Product detailed description
Bearing - NA 4901 DKF
NA 4901 DKF is a radial needle roller bearing with an inner ring and dimensions 12 × 24 × 13 mm. The NA 49 series combines a small radial cross-section with high load capacity through a large number of needle rollers.
Key features
- bore diameter: 12 mm
- outside diameter: 24 mm
- width: 13 mm
- machined outer and inner rings
- high radial load capacity in a compact envelope
- manufacturer / brand: DKF
Typical applications
The bearing is used in gearboxes, clutches, machine mechanisms, power tools and other positions with limited radial space. It is intended primarily for radial loads; axial forces must be supported by other design elements.
Installation and lubrication
Both rings require accurate seats, good alignment and clean lubricant. Do not transmit fitting force through the needles and protect the raceways against indentation. The designation contains no sealing suffix, so verify the lubrication method and external contaminant protection before ordering. Also compare the complete code, dimensions, clearance and operating speed with the original bearing.
