5309 S NTN Double Row Angular Contact Ball Bearing 45mm x 100mm x 39.7mm
5309 S NTN Double Row Angular Contact Ball Bearing
This robust double row angular contact ball bearing from NTN is engineered for demanding applications requiring simultaneous radial and axial load capacity with enhanced rigidity and precision. The double row configuration provides superior load-carrying capability compared to single row designs, making it an excellent choice for heavy-duty industrial equipment operating in challenging conditions.
Key Features:
- Double row angular contact design for increased load capacity and rigidity
- 30-40 degree contact angle for optimal radial and axial load distribution
- Sheet steel cage for lightweight and cost-effective operation
- Open bearing design (no seal) suitable for clean, dry environments
- Normal radial clearance for standard applications
- Wide operating temperature range: -20°C to +150°C
- Compact dimensions: 45mm bore x 100mm OD x 39.7mm width
- Tolerance class P0/PN2 (ABEC 1) for reliable precision
- Premium NTN manufacturing quality for extended service life
