Stieber Sprag Clutch Bearing Roller Type Freewheel Non-Bearing Supported 12 mm ID 35 mm OD 13 mm Race Width ASNU 12

Stieber ASNU 12 sprag clutch bearing is a precision roller type freewheel, non-bearing supported component with a 12 mm inner diameter, 35 mm outer diameter, and 13 mm race width. It requires external bearings for axial and radial load support, with lubrication and sealing also provided by the installation. Typically, it is installed alongside a bearing within the same location tolerances.

The inner race is keyed directly to the shaft, ensuring secure torque transfer. The outer race has a positive n6 tolerance, permitting a press fit in a housing with H7 tolerance. Additional side notches in the outer race offer positive torque transmission in housings with a K6 tolerance, though use of these notches is optional if the housing strength is adequate to avoid expansion after assembly.

This type of sprag clutch bearing is engineered to accept an axial misalignment between inner and outer race of ± S/2, enhancing installation flexibility. Compliance with DIN 6885.3 and DIN 6885.1 standards ensures the reliability and dimensional accuracy required for industrial machinery, fluid power, and mechanical applications.

Stieber sprag clutch bearings are extensively used in industrial environments such as manufacturing equipment, conveyors, and automation systems where reliable roller freewheel and torque transmission are critical.

The inner race keyed to the shaft provides secure torque transfer. Outer race positive n6 tolerance supports a press fit in H7 housings. Additional notches enable torque transmission in K6 tolerance housings. Accepts axial misalignment of ± S/2 to accommodate installation variances.

Requires external bearings for axial and radial load support. Designed for industrial and mechanical engineering applications. Explore more high-quality rotary bearing solutions and Sprag Clutch Bearings at EnvMart for your industrial and machinery needs.
