KD047XP0 Bearing Product Overview & Core Advantages
The KD047XP0 is a Four Point Contact thin section bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim Open Bearings series with an inch system of measurement, it features a single row construction that provides exceptional load capacity in a compact cross-section. Its primary advantage is the ability to simultaneously support significant radial loads, axial loads in both directions, and moment loads, making it an ideal solution for high-rigidity applications where weight and space are critical constraints.

| X | Cross-section series designation |
| P | Four Point Contact design |
| 0 | Open (unsealed) construction |
KD047XP0 Bearing Structural Features & Performance Benefits
The KD047XP0 achieves its superior performance through several key structural features:
- Four Point Contact Design: The raceway geometry enables the bearing to handle combined loads efficiently, including radial, bidirectional axial, and moment loads from a single bearing position.
- Thin Section Construction: With a consistent 0.5" width across all diameters, this design minimizes weight and space requirements while maintaining structural integrity.
- Premium Materials: Chrome steel rings and balls with a brass cage provide excellent durability and smooth operation under various loading conditions.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (0.0000 – 0.0005") for consistent performance in precision applications.
- High Load Capacity:
- Radial dynamic: 2,496 lbf | Static: 3,530 lbf
- Axial dynamic: 3,860 lbf | Static: 8,840 lbf
- Dynamic moment: 4,916 lbf | Static moment: 9,280 lbf
KD047XP0 Bearing Typical Application Areas
The KD047XP0 thin section bearing is ideally suited for applications requiring compact design and high load capacity:
- Robotics and automation systems (joints, rotary actuators)
- Aerospace components (control mechanisms, satellite systems)
- Medical equipment (imaging systems, surgical robots)
