B500DD / MB500DD

Overview of B500DD / MB500DD Series

The B500DD / MB500DD Series Airframe Control Ball Bearings are engineered for applications that require minimal weight and consistent anti-friction performance in limited-space environments. Designed for aerospace systems, these bearings are particularly suited to control mechanisms and instrumentation requiring reliable rotation at high speeds with low radial loads.

Key Features

• Extra Light Duty Design: Ideal for space-sensitive installations with minimal load requirements.
• Anti-Friction Performance: Precision manufacturing ensures smooth, consistent operation with low torque resistance.
• Durable Construction: Rings and balls are made from high-grade AISI 52100 chrome steel for enhanced fatigue and wear resistance.
• Sealed for Protection: Nonremovable PTFE seals provide long-term defense against contaminants and moisture without requiring maintenance.
• High-Temperature Operation: Suitable for environments ranging from -65 °F to +250 °F (-54 °C to +121 °C), ensuring performance in demanding aerospace conditions.
• Military-Grade Lubrication: Pre-lubricated with MIL-PRF-81322 grease at a minimum 80% fill, ensuring reliable lubrication over the product’s lifetime.
• Corrosion-Resistant Finish: External surfaces are cadmium plated per AMS-QQ-P-416 (except the bore), with dimensions maintained after plating.
• Dimensional Interchangeability: Fully interchangeable with the B500/MB500 series in bore size, outside diameter, and width, simplifying design upgrades and replacements.

Typical Applications

These extra light duty ball bearings are ideal for:

• Aircraft control surfaces and actuators
• Flight deck mechanisms and control linkages
• Instrumentation and lightweight robotics
• Precision rotating assemblies with low radial loads

Customization Options

To meet unique design requirements, the following customization options are available upon request:

• Alternative materials such as stainless steel or hybrid ceramic
• Special tolerances and radial internal clearances
• Custom lubrication for extreme or specialized environments
• Alternative surface treatments beyond cadmium plating
