Single Row Taper Roller Bearings
Single row tapered roller bearings are the most basic and widely used tapered roller bearings comprising solid inner and outer rings with tapered raceways and tapered rollers with cages. The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction. Tapered roller bearings are designed to accommodate combined loads as well as radial load and axial load in one direction. The axial load capacity is largely determined by the contact angle α, which corresponds to the raceway angle of the cup, the larger the contact angle, the higher the axial load carrying capacity is.
The bearings are separable, thus, the inner ring with rollers and cage assemblies can be mounted separately with the outer ring. They are normally axially adjusted against a second bearing fitted in a mirror image arrangement.
Single Row Tapered Roller Bearings in Metric and Inch Sizes
Tapered roller bearings are available in metric and inch sizes. The series code of metric bearing corresponding to the ISO standards, while the inch bearing have a completely different code system. Both the inner ring with roller and cage assemblies and the outer ring have an independent code. The code of a complete bearing comprises both the inner ring and outer ring codes that are separated with an oblique line.
Single Row Tapered Roller Bearings With Flanged Outer Ring
Certain sizes of single row tapered roller bearings are also available with a flange on the outer ring. Bearings with this external flange can be axially located in the housing to provide a simplified, more compact bearing arrangement. The bearing house is more easy to be manufactured, as no shoulder is required.
Single Row Tapered Roller Bearings Assembled in Pairs
Single-row tapered roller bearings are also available in matched pairs. These are face-to-face and back-to-back arrangements. The matched bearings can support high axial forces in double directions and a certain tilting moment. The clearance of matched bearings are defined by the spacer between two bearings, there is only one outer ring spacer in face-to-face arrangement, while it need both inner ring and outer ring spacers in back-to-back arrangement.
