48Q266 - Walter 6001 RS Replacement Bearing

Precision Engineering for Industrial Reliability

The Walter 48Q266 Ball Bearing 6001 RS is a critical component designed to restore the optimal performance of Walter Surface Technologies power tools. As a fundamental element in rotational machinery, the quality of a bearing directly influences the run-out, vibration levels, and overall longevity of the equipment. This specific unit adheres to the 6001 series standard dimensions—12mm inner diameter, 28mm outer diameter, and 8mm width—ensuring a precise interference or clearance fit depending on the specific assembly requirements of the tool housing and shaft.

Constructed from high-grade bearing steel, the 48Q266 is engineered to withstand the radial and axial loads typical of handheld abrasive power tools. The "RS" designation indicates the presence of a rubber seal on one side of the bearing. This seal is paramount in industrial environments, particularly in metalworking and welding shops where conductive dust, metal shavings, and abrasive grit are prevalent. The seal acts as a barrier, preventing these contaminants from entering the raceways and degrading the lubricant, while simultaneously retaining the factory-applied grease. This design choice balances friction reduction with contamination control, optimizing the bearing for the high-speed operation characteristic of grinders and finishing tools.

Utilizing genuine OEM parts like the 48Q266 ensures that maintenance procedures maintain the tool's original safety and performance ratings. Generic bearings may lack the specific tolerance classes or internal clearance (e.g., C3) required for the thermal expansion experienced during prolonged tool use. By selecting the Walter 48Q266, maintenance engineers and technicians can be confident in the component's compatibility and reliability, minimizing downtime and the risk of premature failure in critical production assets.

Technical Specifications and Fitment

This deep groove ball bearing is versatile yet specific in its application within the Walter product line. Its geometry is optimized for low noise and low vibration, which is essential for operator comfort and precision finishing. The single-row design allows for robust performance at high RPMs, making it suitable for the drive trains of electric motors found in surface finishing equipment. Installation should always be performed with proper pressing tools to avoid brinelling the raceways or damaging the seal.
