A rotor system elastomeric bearing is a key component of a rotor system used in helicopters or other rotorcraft, and its basic structural composition is a high load-carrying-capacity multilayer stack of rubber and metal spacers. As a single component, it can realize the rotor arm's movement in three directions: swinging, torsion, and oscillation, which significantly reduces the number of components and structural weight. In addition, compared with the spherical joints on traditional metal hinged rotors, the rotor elastic bearing has no gaps, is naturally resistant to sand and dust erosion, and is characterized by a long service life and easy maintenance.

Rotor system elastomeric bearings are also highly efficient at absorbing and dissipating vibrations and shocks generated by the rotor system, which not only mitigates the vibration levels of the fuselage and rotor blades, but also greatly reduces vibration-related fatigue damage.

Our team has profound experience knowledge and technical strength in the field of rotor system elastic bearings, and has presided over the development of rotor elastic bearings for many domestic helicopters. We have successfully combined advanced material technology, precision molding process, and simulation design technology, and realized the technological breakthrough of rotor elastic bearings, which have many advantages, such as good performance, long service life, and low cost.
