Heavy Duty Excavator Angular Contact Ball Bearing
✔️ Single bearing, 289 mm bore, 355 mm OD, 33 mm thick, open cage

This single row angular contact ball bearing arrives loaded as one complete unit for fast excavator rebuilds. Machinery operators typically seat it inside main slew rings where the drive needs steady support against combined axial and radial loads.

✅ Precise inner circle measures 289 mm for direct shaft engagement
✅ Outer diameter stretches 355 mm to fit common excavator housings
✅ Thirty three millimeter width keeps overall footprint compact
✅ Slanted oil groove pumps lubricant straight into the rolling elements
✅ Free opening style allows easy greasing without special covers

💡 How does precise angular contact geometry help heavy equipment swing mechanisms turn smoothly? Swapping worn rotary parts out for this setup is pretty handy when you want to cut down on unexpected downtime. The tilted load path directs lateral forces straight into the hardened rings so the track stays centered. - High torque resistance maintains consistent movement even when pulling full buckets sideways - Reduced friction surfaces lower operating temperatures during extended digging shifts - Efficient grease channels through the slanted raceway keep internal components clean longer
