MM-BI Pneumatic fastening clamps for axial locking

The pneumatic fastening clamps (Misati patent) are used for locking mechanical parts to be processed or handled on jigs and brackets.
The fastening clamps are characterised by “a double effect” pneumatic cylinder which transmits a rotating movement to the clamping arm.

The main features:
• high clamping force;
• reduced size;
• low consumption of compressed air;
• reduced weight.

The clamping arm movement has been designed so that, once the locking position is reached, a self-maintenance situation is obtained.

The clamping arm stroke is fast initially but then slows down prior to final clamping; so, usually, the installation of a pneumatic cushioning is not required. However, in case the standard accessories supplied do not satisfy the application requirements, it is possible to provide the fastening clamp with a cushioning as a special execution on request.

The clamping mechanism consists of two rolling bearings ensuring optimal clamping torques and minimal wear.

The hole positions for the pneumatic connections are at the base of the cylinder to keep connecting tubes clear of the work area.

The position of the mounting holes made on the monobloc body of the pneumatic fastening clamps has been provided so as to allow installation directly on threaded holes or alternatively on plain pass-throught holes by means of bolts.

The cylinders of diameter 20, 32, 40, 50 mm develop a tightening momentum between 60 Nm and 475 Nm, values higher than similar products on the market.
Under specific stress resistance tests, these fastening clamps showed constant performance for more than 20 million cycles.
