Tapered Roller Bearing - Metric

All About Tapered Roller Bearing

Tapered roller bearings are designed so the inner/outer ring raceway and apex of the tapered rollers intersect at one point on the bearing centerline.
By receiving a combined load from the inner and outer ring, the rollers are pushed against the inner ring rib and are guided by the rib.
Induced force is produced in the axial direction when a radial load is applied, so it must be handled with a pair of bearings.
The inner ring with rollers and outer ring come apart, thus facilitating mounting with clearance or preload.
Assembled clearance is however hard to manage and requires special attention.
Tapered roller bearings are capable of supporting large loads in both the axial and radial directions.
NTN also has a line of case hardened steel bearings designed for longer life.
NTN tapered roller bearings also include bearings with two and four rows of tapered rollers for extra-heavy loads.
