1、Type FDC is a sprag type freewheel cage without inner or outer races. It’s 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、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.
4、We can offer standard inner and outer races, as shown on the following pages.
5、Alternatively, races can be made in case hardened steel shafts, or housings, to the specification below.
6、Surface hardness of the finished pargt should be HRC 60 to 62°, for a depth of 0.6mm minimum.
7、Core hardness to be HRC 35 to 45°. Surface roughness not to exceed 22CLA . Maximum taper between races:0.007mm for25mm Width.
2)Inner race overruns
3)Outer race overruns
**)Extension of tolerance to ±0.013 Permissible Other dimensions on request NO, of drag strip and clips may be produced on regnest
Use 2 # lithium grease 30% + Engine oil 70% , Stirring evenly. grease the required temperature range -40 ℃ ～+ 150 ℃. Plus grease once for every month.
