J07008XP0 Bearing Product Overview & Core Advantages
The J07008XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding compact design and high precision. As part of the Reali-Slim mm Metric Bearings series, it offers a superior cross-section-to-diameter ratio, enabling significant space and weight savings. Its four-point contact design allows it to support combined radial and axial loads from any direction with a single bearing, simplifying assembly and enhancing system rigidity. Manufactured to ABEC-1 precision and pre-lubricated, it delivers reliable performance in high-accuracy, compact mechanisms.
J07008XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| J07008 | Denotes the bearing series (Reali-Slim) with a 70mm bore and 8mm width. |
| XP0 | Indicates a sealed construction and specific internal configuration for four-point contact. |
J07008XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact & High Rigidity: The single-row design with a four-point contact geometry provides high moment stiffness, enabling the bearing to resist load moments effectively, making it ideal for applications with overturning forces.
- Superior Load Capacity: Engineered to handle combined radial and axial loads simultaneously. With a dynamic load moment rating of 36 lbf-in and a static load moment of 65 lbf-in, it offers robust performance under complex loading conditions.
- Precision & Smooth Operation: Built to ABEC-1 tolerance classes with a tight radial internal clearance (0.0000 – 0.0005 inches), ensuring smooth, precise rotation and minimal runout.
- Sealed & Lubricated for Life: The sealed design with pre-applied lubricant protects against contamination and provides long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
J07008XP0 Bearing Typical Application Areas
This bearing is ideally suited for compact, high-precision systems including:
- Robotics (joints and actuators)
- Aerospace and defense gimbal systems
- Medical equipment (scanners, rotary tables)
- Semiconductor manufacturing machinery
- Precision rotary stages and indexing tables
