48Q264 - Walter 608-2RS Sealed Ball Bearing Replacement

Precision Engineering for Industrial Tool Maintenance

The Walter Ball Bearing 608 2Rs (SKU: 48Q264) is a critical component designed to restore the performance and precision of your industrial power tools. In the realm of MRO (Maintenance, Repair, and Operations), the integrity of rotating assemblies is paramount. This specific bearing belongs to the widely utilized 608 series, a standard size found in a vast array of electric motors, angle grinders, die grinders, and finishing tools. However, not all 608 bearings are created equal. As a genuine Walter Surface Technologies replacement part, this component is manufactured to meet the rigorous tolerances and material specifications required by high-performance Walter tools.

The "2RS" designation indicates that this bearing features two rubber seals—one on each side of the race. This is a crucial specification for industrial environments. Unlike open bearings or metal-shielded variants (ZZ), the rubber seals provide a tight contact barrier that effectively prevents the ingress of microscopic contaminants. In metalworking and surface finishing applications, the air is often filled with abrasive dust, metal shavings, and grinding residue. If these particles penetrate the bearing race, they act as a grinding compound, rapidly destroying the ball bearings and raceways, leading to noise, heat, and eventual seizure. The 2RS seals on this Walter bearing ensure that the internal lubrication stays in and contaminants stay out, significantly extending the service life of the repair.

Technically, this single-row deep groove ball bearing measures 8mm in inner diameter, 22mm in outer diameter, and 7mm in width. It comes pre-lubricated with a high-grade grease suitable for the high RPMs and thermal loads experienced during heavy grinding or cutting operations. Whether you are rebuilding a tool's armature, replacing a spindle bearing, or performing preventative maintenance on your shop's equipment fleet, using genuine OEM-quality bearings like the Walter 48Q264 ensures that your tools operate with the smoothness and balance intended by the manufacturer.
