Overview
IKO is the brand of Nippon Thompson, and its speciality is the bearing that has to fit where there is no room. A needle roller carries a heavy radial load in a fraction of the section height of a ball bearing, which is why IKO numbers turn up in machine tools, robots and packaging machinery.
Petrofab holds IKO cam followers and thrust bearings in Doha and quotes the rest of the IKO catalogue through its supplier base.
What we supply
Needle roller bearings, cam followers and roller followers, thrust bearings, and linear motion guides, in metric and imperial sizes.

Reading an IKO number
IKO's numbers name the family first. These are the families we hold.
| Code | What it means |
| NART | Roller follower, the miniature series carrying a synthetic resin thrust washer that takes the axial load caused by installation error |
| UU | Seals on both sides |
| R | Cylindrical outer ring surface, as opposed to a crowned one |
| AZ | Thrust bearing: the caged cylindrical rollers of the AZK series combined with a WS inner ring and a GS outer ring |
A bearing usually has an equivalent under another brand, and the letters are where the two differ. Send whichever number is in front of you and we will identify what fits.
Ordering
Send us the IKO number with the quantity. If the marking has worn off, send the bore, the outside diameter and the width, and tell us what it runs in and how hard it works. We will identify the equivalent and quote it. Quantities and delivery are confirmed on the quotation.
