Tapered roller bearings are a unique subset of axial roller bearings in which the rollers are tapered rather than straight right cylindrical. The roller shape allows thrust loads to be withstood in addition to the radial loads. A familiar application for tapered roller bearings is the central hub bearings for automobile wheels. When an auto traverses a turn, the wheels must withstand a significant lateral force, so that tapered roller bearings are necessary. This kind of bearing shell side may limit the axis or axial displacement, does not allow a tilt axis relative to shell hole. In the radial loads, will produce additional axial forces, therefore, generally supported in two bearings, the bearing outer ring and inner ring with the face should be relatively installation.
The main application of such bearings: Automotive front, rear, transmission, differential, pinion shaft, spindle, construction machinery, large-scale agricultural machinery, railway vehicles, gear reduction rolling mill roll neck small deceleration devices.
Structure:
Single row tapered roller bearings - Metric and Inch
Double row tapered roller bearings - Metric and Inch
Single row tapered roller bearings
Such bearings can only limit the shell axis or axial displacement in one direction, a direction under axial load. Under the action of the radial load, axial force generated by the bearing must be balanced. Face to face or back to back two bearings should be used.
Double row tapered roller bearings
Such tapered bearings, while the radial load can withstand two-way axial load. In the bearing axial clearance or shell within the limits of the bi-axial shaft movement.
