INA 40 mm Inside Diameter Drawn Cup Needle Roller Bearing Open End 47 mm Outside Diameter BK4020-A

INA BK4020-A drawn cup needle roller bearing features a 40 mm inside diameter and 47 mm outside diameter, offering a very small radial section height. This bearing type is composed of thin-walled, drawn cup outer rings combined with needle roller and cage assemblies, forming a complete bearing unit designed for compact and easy-to-fit installations with high radial load carrying capacity.

The BK4020-A model has an open end type configuration, ensuring efficient lubrication and relatively straightforward assembly. Its 20 mm race width and parallel bore type provide stable and accurate bearing positioning within machinery.

Constructed with a steel cage, this bearing withstands demanding operating conditions. It has a static load rating of 52 kN and a dynamic load rating of 25.5 kN, supporting substantial mechanical stresses. The limiting speed of 6600 rpm allows this bearing to be used effectively in variable-speed industrial equipment.

Drawn cup needle roller bearings like the BK4020-A are ideal for applications requiring space-saving solutions while maintaining high radial load capacity. They are frequently utilized in automotive, manufacturing machinery, and other mechanical and fluid power systems.

This product does not carry specific approval standards but is built to reliable industrial quality by INA. It serves well in industrial, manufacturing, and construction settings where robust roller bearings are required for rotary motion arrangements.
