IKO NATA5913 Needle Roller and Angular Contact Ball Bearing, 65 x 90 x 34 mm
Out of stock
IKO NATA59 combined needle roller bearings pair a caged needle roller bearing with an angular contact ball bearing. The needle rollers carry radial load and the ball bearing carries axial load in one direction, in a compact unit. This page lists 12 sizes: 15 to 65 mm bore, 28 to 90 mm outside diameter.
Combined type bearings are compact and economical, can take radial and axial loads at the same time, and are widely used in machine tools, textile machinery and industrial machinery. The bearing has an inner ring.
For axial load in both directions, mount two NATA bearings symmetrically, or use the NATB type with a three-point contact ball bearing, which takes two-direction axial load in one unit.
Where this product is used
- Machine tools and industrial machinery
- Shafts that see radial load and axial load in one direction at the same time

C and C0 are the basic dynamic and static load ratings in the radial and axial directions. Width C is given for both types, and B (inner ring width) for NATB.
Selecting the right option
Choose the size with the Inside Diameter (mm) option, which is the bore of the bearing.
NATA takes axial load in one direction. Choose NATB for axial load in both directions in one unit.
Fitting and use
These bearings are not prepacked with grease, so lubricate them before use. The outer ring has an oil groove and an oil hole. The allowable rotational speed in the tables is for oil lubrication; for grease lubrication use up to 60% of it.
Use a shaft tolerance of k5 and a housing bore tolerance of M6. Axial load should not exceed 25% of the radial load. For axial load in both directions, mount two NATA bearings symmetrically with an axial clearance of 0.2 to 0.3 mm.
