Single-row tapered roller bearing

A single-row tapered bearing is usually adequate for the most straightforward applications (e.g., angular forces on a fixed point and with only mild fluctuation). To find the right one, you'll need to determine whether the end-use of the tapered bearing will have more radial or axial loads. There are axial-only tapered roller bearings called thrust tapered bearings that resemble flat rings or disks where the rollers are perpendicular to the bearing bore axis. When multiple bearings are required, it could be advantageous to use two- or more single-row tapered bearings rather than multi-row bearings within a single housing. One such example is if one bearing will need to be maintained, adjusted, or replaced separately from the other. Another is when there is a need to allow for flexibility in design and add or subtract individual single-row tapered bearings, which is impossible with a multi-row tapered bearing.
