SMG: Specially designed for gripping small components

The most cost-efficient choice in the electronic light assembly industry.

SMG can provide standard solution for many fields of application. Gripping and moving small workpieces in low-pollution environments such as assembly, testing, laboratory and electronic automation industries.  

Advantages – Your benefits

  • Function optimized gripper type for maximum cost effectiveness
  • Stable, ground T-groove slideway for highest precision in handling different workpiece Wedge-hook design for high power transmission and synchronized gripping
  • Large gripping force and bearing capacity
  • Small size, light weight
  • Proximity switches can be installed to detect the opening and gripping of pneumatic gripper for maximum process reliability
  • Mounting from two sides for universal and flexible gripper assembly

Functional description

  • The round piston is pushed upwards or downwards with compressed air.
  • The angled active surfaces of the wedge-hook produce a synchronized, parallel jaw motion.
  1. Base Jaw
    for the connection of workpiece-specific gripper fingers
  2. Wedge-hook design
    for high force transmission and centric gripping
  3. Drive
    pneumatic piston drive
  4. Housing
    is weight-optimized due to the use of aluminum alloy
