Description

A rod end self-lubricating spherical plain bearing integrates a bearing with a threaded rod end. Its self-lubricating core makes it ideal for aviation applications characterized by difficult maintenance, high loads, and low-speed oscillation.

Materials: Rod end bodies are forged from specific alloy steels or titanium alloys. Key surface roughness is controlled to Ra ≤ 0.8 μm.

Mechanical Performance

 Radial ultimate static load: ≥120% of the design value.

 Axial push-out force: Withstands ≥1.5 times the rated load without separation.

 Fatigue life: Endures a minimum of 50,000 cycles under alternating loads.


Quality Inspection
Tests include static load, fatigue life, and environmental checks. Radial clearance is measured with specialized tooling.

Applications

Rod end self-lubricating spherical plain bearing primarily used in aircraft control systems, landing gear, helicopter rotor assemblies (control linkages, swashplates), and flap transmission mechanisms.

These bearings are indispensable in modern aviation. Their maintenance-free operation, high reliability, long life, and tolerance for extreme environments perfectly align with the industry's demands for safety, reliability, and economy. They are critical components from flight controls and landing gear to engines, ensuring safe and smooth operation.
