KD070XP0 Bearing Product Overview & Core Advantages
The KD070XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered with an ultra-thin cross-section (Width: 0.5"), it delivers exceptional space and weight savings without compromising performance. This single-row bearing is specifically designed to handle combined radial and axial loads simultaneously from any direction, making it an ideal solution for applications requiring high precision and rigidity in a compact envelope. Its ABEC-1 precision and optimized internal geometry ensure reliable operation and long service life.
KD070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD070 | Bearing series designation for Reali-Slim open type bearings. |
| XP0 | Indicates specific internal design and performance features, including the Four Point Contact geometry for superior moment load capacity. |
| Open | No integral seals or shields, allowing for high-speed operation and custom lubrication schemes. |
KD070XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to support combined radial, axial, and moment loads efficiently. This results in a high Dynamic Load Moment rating of 8730 lbf and a Static Load Moment of 19240 lbf, providing exceptional stability.
- Ultra-Thin Section: With a consistent cross-section (0.5" width) across large bore sizes (7"), it enables compact, lightweight machinery design, significantly reducing overall system weight and envelope.
- High-Precision Components: Manufactured from Chrome Steel rings and balls with a Brass cage, the bearing ensures smooth operation, high-speed capability, and extended fatigue life. The ABEC-1 tolerance class guarantees consistent running accuracy.
- Optimized Internal Clearance: The specified Radial Internal Clearance (0.0000 – 0.0005") is pre-set to ensure optimal performance under operational temperatures and loads, minimizing noise and vibration.
KD070XP0 Bearing Typical Application Areas
The KD070XP0's unique combination of a large bore, thin section, and high moment load capacity makes it indispensable in:
- Robotics: Rotary joints and actuator arms where space and weight are critical.
- Aerospace & Defense: Gimbals, radar platforms, and control surface actuators.
- Machine Tool: Rotary tables, indexers, and other precision positioning systems.
- Medical Equipment: CT scanner gantries and surgical robot joints requiring smooth, precise motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
