Tapered Roller Bearing - Metric

  • 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.
