KA050XP0 Bearing Product Overview & Core Advantages
The KA050XP0 is a high-precision thin section bearing designed for applications demanding compact design and high load capacity. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction with a single bearing row. Its inch-series dimensions (5" bore, 5.5" O.D., 0.25" width) and ABEC-1 precision make it an ideal solution for space-constrained, high-reliability systems requiring smooth motion and accurate positioning.
KA050XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA050 | Indicates the specific bearing size series with a 5-inch bore diameter. |
| X | Denotes the Four Point Contact design, enabling high moment load capacity. |
| P0 | Specifies the Open (unsealed) construction and standard ABEC-1 tolerance class. |
KA050XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to support significant combined radial and axial loads as well as high moment loads (Static Load Moment: 4180 lbf), effectively replacing more complex bearing arrangements.
- Thin Section Construction: The compact cross-section (0.25" width) maximizes space efficiency while maintaining high bearing rigidity and load ratings, crucial for precision machinery.
- High-Performance Materials: Manufactured from Chrome Steel rings and balls with a Brass cage for durability, stability, and reliable operation.
- Precision Engineering: Built to ABEC-1 standards with controlled radial internal clearance (0.0000 – 0.0005") for smooth, precise rotation and reduced vibration.
KA050XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuator arms where compact size and high moment load capacity are critical.
- Aerospace & Defense: Gimbals, radar platforms, and control surface mechanisms requiring lightweight, high-precision components.
- Medical Equipment: Imaging scanners (CT/MRI) and surgical robot joints demanding smooth, precise motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where cleanliness and accuracy are paramount.
- Industrial Automation: Rotary tables, indexing heads, and other precision motion control systems.
