KA055XP0 Bearing Product Overview & Core Advantages
The KA055XP0 is a high-precision thin section bearing designed for applications demanding compact design and high load capacity within minimal cross-sections. As a Four Point Contact ball bearing, it excels at supporting combined loads, simultaneously handling significant radial forces and axial loads from both directions. Its ABEC-1 precision grade and optimized internal geometry ensure smooth operation and high reliability in precision equipment and space-constrained assemblies.
KA055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA | Indicates the Reali-Slim series of thin section bearings. |
| 055 | Specifies the cross-section size and bore diameter of 5.5 inches. |
| X | Denotes the Four Point Contact design, enabling combined load capacity. |
| P | Signifies Open construction (no seals or shields). |
| 0 | Indicates a standard radial internal clearance. |
KA055XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row of balls to support substantial radial, axial, and moment loads simultaneously, replacing the need for more complex bearing arrangements and saving critical space and weight.
- High Load Capacity: Engineered for a high static load moment of 5020 lbf-in and a dynamic load moment of 1959 lbf-in, making it suitable for applications with significant overturning forces.
- Precision Performance: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000" – 0.0005"), ensuring smooth, low-vibration, and accurate rotational motion.
- Durable Construction: Features rings and balls made from high-carbon Chrome Steel for wear resistance and a Brass cage for stability and reliable operation at moderate speeds.
- Pre-lubricated: Comes lubricated from the factory for immediate installation and initial operation.
KA055XP0 Bearing Typical Application Areas
- Robotics: Ideal for robot joints and actuators where compact size, low weight, and high moment load capacity are critical.
- Aerospace & Defense: Used in gimbal systems, control mechanisms, and radar platforms that require high precision and reliability in thin sections.
- Medical Equipment: Suitable for CT scanners, surgical robots, and other medical devices demanding smooth, precise motion in a compact envelope.
- Semiconductor Manufacturing: Applied in wafer handling robots and precision stages where cleanliness (open design) and accuracy are paramount.
- Optical and Instrumentation Systems: Used in rotary tables and positioning systems that require minimal friction and high rotational accuracy.
