Laminated Elastomeric Bearings

Laminated elastomeric bearings are needed in rotor systems (both main rotor and tail rotor) as described in the fully articulated section. These devices are used to transmit loads and motion to the blades of the helicopter given inputs from the fixed controls. In general these products provide a high stiffness in one or combined directions to take loads, while providing a lower stiffness in other directions allowing for motion. Examples of each are shown herewith.

Typical solutions

SKF manufactures all types of laminated elastomeric bearings to accommodate load and motion needs for various main rotor designs. Two typical solutions for main rotors are spherical or thrust shear laminated elastomeric bearings.
