Introduction of DC series Sprag Type One Way Freewheel Clutch Bearing
1.Type DC is a sprag type freewheel cage without inner or outer races. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing.
2.The DC type version-N accepts all types of lubricants currently used in the power transmission equipement.
3.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 the freewheel functions correctly .
4.Alternatively, races can be made in case hardened steel shafts, or housings, 
Surface hardness of the finished part should be HRC 60 to 62, for a depth of 0,6 mm minimum.
5.Core hardness to be HRC35 to 45. Surface roughness not to exceed 22CLA. Maximum taper between races:0,007 mm for 25 mm width.
