48M775 - Walter Grinder Replacement Bevel Gear and Pinion Set

Precision OEM Replacement Gearing

The Walter 48M775 Bevel Gear W/Pinion is a critical replacement component designed to restore the functionality and performance of specific Walter Surface Technologies angle grinders. In the high-stress environment of industrial grinding and finishing, the gearbox of a power tool is subjected to immense torque, heat, and mechanical stress. Over time, the teeth of the bevel gear and pinion can wear down, chip, or deform, leading to a loss of power transmission, increased vibration, and excessive noise. This genuine OEM set is manufactured to the exact tolerances required by Walter's engineering standards, ensuring a seamless fit and optimal operation.

Constructed from high-grade hardened steel, these gears are heat-treated to withstand the rigorous demands of heavy-duty metalworking. The set includes both the larger bevel gear (crown gear) and the smaller pinion gear. It is standard engineering practice to replace these components as a matched pair. Because gears "bed in" together during their service life, introducing a new gear to run against an old, worn gear can result in rapid failure, poor meshing, and potential damage to the grinder's bearings or motor. By installing the 48M775 set, maintenance professionals ensure that the tool's transmission geometry is reset to factory specifications.

The precision machining of the gear teeth ensures smooth engagement, which is vital for maintaining the high RPMs associated with Walter grinders. Proper gear meshing reduces friction and heat buildup within the gear head, prolonging the life of the lubricant and the surrounding components. When servicing a Walter tool with this part, it is highly recommended to clean out old grease and debris from the gear housing and apply the manufacturer-specified amount of fresh, high-quality gear lubricant. This attention to detail during the repair process guarantees that the tool will continue to deliver the superior performance Walter users expect.

This component is essential for MRO (Maintenance, Repair, and Operations) cribs supporting fabrication shops that rely on Walter power tools. Keeping a spare gear set on hand minimizes downtime, allowing technicians to quickly repair tools that exhibit symptoms of gear failure, such as grinding noises or a seized spindle. Trusting genuine Walter parts like the 48M775 ensures equipment reliability and safety compliance in professional environments.
