Koyo Bearings in Qatar

Overview

Koyo is the bearing brand of JTEKT and has been making bearings since 1921. It was the first in Japan to produce four row taper roller bearings for rolling mill work rolls, in 1943, and heavy industry has been its ground ever since: steel making, railways, wind power and aircraft.

Reading a Koyo number

These are the codes on the Koyo bearings we hold.

Code	What it means
7xxx	Angular contact ball bearing, which takes combined radial and axial load in one direction
B	Contact angle variant on an angular contact bearing
C3	Internal clearance greater than normal

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 Koyo 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.
