Rexnord® Shafer® and Rexlon® bearings are used in the main and tail rotor linkages ,and provide long life under extreme load/motion environments. Shafer bearings can be relubricated to prolong bearing life and reduce costly bearing change-out.
Rexlon molded liner bearings provide long life and low wear rates under high vibratory load and small motion conditions.
Helicopter Pitch Links
Helicopter pitch links are designed for flight control applications. They use a variety of configurations, and include the following ideal features:
• Designed for use in oscillatory high-speed motion
• Designed for use in systems requiring low friction and low wear
• Self-lubricated cartridge or integral design for weight and envelop reduction
Helicopter Transmission Mounts and Helicopter Engine Mounts
Mount designs are used to isolate radial motion to a concentrated part of the helicopter. These are often Slotted Entry, greased (or self-lubricated), sealed bearings. Helicopter bearing mounts are usually subjected to high vibration and dithering motion.
PSI® bearings are preferred by OEMs because they offer the following features that make them ideal for bearings requiring high vibration and dithering motion:
• Controlled clearance
• Lubrication flexibility
• Excellent ball-to-race conformity
• High stiffness
• Corrosion resistance
