- high clamping power without clamping cylinder
- clamping via disk springs
- unclamping via compressed air
- permanently connected supply ring for compressed air
- fatigue-proof clamping
- for drawback collets
- simple mounting
- for internal clamping too
Because of clamping via disk springs the chuck is always clamped, so the chuck is self-locking. For unclamping compressed air is required. 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 device must be provided.
