AMB

Overview of AMB Series Aerospace Spherical Bearings

The AMB Series plain spherical bearings are specifically developed for aerospace control and structural joints. These bearings accommodate angular misalignment and oscillating motion in airframe systems, making them ideal for high-reliability flight applications.

Key Features and Specifications

• Inner Race Surface: The spherical inner diameter (ID) of the race is treated with either a nitriding or Malcomizing process. These surface hardening treatments significantly improve wear resistance, surface hardness, and fatigue strength for aerospace-grade endurance.
• Free Rotation: Balls are engineered to rotate freely under light finger pressure at 72°F (22°C), ensuring low-friction performance and easy manual inspection during assembly or maintenance.
• Full Interchangeability: Bearing balls are fully interchangeable without the need for selective assembly. This design enhances maintainability, reduces part inventory complexity, and simplifies field replacement.
• Temperature Range: Operating reliably across a broad temperature range of -65°F to +350°F (-54°C to +177°C), the AMB Series performs consistently in both high-altitude cold starts and high-heat environments.

Technical Benefits for Aerospace Applications

• Accommodates angular misalignment under load
• Supports oscillating, tilting, and limited rotary motion
• Long-term corrosion and wear resistance
• Minimized installation variability due to interchangeable components

Customization and Engineering Support

For specialized aerospace systems or unique structural configurations, customizations are available upon request. These include material selection, race treatments, dimensional tolerances, and surface coatings tailored to mission-specific requirements.

Applications

The AMB Series spherical bearings are ideal for:

• Aerospace control linkages
• Structural pivot joints
• Landing gear and flap mechanisms
• Rotor systems and airframe articulation points
