BK320KQ | 320 mm 3-Jaw Semi-Through-Hole Pneumatic Chuck product image

The TOP-TOOL BK320KQ is a 320 mm 3-jaw semi-through-hole pneumatic chuck for applications requiring partial rear clearance while retaining a compact air-operated chuck structure.

The semi-through-hole design provides additional clearance for suitable workpieces without using a full through-hole structure. Confirm the workpiece geometry and required clearance before ordering.

Key Features

  • Air-operated clamping for repeatable loading and unloading cycles.
  • Through-hole or semi-through-hole structure for workpiece clearance.
  • Multiple chuck sizes available for different workpiece ranges.
  • Technical parameters are provided for model selection.

Typical Applications

  • Pneumatic workholding setups
  • Repeat loading and unloading operations
  • Machining applications requiring air-operated clamping
  • Model selection based on chuck size, gripping range and installation method

Selection Notes

  • Confirm the workpiece dimensions and required gripping range.
  • Check whether a solid, semi-through-hole or through-hole structure is required.
  • Review the allowable air pressure, jaw stroke, clamping force and maximum speed.
  • Send the machine information and workpiece drawing for technical review before ordering.
