    Speed Reducers for Position- and Speed-Control Motors

    Pair these speed reducers with stepper and servo motors in position- and speed-control applications. Helical gears provide exact positioning and smoother travel than our other speed reducers. Attach to a motor to transmit motion parallel to the motor shaft while reducing speed and increasing torque.

    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.

    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).
