Function description

180 angular grippers (radial grippers) are advantageous in that they save an additional stroke movement. Since each jaw rotates away by 90, they are mostly removed from the work area; a stroke movement to retract the entire gripper can be omitted.
Options and special information
Monitoring with a SCHUNK MMS 22 or RMS 22 sensor is not possible. The use of the recomended sensors MZN and RZN is not compulsory.

Accessories

Gripping moment is the arithmetic total of gripping moments for each claw jaw. Finger length The finger length is measured from the upper edge of the gripper housing in direction to the main axis. If the max. admissible finger length is exceeded, the speed of motions of the jaws has to be reduced and/or the opening angle has to be diminished, as it is done with heavy fingers. The service life of the gripper can shorten. Repeat accuracy is defined as the spread of the limit position after 100 consecutive strokes. Workpiece weight The recommended workpiece weight is calculated for a force-type connection with a coefficient of friction of 0.1 and a safety factor of 2 against slippage of the workpiece on acceleration due to gravity g. Considerably heavier workpiece weights are permitted with form-fit gripping. Closing and opening times Closing and opening times are purely the times that the base jaws or fingers are in motion. Valve switching times, hose filling times or PLC reaction times are not included in the above times and must be taken into consideration when determining cycle times.

Moments and forces apply per base jaw and may occur simultaneously. My may arise in addition to the moment generated by the gripping force itself. If the max. permitted finger weight is exceeded, it is imperative to throttle the air pressure so that the jaw movement occurs without any hitting or bouncing. Service life may reduce.

Main views

The drawing shows the gripper in the basic version with closed jaws, the dimensions do not include the options described below. The SDV-P pressure maintenance valve can also be used (see Accessories catalog section) for I.D. or O.D. gripping as an alternative or in addition to the spring-loaded, mechanical gripping force safety device.
