A gear reducer lowers a motor's output speed while multiplying torque, and 3BG Supply stocks worm, helical, cycloidal, and planetary designs to match nearly any drive requirement. Whether you need an inline, right angle, or 90-degree configuration, our gear reducers are built to pair with the electric motors and gear boxes we already carry. Talk to our team if you need help matching a reduction ratio to your application.
Find the right Gear Reducer for your needs.
FAQs
What is a gear reducer?
A gear reducer is a gear box designed specifically to reduce the input speed from a motor while proportionally increasing output torque, expressed as a reduction ratio (for example, 20:1). It is used any time a driven load needs more torque and less speed than a standard motor delivers on its own.
What's the difference between a worm gear reducer and a planetary gear reducer?
A worm gear reducer uses a worm screw meshing with a worm wheel to achieve high reduction ratios in a compact, right angle package, but it runs less efficiently than other designs. A planetary gear reducer uses concentric gears arranged around a central sun gear for higher efficiency and torque density in an inline footprint.
What is a right angle gear reducer used for?
A right angle gear reducer changes the direction of power transmission by 90 degrees while also reducing speed, which is useful when the motor cannot be mounted inline with the driven shaft. Worm and helical-bevel designs are both commonly configured as right angle reducers.
What is a cycloidal gear reducer?
A cycloidal gear reducer uses an eccentric cam and cycloidal disc rather than traditional gear teeth to achieve very high reduction ratios with low backlash in a compact housing. It is often chosen for applications that need precise, shock-resistant motion control.
Does 3BG Supply carry parts from major gear reducer manufacturers?
Yes, 3BG Supply sources gear reducers and replacement parts from leading manufacturers to support both new installations and existing equipment. Contact our team with your current unit's nameplate details for a like-for-like match.
How do I pair a gear reducer with an electric motor?
Match the reducer's input shaft size and mounting configuration (C-face, foot-mount, or shaft-mount) to your motor's frame size and shaft diameter, then confirm the reduction ratio delivers the output speed and torque your load requires. Our electric motors team can help confirm fit before you order.
