GDW-K/GDW-

Introduction to GDW-K / GDW- Series Airframe Bearings

The GDW-K / GDW- Series are extra-wide, double-row, intermediate-duty airframe control ball bearings engineered to deliver superior load handling and durability in demanding aerospace systems. Their robust design includes convergent contact angles and a relubrication feature, offering extended operational reliability in mission-critical environments.

Key Features

• High-Grade Steel: Rings and balls are made from premium AISI 52100 chrome steel for excellent wear resistance, high fatigue strength, and reliable long-term performance.
• Temperature Resilience: Operating temperature ranges from -65 °F to +250 °F (-54 °C to +121 °C), suitable for extreme aerospace conditions.
• Sealed for Protection: Equipped with nonremovable PTFE seals that provide effective protection against contaminants while maintaining lubrication integrity.
• Advanced Lubrication: Pre-lubricated with MIL-PRF-81322 specification grease at a minimum fill of 80%, unless otherwise specified.
• Convergent Contact Angles: Precision angular contact design enhances thrust and radial load capacity while improving alignment stability.
• Relubrication Groove: Integrated grease groove and lubrication holes allow for efficient in-service relubrication, extending bearing life in harsh environments.
• Corrosion Resistance: External surfaces (excluding bore) are cadmium plated in accordance with AMS-QQ-P-416, ensuring high resistance to corrosion and dimensional accuracy post-plating.

Application Advantages

The GDW-K / GDW- Series bearings are optimized for:

• Flight control systems
• Landing gear actuation mechanisms
• Helicopter rotor systems
• Robust control linkages and aerospace structural joints

Customization Options

To meet specific performance needs, customers can request custom configurations including:

• Alternative materials and coatings
• Custom radial internal clearances
• Non-standard tolerances
• Application-specific lubrication strategies
• Modified bore or external geometries

Technical Specifications

• All dimensions are expressed in inches unless otherwise specified.
• All dimensions are applicable after cadmium plating is applied.
• Lubrication groove with grease holes enhances field-serviceable performance.

Conclusion

The GDW-K / GDW- Series represents a reliable solution for aerospace and precision control applications where durability, relubrication capability, and high load-handling are essential. For tailored solutions or technical assistance, please contact our engineering support team.
