Metric and Inch Tapered Roller Bearings

Tapered roller bearings, the outer ring has a tapered raceway, raceway with tapered roller between. If an extension of conical surface, and ultimately converge on the bearing axis point. Tapered roller bearings are mainly used to bear radial load mainly consisting of radial and axial load. The axial load bearing capacity of the decision by the contact angle, the greater the reach, the greater the axial load capacity. Tapered roller bearings for the separation of bearings, roller and cage with the inner ring in the inner components separately with the outer ring installation. 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 purpose 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.

Competitive Advantage
High-precision roller - guide on the featuress to ensure that the pure rolling
Optimal rib design - concentric and maintain accurate positioning
Increased exposure to taper - more axial load.
