Dynabrade 11343 Contact Wheel 5/16 in Crowned 50 Duro Rubber

Product Description

The DYNABRADE 11343 is a small-diameter contact wheel designed for use with Dynafile abrasive belt tools. The wheel measures 5/16 inches in diameter and 3/8 inches wide, with a crowned surface profile that helps center the abrasive belt and maintain consistent edge contact during filing and deburring operations. The face is constructed from 50 durometer rubber, which provides controlled compliance against the workpiece without excessive deflection. At 1 pound, it is a lightweight component suited for precision finishing work. Metalworking shops, fabrication facilities, and maintenance technicians typically install and service these wheels during routine abrasive tool maintenance.

This contact wheel fits applications where tight-radius or detail finishing is required, such as weld seam blending, deburring of small bores, and contouring on metal or composite surfaces. The 50 duro rubber face is appropriate for general-purpose stock removal and finishing passes on ferrous and non-ferrous metals. The crowned surface geometry helps track narrow abrasive belts consistently, reducing belt wander during extended use on Dynafile-style inline pneumatic filing tools.

Installation Notes

Contact wheel replacement on pneumatic abrasive belt tools should be performed by a qualified technician with the air supply fully disconnected before disassembly. Verify that the replacement wheel diameter and durometer rating match the tool manufacturer's specification before installation. Inspect the abrasive belt for proper tracking alignment after installing a new contact wheel before returning the tool to service.
