KSP / MKSP Series

Overview of KSP-, KSP-A / MKSP-, MKSP-A Series Bearings

The KSP-, KSP-A and MKSP-, MKSP-A series are part of a specialized line of self-aligning, single-row airframe control ball bearings. These bearings are designed to handle both light-duty and heavy-duty requirements while compensating for misalignment in control linkages and mechanical assemblies. Their self-aligning capabilities make them ideal for dynamic environments where structural deformation or vibration is present.

Key Features

Material: Constructed with high-grade AISI 52100 chrome steel for excellent wear resistance and fatigue life.
Design: Self-aligning single-row design for improved angular misalignment accommodation and precision.
Duty Ratings: Available in light-duty (KSP-, KSP-A) and heavy-duty (MKSP-, MKSP-A) configurations to meet various aerospace system requirements.
Sealing: Nonremovable PTFE seals offer reliable protection against dust, debris, and moisture without requiring frequent maintenance.
Temperature Range: Suitable for operation between -65 °F and +250 °F (-54 °C to +121 °C), accommodating a broad range of aerospace environmental conditions.
Lubrication: Pre-filled with MIL-PRF-81322 synthetic grease to ensure long-lasting performance and corrosion resistance; 80% fill standard.
Surface Finish: External surfaces (except bore) are cadmium plated according to AMS-QQ-P-416 for enhanced corrosion protection. Dimensional specs apply after plating.

Applications

These bearings are commonly used in:

Aircraft flight control linkages
Flap and rudder actuation systems
Missile fin control mechanisms
Rotating joints and assemblies subject to angular misalignment
