3218 FAG Double Row Angular Contact Ball Bearing 90mm x 160mm x 52.4mm
The 3218 FAG Double Row Angular Contact Ball Bearing is a robust precision bearing designed for demanding applications requiring simultaneous radial and axial load capacity. This versatile double row configuration delivers exceptional performance in high-speed, heavy-duty environments.
Design & Construction
Angular contact ball bearings feature angularly displaced raceways in both the inner and outer rings, enabling them to efficiently handle combined radial and axial loads. As a double row bearing, this design combines the capabilities of two single row bearings while maintaining a compact axial profile. Key advantages include:
- Accommodates axial loads in both directions
- Provides rigid, stiff bearing arrangements
- Capable of handling tilting moments
- Enhanced load carrying capacity compared to single row designs
- Optimised for high-speed operation
