Self-adjustable model

Self-adjustable clamp model is a great option when the workpiece has irregular shapes.

These clamps have a self-adjustable ball pressure screw inserted into a clamp jaw.

The ball bearing at the end is made of steel and equipped with torsion protection, allowing the ball to self-adjust up to 9 degrees. This makes clamping irregular-shaped parts and castings more flexible.

Latest self-adjustable models (-‘E’) come with self-adjusting balls in both jaws.
