KA047XP0K Bearing Product Overview & Core Advantages
The KA047XP0K is a high-performance thin section bearing designed for applications requiring maximum load capacity in minimal space. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction with exceptional rigidity. Its ultra-thin cross-section (0.25" width) and inch-series sizing make it ideal for compact, weight-sensitive designs in robotics, aerospace, and precision instrumentation. Manufactured to ABEC-1 precision standards with brass cage construction, this bearing delivers reliable performance and long service life.

|---|---|---|
| KA047 | Bore diameter designation (4.75") | Standard inch sizing for compatibility |
| XP | Extra Precision designation | Enhanced running accuracy and consistency |
| 0K | Open construction, lubricated | Allows custom lubrication schemes |
KA047XP0K Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support combined radial and axial loads in any combination, making it exceptionally versatile for complex loading conditions.
Thin Section Construction: With a consistent 0.25" cross-section regardless of bore size, this Reali-Slim bearing provides maximum load capacity in minimal space, enabling compact and lightweight machine designs.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (±0.0010" bore tolerance) ensures smooth operation and precise positioning accuracy.
High-Capacity Brass Cage: The brass cage provides excellent strength and wear resistance, maintaining ball alignment and distribution under high dynamic loads (834 lbf radial, 1350 lbf axial).
Chrome Steel Construction: Both rings and balls are manufactured from high-grade chrome steel, offering superior hardness, wear resistance, and fatigue life for demanding applications.
KA047XP0K Bearing Typical Application Areas
- Robotics: Joint actuators, rotary unions, and positioning mechanisms requiring high stiffness in compact spaces
