Dynabrade 15326 Contact Arm 7/8 in Crowned Rubber Wheel

Product Description

The DYNABRADE 15326 is a contact arm designed for flat grinding applications using a platen pad. It features a 7/8 inch wide crowned rubber contact wheel with a 3/4 inch diameter, providing consistent belt-to-workpiece contact on flat surfaces. This component is used with a belt sander or abrasive belt finishing tool and is installed as part of a contact arm assembly. Licensed tool and die makers, metal fabricators, and industrial maintenance technicians typically install this part when replacing worn or damaged contact arms on compatible DYNABRADE belt finishing equipment.

This contact arm is suited for precision flat grinding and surface finishing in metal fabrication, tooling, and maintenance environments. It is configured for use with a 24 inch belt length and 1 inch belt width, making it appropriate for benchtop and handheld belt finishing tools in both production and job-shop settings. The crowned wheel face is designed to maintain even belt tracking and pressure distribution across flat workpiece surfaces.

Installation Notes

Installation is typically performed by a trained tool and die maker, maintenance technician, or industrial equipment service professional. Always power down and disconnect the abrasive belt tool from its air supply or electrical source before replacing the contact arm. Verify belt width and length compatibility before installing to prevent belt tracking issues or premature wear. Follow the tool manufacturer's service documentation for assembly torque and alignment procedures.
