Flexible-Mount Right-Angle Speed Reducers for Face-Mount AC Motors

With output shaft openings on both sides, these speed reducers adapt to fit multiple configurations. Use them to transmit motion at a 90° angle while reducing speed and increasing torque. All are permanently lubricated to save maintenance time and effort.

Plug-in shafts (sold separately) convert output drives from female to male. Shafts for two outputs are long enough to extend from both sides of the speed reducer.

Radial Load Capacity—Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.

Right-Angle Speed Reducers

Reduce shaft speed and increase torque while transmitting motion at a 90° angle. Speed reducers require lubrication (not included). Connect to a motor using a shaft coupling (not included).

Radial Load Capacity—Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.

Mounts—Gear Box Mounts (sold separately) allow you to mount speed reducers to machinery or other surfaces where fastening into the bottom of the speed reducer is not possible.

Low-Profile Right-Angle Speed Reducers

The input and output shafts are positioned at the same height, so these speed reducers take up less than half the vertical space as our standard right-angle speed reducers. Use them to transmit motion at a 90° angle while cutting shaft speed in half and doubling torque. All are permanently lubricated to save maintenance time and effort. Connect to a motor using a shaft coupling (not included).

Sanitary Right-Angle Speed Reducers

Cut shaft speed and increase torque while transmitting motion at a 90° angle in food, pharmaceutical, and other sanitary environments. Made of stainless steel, these reducers won’t corrode from frequent washdowns with harsh cleaners and sanitizers. All have a rounded design and polished surfaces, so there are no crevices where bacteria can grow, reducing the chance of a foodborne illness. Double input and output seals block out contaminants and prevent lubricant leaks.

These speed reducers have multiple gear teeth that are engaged at the same time to create more torque than other same-size reducers. They’re also more durable for a long service life. All are permanently lubricated to save maintenance time and effort. Connect them to a motor using a shaft coupling (not included).

IP69K Enclosure Rating— Rated IP69K, they’re dust- and water-tight against high-pressure and high-temperature washdowns.

Radial Load Capacity—Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.

Sanitary Right-Angle Speed Reducers for Face-Mount AC Motors

With a sanitary design for food-processing environments, these speed reducers mount to the face of your motor—no coupler required—to slow shafts and increase torque while transmitting motion at a 90° angle. The 316 stainless steel housing resists corrosion from frequent washdowns with harsh cleaners. Rounded edges and a polished surface make the housing easy to clean and leave no crevices for bacteria to grow in. To protect against leaks and contamination, they have double input and output seals.

Since multiple teeth come in contact at once, these speed reducers are more durable and create more torque than other speed reducers of the same size. They’re often used to generate large amounts of torque in tight spaces. To save maintenance time, they’re permanently lubricated.
