STIEBER CLUTCH - DC Sprag Type

The DC type is a sprag type freewheel cage without inner or outer races. It must be installed in a design that provides races, bearing support for axial and radial loads, lubrication, and sealing. The DC type version-N accepts all types of lubricants currently used in power transmission equipment.

The sprag space tolerance must not be exceeded. Inner and outer races must both have a minimum plain width "e" without any recess to ensure that the freewheel functions correctly.

Alternatively, races can be made from case hardened steel shafts or housings to the following specifications:

• Surface hardness of the finished part should be HRC 60 to 62 for a depth of 0.6 mm minimum.

• Core hardness should be HRC 35 to 45.

• Surface roughness should not exceed 22 CLA.

• Maximum taper between races: 0.007 mm for 25 mm width.
