Single-row open radial needle roller bearing without an inner ring NTN NK25/20RU15 dimensions 25*33*20 mm.
Simple and robust design, precise positioning of rollers in the pressed steel cage windows. The machined outer ring has two guide flanges, an annular groove and lubrication holes. There is no inner ring; the raceway is a hardened and ground shaft of the appropriate diameter. Designed to withstand one-sided radial load.

Designed dynamic load 19 kN, calculated static load 30 kN. Normal axial clearance.
The needle roller bearing of this design can withstand significant axial loads and rotation speeds. The axial displacement of the shaft is limited only by the width of the raceway on the shaft.
