Family specifications and selection conditions
| Product description | Matched tapered roller bearings arranged back-to-back (O-arrangement, load lines diverge towards the bearing axis) accommodate high radial loads, axial loads in both directions, and tilting moments. The precision manufactured intermediate rings between the innner and outer rings enable a defined internal clearance or preload to be achieved when mounted. Matched tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills, and machines in the mining industry. |
|---|---|
| Manufacturer features | High radial load carrying capacity • Designed for axial loads in both directions • Accommodate tilting moments • Relatively high stiffness • Surface finish on the contact surfaces of the rollers and raceways that enhances operational reliability |
