Heavy load support by Skf
- High radial load capacity: Compact cylindrical rollers allow you to carry heavy radial loads within extremely confined spaces.
- Integrated double contact seals: Dual rubber seals prevent contamination from entering while keeping essential lubricating grease securely inside.
- Straightforward inner ring mounting: Featuring a machined inner ring, you achieve fast and stable installation directly onto machine shafts.
With the Skf na 4908.2RS single row needle roller bearing, you reliably carry heavy radial loads within restricted spaces. Featuring a solid inner ring, this complete bearing is ideal for industrial gearboxes, powertrains, and pumps where machine shafts are not hardened as direct raceways. Integrated dual-side rubber contact seals prevent dust and moisture from entering while keeping lubricant securely inside, significantly reducing maintenance needs. Sized at 40X62X23 mm and equipped with dedicated lubrication holes in both rings, it ensures fast installation and long-lasting mechanical support.
Product description
Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication. The inner ring contains an additional lubrication hole.
- High radial load carrying capacity
- High stiffness and low cross-sectional height
- Accommodate axial displacement in both directions
- Separable design
- Integral sealing prolongs bearing service life
