Matched tapered roller bearings arranged face-to-face (X-arrangement, load lines diverge towards the bearing axis) accommodate high radial loads and axial loads in both directions.

The precision manufactured intermediate ring between the outer rings enables 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.

• High radial load carrying capacity
• Designed for axial loads in both directions
• Relatively high stiffness
• Surface finish on the contact surfaces of the rollers and raceways that enhances operational reliability
