Grippers

BLQ-E

BLQ-E is a pneumatic rubber expansion gripper for external grip — capable of gripping objects up to 40% larger than the gripper’s deflated diameter, ideal for gentle handling of delicate parts.

Models

BLQ-E is a pneumatic rubber expansion gripper for external gripping. Its structure allows each model to handle a large number of shapes by inflating around the workpiece.

Advantages

  • Multiple part sizes handled with one gripper, thanks to its capability to grip an object up to 40% larger than the gripper’s deflated diameter.
  • Light handling by controlling the pressure inside the gripper.
  • Force distribution over a wide surface allows delicate yet secure gripping even with heavy loads.
  • Particularly suitable for gripping glass and plastic objects — the type of contact does not damage the workpiece.
  • Wide range of sizes for objects from 5 to 105 mm diameter.
  • Does not require lubrication.
  • Long service life even in dusty environments thanks to absence of seals or bearings.
