New Dynamic Load Ratings--> Bearing Life Increase 2X

JTEKT Corporation, the Koyo bearing manufacturer, is recognised as the world's largest bearing supplier to the Automotive OE and Components and has been taking major further steps to increase its presence into the Industrial OE and the Aftermarket business by making technological improvements on the standard radial bearing range.

Today we are proud to announce that Koyo will introduce a new Dynamic load rating (1.25 x C). Since the mid 90's Koyo has been testing manufacturing improvements leading to a clearer comparison between actual and calculated bearing life. These achievements reached thanks to improved daily manufacturing processes and also new steel specifications,allow JTEKT to offer today on the market, the longest service life (2X calculated life).

We have officialised this major breakthrough by releasing a promotion campaign supported by a brand new edition of the Koyo General Catalogue 2001-B. Please download it here!.

Our engineers will be pleased to explain in detail the technical reasons behind these improvements and the advantages, that as a user of bearings,you can expect for your operations improvements.

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.
