Single row tapered bearings support radial and axial loads or pure thrust loads. Because the inner and outer races are separable, they are typically mounted in pairs in opposing directions to keep the bearings from falling apart. Any misalignment increases bearing noise and reduces bearing service life. Pre-configured matched tapered roller bearings are also available to simplify the design and installation process for many applications.
Back to back matched tapered roller bearing
Description
Supports large radial and axial loads in both directions
Operating temperature up to 250°F
52100 alloy steel components
Stamped steel cage
Meets ISO 355 standards
RBEC-1
Open bearing, no seals or shields
Matched back-to-back tapered roller bearings are the most popular double row tapered bearing design. They carry heavy radial and axial loads and axial forces in both directions. They are manufactured together as a set that includes two tapered roller bearings, and a precision machined set of shims. An essential feature of this configuration is that when the shaft thermally expands lengthwise, the axial preload forces decrease in the bearing. It will run at a lower temperature than a face-to-face bearing in the same situation. It is much easier to use in industrial settings where operating temperatures vary significantly.

Matched face to face tapered roller bearings handle axial force in both directions and large radial loads while maintaining accurate centering. They are manufactured together as a set that includes two tapered roller bearings, and a precision machined set of shims. This configuration is more complicated to use correctly and is less popular than the back to back arrangement. Its main advantage is that the axial clearance in the bearing will decrease as it heats. It is more prone to overheating without control of heat flow. Still, it is an excellent choice in equipment that requires tight positioning control, such as machining tools with forced cooling systems.
