De-sta-co 821556 Swing Clamp Arm Blank Aluminum

Product Description

The DE-STA-CO 821556 is a blank swing clamp arm machined from aluminum, designed for use with pneumatic and hydraulic swing clamp bodies in fixture and workholding applications. The arm measures 1.5 inches overall length with a 0.75 inch width, and adjusts to clamping heights ranging from 0.37 to 0.75 inches. The 1/4-20 port thread accepts standard accessories and custom tooling pads. The blank arm profile gives toolmakers and fixture builders a clean starting surface for secondary machining, allowing custom tip geometry or contact pads to be added to suit the specific workpiece. This part is installed by tooling engineers, fixture designers, and skilled maintenance technicians in manufacturing environments.

This swing clamp arm is used in production fixtures on machining centers, welding cells, and assembly stations where repeatable part location and clamping are required. The blank configuration is common in custom fixture builds where the contact point must be tailored to a specific part geometry. Typical installations involve replacing a worn or modified arm, or configuring a new swing clamp body for a unique workholding setup. The aluminum construction keeps moving mass low, which is relevant in high-cycle automated fixtures.

Installation Notes

Installation is performed by tooling engineers or maintenance technicians. Before replacing a swing clamp arm, shut off and lock out all pneumatic or hydraulic supply lines to the clamp body per applicable LOTO procedures. Confirm port thread engagement is complete and the arm is seated correctly against the clamp body before returning the fixture to service. Secondary machining of the blank arm should be completed before installation.
