LEONESSA Bearing (Yancheng) Co.,Ltd was founded in 2011 with La Leonessa S.p.A as the majority shareholder. La Leonessa is specialized in manufacturing slewing bearings for 50 years with great reputation in the industry. We are committed to providing tailored high quality products and services to our customers.

Slewing bearings, also called “joint of machine” and widely used in industry. It is an important transmission component for the machine that needs to make relative rotary motion between two objects which bear axial force, radial force and tilting moment at the same time. With the rapid development of machinery industry, slewing support has been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

Wind turbine bearings mainly have four types: four contact ball bearings, cross roller bearings, cylindrical roller bearings and so on. The yaw bearing is installed at the connecting part of the tower and the cockpit, and the variable propeller bearing is installed at the connecting part between the root of each blade and the hub.

When the direction of the wind changed, the pod of the wind generator must also be rotated accordingly. For this purpose, the yaw bearing is used between the pod and the tower. In order to achieve optimal generator power output at different wind speeds, the turbine blade Angle must also be variable. To this end, the blade and the main engine must be connected by variable paddle bearings.

LEONESSA Yancheng provides packaging technology solutions for yaw and variable propeller slewing bearings in wind power industry for domestic and foreign customers. We specializes in the field of medium and minimum wind power turbine slewing bearing. We provide products with high quality, excellent performance and long service life and global after-sales service to customers.
