Dynabrade 15027 Contact Arm 1/8 Inch Rubber Crowned

Product Description

The DYNABRADE 15027 is a replacement contact arm designed for use with abrasive belt tools in professional grinding, finishing, and deburring applications. This contact arm features a rubber contact wheel measuring 5/8 inch in diameter and 1/8 inch in width, with a crowned wheel face surface and a 70 durometer rubber compound. The crowned profile helps maintain consistent belt tracking and even pressure across narrow contact areas. At 0.01 pounds, the assembly is lightweight and engineered for precise fitment into compatible contact arm assemblies. This part is intended for technicians and fabricators who service or rebuild abrasive belt tool systems.

This contact arm is suited for narrow-profile finishing work where a 1/4 inch belt width is used. The 1/8 inch wide crowned rubber wheel is appropriate for detail grinding, contour finishing, and edge work on metal or similar materials. It is typically found in production shop environments, tool repair operations, and maintenance settings where abrasive belt tools require periodic component replacement to maintain performance.
