Introduction

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

power transmis-sion equipement.
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

 as shown on following pages.
Alternatively, races can be made in case hardened steel shafts, or housings, to the 

specification below. Surface hardness of the finished part should be HRC 60 to 62, 

for a depth of 0, 6 mm minimum.
Core hardness to be HRC35 to 45. Surface roughness not to exceed 22CLA. Maximum
