JA075XP0 Bearing Product Overview & Core Advantages
The JA075XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed series, engineered for applications requiring exceptional thin section design and compactness. This sealed bearing is designed to simultaneously handle significant combined loads, including radial, axial, and moment loads, making it an ideal solution for space-constrained, high-precision machinery. Its inch-system dimensions (7.5" bore, 8" OD, 0.25" width) and ABEC-1 precision ensure reliable performance in demanding environments.
JA075XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JA075XP0 | Base model number indicating a specific thin-section, sealed bearing design. |
| Sealed | Integral seals to protect against contamination and retain lubrication. |
| Four Point Contact | The ball-to-raceway contact geometry enables the bearing to support combined radial, axial, and moment loads in a compact cross-section. |
| Lubricated | Pre-lubricated from the factory for immediate service and extended maintenance intervals. |
JA075XP0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a thin 0.25" cross-section and a weight of only 0.34 lbs, the bearing minimizes system size and inertia, crucial for high-speed applications.
- Superior Load Capacity: The Four Point Contact design provides excellent combined load handling, with a dynamic radial load rating of 1089 lbf and a dynamic axial load rating of 1810 lbf. It is uniquely capable of supporting substantial load moments (Dynamic: 3165 lbf, Static: 9120 lbf).
- High Rigidity & Precision: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000 – 0.0005"), ensuring precise shaft positioning and high rigidity.
- Enhanced Service Life & Reliability: The sealed construction and pre-applied lubrication protect against contaminants and provide long-term, maintenance-free operation within a temperature range of -30°C to 110 °C. The brass cage contributes to smooth operation and durability.
JA075XP0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Robotics: Rotary joints and actuator arms where compactness and moment load capacity are critical.
- Aerospace & Defense: Guidance systems, radar platforms, and gimbal mechanisms.
- Medical Equipment: CT scanners, surgical robots, and other precision imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and other high-precision motion control systems.
