Dynabrade 11073 Contact Wheel 5/8 in Crowned Rubber

Product Description

The DYNABRADE 11073 is a contact wheel assembly designed for use with Dynabrade belt grinders and abrasive belt tools. The wheel measures 5/8 inches in diameter and 1/8 inches wide, with a 1/8-inch arbor hole for secure spindle mounting. Its crowned face profile helps center the abrasive belt during operation, reducing edge wear and improving tracking consistency. The rubber face is rated at 70 durometer, which provides moderate hardness suited for controlled material removal on contoured or flat workpieces. This part is installed by metalworking professionals, tool-and-die technicians, and industrial maintenance mechanics who rely on precision abrasive finishing equipment.

This contact wheel assembly is used in abrasive belt finishing and grinding applications across industrial and manufacturing environments. The crowned surface geometry makes it appropriate for applications where belt self-centering is a priority, such as fine finishing on metal components, weld blending, and deburring operations. It is sized for compact Dynabrade pneumatic or electric file belt tools that accept a 1/8-inch arbor wheel. Typical installation environments include fabrication shops, tool rooms, and production finishing lines.

Key Features

• Crowned face profile aids abrasive belt tracking and centering during operation
• 70 durometer rubber face provides moderate hardness for balanced conformability and stock removal
• 5/8-inch diameter and 1/8-inch width suit compact belt file and finishing tools
• 1/8-inch arbor hole for direct spindle mounting on compatible Dynabrade tools
• Rubber face material resists heat buildup during continuous abrasive contact

Compatibility

Designed as an OEM-style replacement contact wheel assembly for Dynabrade abrasive belt tools that accept a 1/8-inch arbor wheel with a 5/8-inch diameter contact wheel.

Installation Notes

Installation is performed by qualified metalworking technicians or industrial maintenance personnel. Disconnect and lock out all power or air supply to the tool before removing or installing the contact wheel. Ensure the arbor nut is secured to the tool manufacturer's recommended procedure without over-tightening, which can distort the rubber face. Inspect the abrasive belt for proper tracking after installation before returning the tool to service.
