48Q270 - Walter 48-Q-270 Replacement Ball Bearing 6802RS

Keep Your Walter Tools Running Smoothly

There is nothing worse than a grinder screaming at you or seizing up right in the middle of a job. If your Walter power tool has started making excessive noise, vibrating heavily, or overheating, it might be time to check the bearings. The Walter Ball Bearing 6802Rs (Part Number 48Q270) is the factory-correct replacement part you need to get your gear back in fighting shape. Don't settle for cheap, generic bearings that might not handle the RPMs or the dust—stick with the parts designed for your machine.

This bearing is a 6802RS type, which means it is a deep groove ball bearing with a rubber seal. That seal is the MVP here. In a welding or fabrication shop, the air is filled with grinding dust, metal shavings, and flux fumes. If that junk gets inside the bearing races, it acts like sandpaper, destroying the bearing in no time. The rubber seal on the 48Q270 is designed to keep the lubricant in and the shop grime out, ensuring your tool spins freely and lasts longer. It measures 15mm x 24mm x 5mm, a common size for armatures and internal assemblies in compact power tools.

Replacing a worn bearing is a smart maintenance move that saves you money in the long run. A bad bearing puts extra load on the motor, which can burn out the brushes or the windings, turning a cheap repair into a total tool replacement. By swapping in a fresh Walter 48Q270 bearing, you restore the smooth operation of your grinder or sander, reducing hand fatigue caused by vibration and ensuring your cuts and finishes remain precise.

Whether you are a shop foreman maintaining a fleet of tools or a fabricator fixing your favorite grinder, this part is essential. It’s built to take the heat and speed of professional work. Grab a few for your spare parts drawer so you are never down for long when a tool needs a tune-up.
