DSP / MDSP Series

Overview of DSP- / MDSP- Series Bearings

The DSP- / MDSP- Series Airframe Control Ball Bearings are robust, self-aligning solutions engineered to handle heavy-duty loads in demanding aerospace environments. With a double-row configuration and built-in self-alignment capability, these bearings compensate for shaft misalignment and housing deformation while maintaining smooth rotational performance.

Key Features

Material Excellence: Constructed from high-grade AISI 52100 chrome steel for superior fatigue resistance, hardness, and dimensional stability.
Wide Operating Temperature: Functions reliably in temperatures ranging from -65°F to +250°F (-54°C to +121°C), ideal for aviation use.
Integrated Sealing: Features nonremovable PTFE seals that protect internal components from contaminants, moisture, and debris.
High-Performance Lubrication: Pre-lubricated with MIL-PRF-81322 aerospace-grade grease at a minimum 80% fill, ensuring long service life and reduced maintenance.
Self-Aligning Capability: Designed to correct misalignment in mounting or during operation, reducing stress and improving system reliability.
Corrosion Protection: All external surfaces, except the bore, are cadmium plated per AMS-QQ-P-416, offering corrosion resistance and dimensional accuracy post-plating.

Customization Options

To meet unique aerospace system requirements, the DSP- / MDSP- Series bearings can be tailored with:

Non-standard dimensions or bore sizes
Alternative bearing steels or coatings
Custom radial internal clearances and precision tolerances
Application-specific lubrication solutions
Modified seals or shield configurations

Dimensional Standards

All dimensions are listed in inches unless otherwise noted.
Stated dimensions reflect the final product condition after cadmium plating.

Applications

These self-aligning, heavy-duty bearings are ideal for:

Aircraft control surface hinges
Landing gear assemblies
Structural joint linkages
Rotary-wing and fixed-wing flight control systems

Conclusion

The DSP- / MDSP- Series Airframe Control Ball Bearings are a proven choice for aerospace engineers seeking precision, alignment compensation, and exceptional performance under high loads. Their robust design and customizable features make them suitable for both OEM production and MRO environments.
