AGB

Key Specifications of AGB Series Aerospace Spherical Bearings

1. Radial Clearance

The AGB Series Aerospace Spherical Bearings feature a precision radial clearance that is free-turning up to a maximum of 0.001 inches. This ultra-low clearance supports high-accuracy movement while maintaining load stability in applications where precise angular motion is essential.

2. Axial Clearance

Axial clearance is also designed to be minimal, with free-turning motion up to 0.005 inches. This helps reduce vibration and axial drift in high-speed or dynamic systems commonly found in aerospace control mechanisms.

3. Concentricity Control

The bearings maintain concentricity within 0.005 inches Full Indicator Movement (FIM) between the outer diameter (D), pitch diameter (E), and bore diameter (B). Such tight concentricity tolerances ensure uniform load distribution, improved bearing performance, and long-term system reliability.

4. Lubrication Standard

Each bearing is prepacked with MIL-PRF-81322 grease, a military-grade lubricant known for its superior thermal stability, water resistance, and anti-wear properties. This lubrication supports extended maintenance intervals and consistent performance under varying operational conditions.

5. High-Temperature Capability

The AGB bearings operate efficiently across a wide temperature range from -65°F to 350°F (-54°C to 177°C), making them suitable for both low-temperature altitudes and high-temperature zones near aircraft engines or hydraulic systems.

6. Lubrication Groove and Grease Flow Design

The lubrication grooves on the inner diameter of the race and the grease holes through the race are precisely machined before the bearing assembly process. Importantly, the swaging operation used to secure the ball does not obstruct grease flow, ensuring reliable lubrication delivery during the entire service life of the bearing.

Application Suitability

The AGB Series is specifically designed for aerospace applications requiring compact design, thermal resilience, and long-lasting mechanical precision. Typical uses include aircraft control systems, linkage joints, and actuators where high-frequency movement and minimal backlash are critical.
