Koyo & Koyo-Torrington Needle Roller Bearings brand integration

Following the acquisition of the Needle Roller Bearing Division in 2010, JTEKT has announced full brand integration starting on 1 January 2013. Needle Roller Bearings, branded Koyo-Torrington until the end of 2012, will now bear the Koyo logo exclusively, thus adding to the very complete range of Koyo ball and roller bearings.

 

The decision is justified by the advances in the integration of the ball, roller and needle bearing businesses under the umbrella of JTEKT. Therefore, starting on 1 January 2013, for all your bearing needs, there is only one name you need to know: Koyo.

FAQ

What is a tapered roller bearing?

A tapered roller bearing is a bearing in which tapered rollers (truncated conical rollers) are inserted between the cup (outer ring) and cone (inner ring). The rollers are guided by the cone back face rib.

They have high radial and axial (thrust) load capacities at low to intermediate speeds. Taper roller bearings are available in single-row, two-row and four-row designs. With single-row bearings, the thrust load capacity is about 60% of the radial capacity. Double-row bearings have a greater radial load capacity and can handle thrust loads from both directions. The rollers can be configured so that the contact lines to the races converge or diverge towards the axis of rotation. Diverging double-row bearings increase the rigidity of the shaft mounting, but converging bearings do not. Other configurations for double-row bearings feature a single outer ring and two inner rings, or two outer rings and a single inner ring. Four-row tapered roller bearings consist of four rows of alternating converging and diverging rollers.
