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




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. With an IP69K rating, they’ll also withstand dust and high-pressure, high-temperature washdowns. 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).
Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to the shaft, such as pulleys and sprockets.

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. They meet IP65 for protection from washdowns.
Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.
