bearing cage FDC

bearing bearing cage FDC3809A is the same as DC3809A,but the torque is more higher than DC3809A,And low noise.

  Sprag type bearing cage FDC

1. Type  FDC  are the sprag type freewheel cage without inner or outer races. Its model and construction is followed for, this type provides higher torque and lower noise while fixed convenient.

 2. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing.

3.Alternatively, races can be made in case hardened steel shafts, or housings, to the specification below.

4.Surface hardness of the finished pargt should be HRC 60 to 62°, for a depth of 0.6mm minimum.

5.Core hardness to be HRC 35 to 45°. Surface roughness not to exceed 22CLA . Maximum taper between races:0.007mm for25mm Width.
