplication
  • Quiet operation
  • Absorbs shock loads
