Single row open radial needle roller bearing without inner ring NTN NK12/16 with dimensions 12*19*16 mm.
Simple and robust design, precise positioning of rollers in pressed steel cage windows. The machined outer ring has two guide flanges. 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 6 kN, calculated static load 7.7 kN. Normal axial clearance.
The needle roller bearing of this design can withstand significant axial loads and rotational speeds. The axial displacement of the shaft is limited only by the width of the raceway on the shaft.
