Installation and Usage

1. The outer race of the TFS Series Cam Clutch was designed for press fit installation to the housing. Correct interference dimensions of the outer race must be maintained to option maximum clutch performance. The internal diameter for the housing should meet the H7 tolerance of the JIS standard. Keyways should be made in the end faces of clutch for proper installation. Refer to item 3 in the installation and usage for CSK. Series Cam Clutches 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 bearings inside.
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
1.Oil lubrication is recommended.
2. Do not use greases or lubricants with EP additives.
