DW-K/DW-

Overview of DW-K / DW- Series Bearings

The DW-K / DW- Series Airframe Control Ball Bearings are engineered to deliver reliable operation under intermediate-duty load conditions. Designed with an extra-wide, double-row configuration, these bearings offer improved load distribution and system rigidity, making them ideal for aerospace control mechanisms and structural joints.

Key Features

• High-Strength Material: Manufactured using premium AISI 52100 chrome steel, offering superior hardness, fatigue resistance, and dimensional stability.
• Broad Temperature Range: Operates effectively within a wide temperature range from -65°F to +250°F (-54°C to +121°C), suitable for harsh aerospace environments.
• Sealing Technology: Equipped with nonremovable PTFE seals that provide excellent protection against contaminants and moisture ingress, extending bearing life.
• Lubrication: Pre-lubricated with MIL-PRF-81322 grease at a minimum fill level of 80%, ensuring consistent low-friction performance.
• Convergent Contact Angles: Designed with convergent contact geometry for optimized thrust and radial load handling, reducing misalignment and enhancing rotational stability.
• Corrosion Protection: All external surfaces (excluding the bore) are cadmium plated in accordance with AMS-QQ-P-416 to prevent corrosion and ensure precise post-plating dimensions.

Custom Engineering Options

To meet specific project requirements, the DW-K / DW- Series can be customized upon request. Available options include:

• Alternative materials and special coatings
• Non-standard bore or outer dimensions
• Customized internal clearances and tolerances
• Application-specific lubrication methods
• Modified seal configurations or integrated features

Dimensional Standards

• All dimensional values are provided in inches unless otherwise noted.
• Specified dimensions reflect final values after cadmium plating is applied.

Application Areas

These bearings are particularly suited for:

• Airframe control linkages
• Flight surface actuation systems
• Landing gear and pivot assemblies
• Rotary wing structural joints

Conclusion

The DW-K / DW- Series offers a reliable, engineered solution for aerospace systems requiring precision, durability, and structural integrity. With robust construction, efficient sealing, and customizable specifications, these bearings are a trusted choice for both OEM and MRO aerospace applications.
