Features:
Tapered roller bearings use conical rollers that run on conical races. Most roller bearings only take radial or axial loads, but tapered roller bearings support both radial and axial loads, and generally can carry higher loads than ball bearings due to greater contact area. Tapered roller bearings are used, for example, as the wheel bearings of most wheeled land vehicles. The downsides to this bearing is that due to manufacturing complexities, tapered roller bearings are usually more expensive than ball bearings; and additionally under heavy loads the tapered roller is like a wedge and bearing loads tend to try to eject the roller; the force from the collar which keeps the roller in the bearing adds to bearing friction compared to ball bearings.
Tapered roller bearings are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and pre-loaded mounting can be made.
Tapered roller bearings have metric and inch types different:
