48A020 - Walter 48-A-020 Replacement Gearbox Housing Assembly

Restore Your Tool's Performance with Genuine Walter Parts

The Walter Gearbox Housing Complete (SKU: 48A020) is an essential replacement component designed to maintain the structural integrity and mechanical efficiency of your Walter power tools. In the demanding world of industrial metalworking, angle grinders and power tools are subjected to intense vibration, heat, and mechanical stress. Over time, the gearbox housing—which serves as the critical protective shell for your tool's transmission—can suffer from wear, cracks, or impact damage. Replacing a compromised housing is vital not only for the tool's performance but also for operator safety.

This genuine OEM part is manufactured by Walter Surface Technologies to the exact specifications of the original equipment. It is cast from a durable metal alloy specifically chosen for its strength-to-weight ratio and thermal conductivity. A healthy gearbox housing effectively dissipates the heat generated by high-speed gears, preventing overheating and extending the life of internal bearings and pinions. By choosing the authentic 48A020 part, you ensure that all internal components align perfectly, reducing noise and vibration during operation.

Installation of the Gearbox Housing Complete restores the protective barrier against shop dust, metal shavings, and other contaminants that can destroy sensitive gearing. Whether you are repairing a tool that has been dropped or refurbishing a unit that has seen years of heavy service, this housing provides the factory-fresh fit required for reliable operation. Trust in Walter's engineering to keep your production lines moving and your tools in peak condition.

Key Benefits:

• Exact Fit: Designed specifically for compatible Walter tools, ensuring no modification is needed during assembly.
