JA070XP0 Bearing Product Overview & Core Advantages
The JA070XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed Bearings series. Engineered with an inch system of measurement, this single row bearing is specifically designed to handle significant combined loads, including radial, axial, and moment loads simultaneously. Its ultra-thin cross-section (Width: 0.25") combined with a sealed construction makes it an ideal solution for applications demanding high rigidity and compact design in a precision ABEC-1 package. This bearing offers a superior balance of load capacity and long service life in challenging environments.
JA070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| JA070 | Bearing series designation for Reali-Slim sealed type | Identifies the thin-section, high-capacity family |
| XP0 | Specific variant code within the series | Defines exact internal configuration and performance grade |
| Sealed (Construction) | Integrated seals to protect the bearing interior | Contaminant exclusion, pre-lubricated for life, reduced maintenance |
| Four Point Contact | Raceway geometry allowing ball contact at four points | Enables handling of combined radial, axial, and moment loads in a single bearing |
JA070XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows each ball to make contact at four points, enabling the bearing to support substantial combined loads—radial (1046 lbf dynamic), axial (1730 lbf dynamic), and moment loads (2844 lbf dynamic)—efficiently in a compact, single-row design.
- Thin-Section & High Rigidity: With a cross-section of just 0.25", this bearing saves critical space and weight (0.31 lbs) without compromising structural integrity, providing high rigidity support for precision mechanisms.
- Sealed & Pre-Lubricated Construction: The integrated seals protect against contaminants, and the bearing comes pre-lubricated, offering a maintenance-free solution suitable for the specified operating temperature range of -30°C to 110°C.
- Precision Components: Manufactured from Chrome Steel for rings and balls, and featuring a Brass cage, the bearing ensures smooth operation, durability, and consistent performance under the ABEC-1 precision class.
JA070XP0 Bearing Typical Application Areas
The JA070XP0 is engineered for compact, high-load machinery where space is at a premium and reliability is critical. Key application areas include:
- Robotics: Rotary joints, arm actuators, and precision gearboxes.
- Aerospace & Defense: Actuation systems, radar platforms, and guidance systems.
- Medical Equipment: Surgical robots, imaging devices (CT/MRI scanners), and diagnostic instruments.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and indexing tables.
- Industrial Automation:
- Rotary tables and indexing drives
- Pitch and yaw drives
