High radial capacity in compact spaces

Practical benefits

Minimal radial space required: You create ultra-compact bearing arrangements by utilizing the shaft and housing bore as raceways.
High radial load capacity: The pressed sheet steel cage and needle rollers allow you to carry heavy radial loads reliably.
Precise and smooth operation: You achieve high rigidity and precise guidance for demanding mechanical assemblies.

In a nutshell

The right choise for

When designing or maintaining compact machinery, the Skf k 42X50X20 needle roller and cage assembly provides high radial load capacity within minimal radial space. Operating directly between the shaft and housing bore without separate rings, it saves critical room in gearboxes, transmissions, and drivetrains. The robust sheet steel cage guides the rollers with high precision, ensuring excellent stiffness, low friction, and smooth operation under heavy radial loads. Featuring an inner diameter of 42 mm, an outer diameter of 50 mm, and a width of 20 mm, this single-row assembly comes without seals and without pre-lubrication, allowing you to apply the appropriate lubricant during installation for your specific mechanical assembly.
