Product detailed description
Bearing - NA 4907 DKF
NA 4907 DKF – needle roller bearing with inner ring
The NA 49 series combines a machined outer ring, a needle roller and cage assembly, and a separate inner ring. The hardened raceway on the inner ring simplifies use on shafts whose surface is not suitable as a direct bearing raceway.
Key features
- Type: radial needle roller bearing with machined rings
- Dimensions d×D×B: 35 × 55 × 20 mm
- NA design: supplied with an inner ring; the corresponding RNA series has no inner ring
- Loads: high radial load capacity with a compact cross-section
- Axial forces: must be supported by separate axial guidance or other design elements
- Version: open and requires suitable lubrication
- Manufacturer: DKF
Applications
Suitable for gearboxes, pumps, agricultural machinery, machine tools and other compact mechanisms exposed to high radial loads and restricted space.
Selection and installation
The inner ring can be installed separately, simplifying assembly. Protect the fine needles and raceways during installation, use the specified fits and ensure lubrication across the full bearing width. If the arrangement must carry axial forces, provide a separate locating element.
