Sheaves are used in crown and traveling blocks as well as in heave compensation systems. Reliability under high static and dynamic loads is required

to ensure maximum uptime under the extreme range of drilling conditions.

The solution: The Schaeffler group provides traditional, high capacity, double row taper designs in the commonoilfield sizes meeting API 8C. Banitic

hardened components provide for a soft core with lower retained austenite levels to provide thermal stability under the extreme range of conditions.

A complete range of full complement cylindrical bearings can be specified as well. Seals are available on both cylindrical and tapered roller designs.

These seals are designed specifically for the extreme conditions found in the industry.
