Installation and Usage
1. The outer race of the TFS Series Cam Clutch is designed for press fit installation to the housing. Correct
interference dimensions of the outer race must be maintained to obtain maximum clutch performance.
The internal diameter of the housing should meet the H7 tolerance. Keyways should be made in the end faces
of the clutch for proper installation. Refer to item 8 in the installation and usage of BB Series Cam Clutch for
information on the installation method. If the tolerance of the internal diameter of the housing is K6, keyways
are not required on the end faces of the clutch.
2. Make sure the housing has enough strength to withstand the pressure required for the press fitting installation
of the clutch.
3. When installing the clutch, mount it with a type 63 bearing to avoid radial force, since this clutch does not have
any bearing support.
4. The clutch should be mounted on the shaft by rotating it in the direction marked by the arrow shown on the
clutch plate.
5. The recommended shaft tolerate is h7, and the key profile
should be in accordance with the following standard.
TFS 12 ······DIN 6885. 1
TFS 15 ~ 80······DIN 6885. 3
6. Suitable surface pressure of the key should be selected
according to your company design standards.
Lubrication
