AT A GLANCE
Actuators are responsible for controlling landing gear, rudders, elevators, flaps, spoilers, and cargo doors in aircrafts. The seamless operation of these systems is essential to assuring aircraft have a safe flight from takeoff to landing.
Actuators must perform with no stick slip and with consistent friction under all conditions. Due to this, they require high performance, reliable bearings that can withstand harsh operating conditions.
GGB DU® self-lubricating bearings consist of a steel backing with a porous bronze inner structure that is coated with an antifriction polymer resin lining. This composite bearing structure can withstand static loads up to 250 MPa and temperatures up to 280oC.
With a thin wall design, DU® plain bearings assist in achieving weight and space savings without compromising on strength.
DP4® metal-polymer low friction bearings offer similar properties to DU® with the added benefit of being lead-free. (DP4® is compliant with RoHS – Restriction of Hazardous Substances and WEEE – Waste Electrical and Electronic Equipment directives).
The following properties of DU® make it an excellent choice for actuator applications:
