Bull
The pneumatic automation vise! With our pneumatic high-pressure clamping system, the Bull Pneumatic, series production can be brought up to full speed.
- For automation and high-performance series production
- High clamping force at just 6 bar compressed air due to the integrated pressure intensifier
- No hydraulic unit required

Because 40 kN of maximum clamping force equips the Bull as an optimal clamping system for robotic loading. The Bull also ensures accurate and precise parts with its pull-down clamping system. No tedious cranking, as the patented clamping range adjustment allows for very quick adjustment of the clamping range. Clamping without effort!

FAQ – frequently asked questions
The detent lugs on the spindle of the Bull Pneumatik machine vise can be manually rotated 180° downwards.
After that, the movable jaw can be shifted and locked in the desired position.
The approach to approximately 1 mm from the workpiece is done with the supplied hexagon key.
Compressed air is only needed for clamping with the Bull Pneumatik machine vise.
Opening occurs via a spring return integrated into the spindle.
Compressed air can be connected either at the front or side of the connection cover (G1/8" thread).
The Bull Pneumatic machine vise can be supplied with block jaws or step jaws and optionally with a 3.5 mm or 5 mm clamping stroke.
Thus, 4 variants are available.
By installing a check valve in the compressed air line, a drop in clamping force is prevented.
With the pull-down clamping system of the Bull Pneumatik, forces are only partially transmitted through the base body.
This minimizes deformation, and the accuracy of the machined workpiece is increased.
