Product Knowledge: The Rotary Support Bearing 353-0490

The Rotary Support Ring Gear Bearing (Part 353-0490 / 3530490) is a large-diameter rolling-element bearing used in heavy machinery. For the CAT 345 and CAT 349, it typically consists of an inner ring, an outer ring (with internal or external gear teeth), and rolling elements (balls or rollers). The integrated gear teeth facilitate the rotation drive from the swing motor, making it a combined functional part. Proper lubrication and maintenance of the excavator slewing bearing are vital for longevity, preventing premature wear and operational failure on equipment like the CAT 345 Excavator Final Drive Parts.
