ID Expansion Clamps

Jergens, Inc
Jergens ID Expansion Clamps are the ideal way to hold parts on an inside diameter for multiple machining on a vertical or horizontal machining center. The larger diameter of the clamp is held to a close tolerance for precision locating in a machined pocket on work cubes and fixture plates. The customer machines the mild steel clamp to match the bore of the part, ensuring a proper fit. Often the clamps can be machined again for different size jobs.

Features, Benefits, & Product Specifications:
  • Body Material: Mild Steel
  • Low profile
  • Ideal for secondary operations on lathe parts
  • Easily machined to size on lathe or mill
  • Excellent for palletized setups
  • Allows more parts per work cube or fixture plate
  • Tighten with hex key or hydraulic pull cylinders (Drill clearance hole for longer bolt into the hydraulic cylinder)
  • Instructions included with each clamp

Note(s):
  • For “H” dimension: (3) Mounting Screws included.
  • The “G” dimension is the mimimum diamater the “F” dimension can be machined to.
