How to Select a Sprag Clutch Bearing

Operating Conditions

• Load capacity (torque and radial loads)

• Rotational speed (maximum RPM)

• Working temperature range

• Presence of shock loads or vibrations

• Lubrication method (oil lubrication or dry lubrication)

Size Specifications

• Shaft diameter (inner diameter) and outer diameter

• Bearing width

• Choose dimensions according to available installation space

Load Capacity and Durability

• Select a bearing with a rated load capacity suitable for your torque and usage frequency

• Prefer bearings made of high-quality materials with good fatigue life and wear resistance

Installation Method

• Confirm if the bearing’s installation structure matches your machinery

• Check if any bearing housing or seat is required

Rotation Direction and Locking Function

• Confirm the sprag clutch locks in the required rotational direction (clockwise or counterclockwise)
