Bearing Blaster (RPM81170)

The Bearing Blaster, often referred to as the RPM Bearing Blaster, is a compact two-piece cleaning tool designed to blast away debris from bearings and extend their life. It works with pressurized cleaners that have a directional spray tube—such as Motor Spray, WD-40, or electrical contact cleaner—and uses hand pressure to hold the bearing in place for quick, controlled cleaning.

Its open flow-through design minimizes back-pressure and helps flush dirt and grit from bearings more efficiently. The tool supports bearings with an inner diameter as small as 1/8" (3 mm) and an outer diameter up to 3/4" (19 mm), and it stands about 1-1/8" tall and 1-3/4" in diameter. This compact, hand-held device keeps cleaning fluid directed through the bearing, making the process faster and more thorough for small bearing maintenance tasks.
