3304 A-2Z/C3MT33 SKF Angular Contact Ball Bearing 20mm x 52mm x 22.2mm
3304 A-2Z/C3MT33 SKF Angular Contact Ball Bearing 20mm x 52mm x 22.2mm
This premium double row angular contact ball bearing from SKF is engineered to deliver reliable performance in applications requiring simultaneous radial and axial load handling. The 3304 A-2Z/C3MT33 combines robust construction with protective sealing, making it an excellent choice for industrial machinery, gearboxes, and precision equipment operating in moderately demanding environments.
Design & Construction
The double row configuration provides enhanced load carrying capacity compared to single row designs, while the strategic raceways enable efficient handling of complex loading conditions. The slightly increased radial clearance allows for stable operation with temperature fluctuations and varying load conditions.
- Double row design for superior load carrying capacity and rigidity
- 30° contact angle optimized for balanced radial and axial load distribution
- Sheet steel cage construction for reliable ball retention and durability
- 2Z seals (covers on both sides) provide protection against contamination while maintaining accessibility
- Slightly increased radial clearance for flexibility in mounting and temperature variations
- Standard bearing steel construction for strength and extended service life
- Outer ring without flange or groove for flexible installation options
