SKF announces a new range of pitch and yaw slewing bearings that have been designed using state-of-art calculation models to maximize turbine performance and bearing life.

The new bearings have special surface treatments to protect against corrosion, and false-brinelling is limited by specially selected grease.

Fitted with an innovative, new, automatic lubrication system that distributes small amounts of grease to all lubrication points for up to 6 months, this reduces maintenance costs and lubricant consumption. After 6 months only the central reservoir needs refilling.

A patented seal solution avoids grease leakage and water ingress, and withstands ring deformations under load as well as internal grease overpressure.

The SKF range of pitch and yaw slewing bearings are available in different designs; single row and double row four point contact ball bearings. They have high load carrying capacity and are preloaded for extra reliability. Pitch bearings can be supplied with or without integrated gearing. Yaw bearings can be supplied with an integrated gear ring, enabling direct drive and eliminating the need of an additional gear ring.
