Description
This combined needle roller bearing carries both radial and axial loads in a single unit, using an axial ball bearing component to support single-direction axial forces, built to DIN 5429. Bore diameter is 12.0 mm, outside diameter 21.0 mm, height 23.0 mm, net mass 42.73 g, with a limiting speed of 11000.0 1/min. The design includes an end cap and a standard cage. Sealing on one side (Z) protects the needle roller set from contamination while allowing grease lubrication, which suits applications where combined radial and single-direction axial loads occur within a compact envelope. The standard cage guides the needle rollers for reliable operation at the rated limiting speed, and the axial ball bearing component handles the axial load path without requiring a separate thrust bearing.
