- mechanical power transmission
- high clamping power
- hardened and ground housing
- constant clamping force
- fatigue-proof clamping
- full spindle capacity as the clamping cylinder is integrated in the chuck
The mechanical power transmission is designed in a way that, when clamped, the chucks are self-locking. The self-locking device only operates within a small range. For this reason, only workpieces within range of tolerance group IT 9 can be clamped safely. Due to the self-locking device, compressed air is required for clamping and release.
Type PSF for operation with a compressed-air gun
The chuck has two holes into which compressed air can be fed from a compressed-air gun for clamping and release. After the clamping procedure the chuck remains clamped.

Type PSF-SR rotating collet chucks with supply ring
These chucks are equipped with a permanently connected supply ring and sealing through which the compressed air is applied during clamping and unclamping. Clamping can only take place with the spindle stationary as the seal lies on the chuck body and produces a high degree of friction. For safety reasons an appropriate protective device must be provided.
