Cl = clamping, Uncl = unclamp
* Specifications with clamping arm, standard

Design:

Cylinder barrel from steel, hardened and burnished. Piston rod case hardened and chrome plated.
Piston rod with internal thread and clamping arm positioning. O-ring for flange seal.
Wiper at piston rod. Single acting version with return spring from stainless steel. Supply scope does not include clamping arm. Oil supply via threaded connection or oil channel in the fixture body.

Application:

The swivel clamp is used in fixtures in which the workpiece must be freely accessible and inserted from above. Even workpieces with difficult shapes can be clamped using special clamp arms (available on request).

Features:

The swing motion is executed via three ball guides, thereby increasing positioning accuracy, repeat accuracy and service life.

Note:

The piston stoke is executed with balls, respect Q max. volume flow. Clamping arm length and clamping arm weight must be strictly observed. When mounting accessories at the piston, no force may be applied to the piston. To equalise height differences on the workpiece, the vertical clamping path must be 50% of the clamping stroke. For single-acting cylinders, there is a risk of coolant being sucked through the breather port. In such cases the breather port has to be moved to a clean protected area via a connection line. When placing into operation, ensure that all air is bled from the system. Optionally, throttle non-return valve no. 6916-12-01 with G1/8 and 6916-12-04 with G1/4 can be used to throttle the oil supply. Other swivel angles are available on request.
