Accessories

Brief description

The RUWI eccentric clamp secures your workpiece using an eccentric lever on the 20-mm hole pattern—a single lever movement instead of a screw, with no tools required. You can position it freely using the plate with the elongated hole and secure it in any 20-mm hole using the clamping bolt and washer.

The eccentric itself is made of plastic (POM)—it clamps securely without scratching delicate surfaces. The plate is made of galvanized steel (180 × 40 mm), the clamping bolt is made of stainless steel, and the swivel bearing is burnished. This makes the clamp ideal for production work and fixtures where you need to quickly clamp and release many parts.

The vertical clamp secures the workpiece from above, while the horizontal clamps secure it against a stop on the side; the positioning bracket serves as a fixed counterhold. You can find additional clamping accessories in the lift table system. For welding tables with a Ø28 or Ø16 hole pattern, the eccentric clamp for welding tables is available.
