JG400XP0 Bearing Product Overview & Core Advantages
The JG400XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed Bearings series. Engineered with a thin-section design, this sealed bearing offers a compact solution for applications requiring high load capacity in a limited space. Its defining feature is the ability to simultaneously support significant radial loads, axial loads in both directions, and high load moments, making it ideal for demanding, precision applications that demand high reliability and rigidity.
JG400XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JG400 | Indicates the specific bearing series and size designation (40" bore, 42" OD, 1" width). |
| XP0 | Denotes a specific variant, typically indicating sealed construction and pre-lubrication from the factory. |
JG400XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row of balls to support combined radial, axial, and moment loads efficiently, resulting in a compact and lightweight bearing solution with high load capacity.
- Thin-Section & High Rigidity: The Reali-Slim design provides a large diameter in a minimal cross-section, offering exceptional structural rigidity and space savings without compromising performance.
- Sealed & Lubricated for Life: The integrated seals protect against contamination and retain lubricant, enabling maintenance-free operation and extended service life in harsh environments.
- High-Precision Components: Manufactured from Chrome Steel for rings and balls, and featuring a Brass cage, this bearing ensures smooth operation, high-speed capability, and long-term durability. The ABEC-1 tolerance class guarantees consistent and reliable performance.
- Exceptional Load Ratings: Engineered to handle high dynamic and static load ratings (Radial Dynamic: 24,332 lbf, Axial Dynamic: 45,770 lbf) and very high load moments (Dynamic: 374,256 lbf), making it suitable for applications with significant overturning forces.
JG400XP0 Bearing Typical Application Areas
This bearing is specifically designed for large-diameter, low-cross-section applications requiring high moment load capacity. Key industries and equipment include:
- Robotics: Robot rotary joints and arms.
- Aerospace & Defense: Radar bases, gimbal systems, and satellite positioning mechanisms.
- Medical Equipment: CT scanners and MRI machines.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables and precision indexing units.
