Centric Gripper

General gripper Schunk

Schunk’s PZB-plus gripper features central bore and multi-tooth guidance.

Schunk introduced the PZB-plus, a 3-finger centric gripper series that features a central bore designed as a sleeve. The central bore, which is also equipped with female threads for customer-specific add-ons, can be used to supply material or as an ejector. It can also be used to monitor the handling or assembly process with a camera system or to pick up workpieces and centre them.

The series is available in two different stroke length versions, the smaller of which has approximately double the gripping force. The six sizes, from 64 to 200, are fitted with a multi-tooth guide, meaning the PZB-plus can handle 100 percent higher torques in directions at right angles to the gripping motion. An optional gripping force safety device is also available, which are spring loaded for ID or OD gripping. The position is monitored either via a magnetic switch or inductive proximity switch.
