Single row open radial needle roller bearing without inner ring NTN RNA4903R with dimensions 22*30*13 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. Designed to withstand one-sided radial load.

Designed dynamic load 11.2 kN, calculated static load 14.6 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. Can be used with an inner ring, which is sold separately.
