SSW-AK

Overview of SSW-AK Series Airframe Control Bearings

The SSW-AK Series is a specialized subset of our Airframe Control Ball Bearings product line, designed for high-precision control mechanisms in aerospace systems. With a flanged outer ring for secure axial retention, these bearings offer excellent corrosion resistance and long-term operational reliability in moisture-prone environments such as coastal regions, naval aircraft, and high-altitude control systems.

Key Design Features

• Material: Constructed from high-quality AISI 440C stainless steel, offering excellent hardness and superior corrosion resistance compared to standard bearing steel.
• Structure: Intermediate-duty, single-row design with flanged outer rings for simplified mounting and improved axial load distribution.
• Sealing: Equipped with nonremovable PTFE (polytetrafluoroethylene) seals that provide protection against contaminants and reduce maintenance requirements.
• Temperature Range: Rated for operational temperatures from -65°F to +250°F (-54°C to +121°C), suitable for extreme aerospace environments.
• Lubrication: Factory-lubricated with MIL-PRF-81322 aerospace grease at 80% fill, ensuring high performance under load and resistance to moisture and oxidation.
• Corrosion Protection: Fully stainless construction with cadmium-free surfaces, meeting RoHS and environmental compliance requirements.
• Precision: Aerospace-grade dimensional tolerances and surface finishes to ensure consistent performance in flight-critical systems.

Common Applications

The SSW-AK Series bearings are commonly deployed in aerospace systems where high humidity, salt spray, or corrosive conditions are a concern. Typical use cases include:

• Rudder and elevator control systems
• Flap and slat actuators
• Push-pull linkage assemblies
• Naval aircraft exposed to marine environments

Customization and Availability

We offer a variety of customization options to meet your engineering specifications, including:

• Alternative stainless steel grades or hybrid materials
• Special radial internal clearances and tolerance classes
• Alternate lubricants for extreme temperature or vacuum applications
• Plating options (e.g., dry film lubricants, passivation)

All standard dimensions are provided in inches unless otherwise specified. Custom solutions are available upon request.

Technical Compliance

• Lubrication: Compliant with MIL-PRF-81322 specification for high-performance aerospace grease.
• Environmental: Cadmium-free design adheres to AMS and RoHS environmental standards.
