The INA NKXR20 is a combined needle roller and axial cylindrical roller bearing to DIN 5429. A caged needle roller set takes the radial load and an axial cylindrical roller component takes thrust in one direction, in a single unit. Unit Quantity: 1 Pc. Single combination bearing, straight bore, open, without end cap, for oil lubrication.
NK — machined needle roller bearing element, rollers running directly on the shaft.
X — axial bearing component combined with the radial needle roller assembly, acting in one direction.
R — the axial component uses cylindrical rollers (NKX uses balls).
20 — bore diameter in millimetres.
XL — Schaeffler’s current-generation designation; NKXR20-XL supersedes NKXR20.
