165x210x52 Angular Contact Excavator Ball Bearing

165mm Angular Contact Ball Bearing For Heavy Excavator Units
✔️ Inner 165mm Outer 210mm Width 52mm Double Row Open Nylon Cage

This 165 mm angular contact bearing supports heavy rotation loads in construction equipment. It features slanting oil grooves to manage lubrication efficiently during operation.

✅ Double row design allows higher radial capacity ✅ Nylon cage reduces friction while maintaining stability ✅ Open closure type permits standard grease filling

💡 How do angular contact bearings handle axial loads? These units align well with forces pushing along the shaft axis. - Internal contacts angle force toward inner ring for stability - Steel balls roll smoothly between groove surfaces under pressure - Proper maintenance keeps performance reliable over long operating hours
