Item Details
- The Dynabrade 11239 is a heavy-duty contact arm assembly designed for industrial pneumatic abrasive belt tools. It serves as a high-durability replacement and modular upgrade for standard arms, specifically engineered to guide and track narrow abrasive belts in high-pressure production environments. This assembly is the heavy-duty version of the 11213 arm and features a full steel construction to prevent deflection during aggressive stock removal.
Features
- Heavy-duty steel arm bar construction to minimize bending and twisting under leveraged force
- Solid steel contact wheel for zero surface compliance and maximum grain penetration
- Precision-crowned wheel face for automatic belt centering and tracking
- Integrated 1/2 inch wide thin platen pad for flat grinding and surface profiling
- Industrial-rated for continuous multi-shift production line usage
- Compact profile for access to restricted channels, deep slots, and acute corners
- Heat-resistant metallurgy to maintain tolerances during prolonged metal-on-metal grinding
- Sealed internal bearings to prevent lateral belt wandering at high surface speeds
- Modular compatibility with 11739 Adapter for extended 8-inch reach
