Construction industry lies at the base of the world economy.

Construction industry lies at the base of the world economy. 

Be it residential, commercial, heavy, civil or industrial edifice, they all require reliable heavy duty machinery and long term, trouble free functioning. JTEKT supplies both standard and customized Koyo products to serve those demanding applications. 

The construction industry may be showing a differential growth pattern all over the world, nonetheless the use of modern technologies is always a must in order to assure reliability and efficiency.

Construction machinery designed for high performance in extreme harsh environments calls for bearings which can withstand these working conditions and at the same time guarantee proper functioning over a long time span. At JTEKT we follow the latest developments in the construction industry closely and our bearings are designed in order to meet up with the demands of this industry.

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.
