BEARING - BALL SINGLE SHIELD (Komatsu KO300666-012)

KO300666-012: A worn ball bearing can cause shaft misalignment and premature equipment failure. The Komatsu catalog reference KO300666-012 identifies this aftermarket replacement part. This single-shield bearing reduces friction between rotating components while protecting the internal race from debris. A failed bearing often produces audible noise and vibration before seizing completely. In continuous-operation settings, bearing degradation accelerates without regular inspection. This item ships at approximately 0.214 pounds. Verify the serial number or application, then call (562) 693-7748.
