Single-row open radial needle roller bearing without inner ring NTN RNA4948 with dimensions 265*320*80 mm.
Simple and durable design, precise positioning of rollers in 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.

Calculated dynamic load 550 kN, calculated static load 1350 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.
