Railway Vehicle Gear Reducer KOYO 14125A/14276 Tapered Roller Bearing

Structure:

This type of bearing is equipped with a round platform roller, the roller by the inner ring of the large rim.
Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load.
According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is.
Outer ring and inner assembly (inner ring and roller and cage assembly) can be separated for easy assembly and disassembly.

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.
