STEVENS Chain Vise Clamps

Stevens Engineering Chain Clamps are a unique way to hold any round work piece on a machining center. Use in combination with our Vee-Blocks to clamp a wide range of sizes.

Each Standard Duty Kit P/N 20149 (clamping force up to 6,000 lbs) includes a cam-locking hook assembly P/N 20150, a take-up unit P/N 20151 for adjusting chain tension, and a chain set P/N 20152. Any length chain up to 40 inches can thus be quickly assembled for various workpiece diameters.

Each Heavy Duty Kit P/N 20149HD (clamping force up to 12,000 lbs) includes a cam-locking hook assembly P/N HD20150, a take-up unit P/N HD20151, and a chain set P/N HD20152. The heavy duty kit includes 64 inches of chain.

Features:

• Fast initial setup. Socket head cap screws are used for mounting each end of the chain clamp to a subplate or T-slotted table.
• Additional lengths of roller chain may be added for holding extra large workpieces.
• Since workpiece sizes vary, differing lengths of chain may need to be assembled. Hitch pins are included in the kit and are used to assemble varying lengths of roller chain to fit different workpiece sizes. Hitch Pins which replace spring clips allow quicker and easier assembly & disassembly of chain sets.
• Plastic shoes P/N 10421 or 10421HD snap into chain to protect finished surfaces.
• Five pieces per package.
• One package is included in chain clamp assembly.
• The Modular fixture above utilizes two chain clamps to secure the valve body casting. A standard Allen wrench is used to operate the cam-locking hook assembly.
