Stieber Sprag Clutch Bearing 30 mm ID 72 mm OD 27 mm Race Width ASNU 30

Stieber ASNU 30 sprag clutch bearing is a precision mechanical component designed for freewheel rotary applications. This bearing features a 30 mm inner diameter (ID) and a 72 mm outer diameter (OD) with a 27 mm race width, making it suitable for installations requiring accurate torque transmission and axial/radial load support.

The ASNU 30 model employs a roller type freewheel mechanism and is non-bearing supported; therefore, it necessitates installation alongside bearings that provide axial and radial load support, lubrication, and sealing. The inner race is precisely keyed to fit the shaft, while the outer race features a positive n6 tolerance that allows a press fit in an H7 housing. Side notches on the outer race assist in positive torque transfer, especially when the housing tolerance is not to K6 specification.

This bearing is engineered to tolerate an axial misalignment between the inner and outer races up to ± S/2, enhancing its versatility and reliability in dynamic mechanical environments. The design complies with DIN 6885.3 and DIN 6885.1 standards, ensuring industry-accepted quality and performance.

Typical industrial applications include use in mechanical machinery assemblages, rotary drives, and power transmission systems demanding precise clutching action and minimal backlash.
