The many bearings in a motorcycle have various functions such as supporting a spinning crankshaft or keeping the wheels on the road.

They guide and support moving parts, reduce emitted heat, alleviate friction and minimize power loss. Koyo is a manufacturer of motorcycle bearings for several well-known motorcycle brands like Kawasaki and Suzuki. We offer a range of bearings for a variety of applications including chassis, engine and motorcycle transmission.

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.
