Product summary
AXK 0821 TN: needle roller thrust bearing, brand SKF. Bore diameter d 8 mm, outside diameter D 21 mm, width B 2.75 mm. Dynamic load rating C 7.2 kN, static load rating C0 20 kN, limiting speed 11 000 rpm, weight 0.002 kg.
Needle rollers in a cage between flat washers: axial load capacity with a section height of just a few millimetres.
Where it is used
Gearboxes and transfer cases, steering columns, axial piston pumps and hydraulic motors, compressors, planet gear faces in planetary gear sets. Used where an axial support has to fit into a few millimetres of height.
When not to use
It takes no radial load at all. The needle and cage assembly runs only on ground washers or on faces with a hardness of about 58–64 HRC: on an unhardened face the raceway gets dented. In a high-speed assembly it does not replace a thrust ball bearing.
