Product Description

KOYO taper roller bearing 32306JR 30*72*27mm

Tapered roller bearings are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.
Along with metric series bearings, inch series bearings are also available.
This type of bearing is suitable for applications that involve heavy or impact loading.
  • Single-row tapered roller bearings

Able to carry radial and axial load in one direction simultaneously.

Because an axial component of force is produced when this type of bearing is loaded radially, two bearings are used together facing one another, or two or more bearings are matched and used.

There are the standard, medium and steep type which are different in contact angle size. Medium-tapered metric series bearings are identified by the supplementary code "C" which is added as a suffix to bearing numbers.

Bearings whose cup width, cup small inside diameter and contact angle are determined in accordance with ISO 355 specifications are identified by the supplementary code "J" as a suffix.

Cone assemblies and the cups of such bearings are inter-changeable with those of bearings produced abroad if the bearing numbers are the same.
  • Application
Motorcycle rear axle wheel hub, heavy machine tools' main shafts, big power reduction gears, axletree axle boxes, roller wheels of transportation devices, and the supporting rollers and working rollers of the rolling mills.
