Koyo 33213jr Bearing Steel Single-Row Tapered Roller Bearings

New Competitive High Quality Low Noise Koyo 33213JR Single-Row Tapered Roller Bearings

Tapered roller bearings consist of four interdependent components:
The cone, or inner ring; The cup, or outer ring; The tapered rollers, or rolling elements; And the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.

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.

Double-row tapered roller bearings
These bearings are divided into the TDO type which has one double cup and two single-row cones, and the TDI type which has two single-row cups and one double cone.

Both accommodate radial and axial loading in both directions.
These two also carry moment loads, however, the TDO type is superior to the TDI type, because the distance between load centers is longer in the TDO type.
The spacer of the TDO type, or the TDI type, pre-adjusts the internal clearance to provide proper operating clearance after mounting.
