The single-row tapered roller bearings are 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 or more bearings are matched and used together.
There are the standard, medium and steep types which differ 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 smaller 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.
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.
Features and benefits:
· Forged steel vs. seamless tubing
· Improved fatigue life
· Reduced noise vibration
· Super finished raceways
· Crowned inner ring, raceway & rollers
