Single row open radial needle roller bearing with inner ring NTN NK45/20R+1R40X45X20 dimensions 40*55*20 mm.
Simple and durable split design, precise positioning of rollers in pressed steel cage windows. The machined outer ring has two guide flanges, an annular groove and lubrication holes. The beadless inner ring provides a split design. Designed to withstand one-sided radial load.

Designed dynamic load 28 kN, calculated static load 52.5 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 by the width of the inner ring raceway.
