JG300XM0 Bearing Product Overview & Core Advantages
The Reali-Slim Sealed Bearing represents a specialized thin section bearing solution engineered for applications demanding compact design and high performance. This four point contact ball bearing is uniquely capable of simultaneously supporting radial loads, axial loads in both directions, and moment loads, making it an ideal choice for space-constrained, high-precision machinery. Its sealed construction and pre-lubrication ensure long-term reliability and reduced maintenance requirements.
JG300XM0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation | Technical Significance |
|---|---|---|
| Series | Reali-Slim | Indicates a thin section bearing with a cross-section that is slim relative to its bore diameter. |
| Seal Type | Sealed | Integrated seals protect against contamination and retain lubricant, enhancing service life. |
| Load Direction | Four Point Contact | The raceway geometry allows the bearing to handle combined loads efficiently in a single bearing row. |
| Tolerance Class | ABEC-1 | Specifies standard precision level for dimensional accuracy and running performance. |
JG300XM0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a slim 1" width and a large 30" bore, this bearing maximizes space utilization and reduces overall system weight, critical in robotics and aerospace applications.
- Superior Load Capacity: The four point contact design enables exceptional performance under combined radial, axial, and moment loads. It offers a high dynamic load moment of 246,541 lbf and a static load moment of 788,800 lbf.
- High Rigidity & Precision: Manufactured to ABEC-1 tolerances with tight internal clearance (0.0000 – 0.0005"), it provides precise rotational accuracy and high rigidity for stable operation.
- Durability & Corrosion Resistance: Components made from Chrome Steel (rings and balls) and a Stainless Steel cage ensure high durability and resistance to corrosion.
- Maintenance-Free Operation: The integral seals and factory-applied lubrication allow for extended service intervals, ideal for hard-to-reach locations.
JG300XM0 Bearing Typical Application Areas
This bearing is specifically designed for applications where a large diameter must be accommodated with a minimal cross-section. Key industries and equipment include:
- Robotics: Robot joints and rotary actuators.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Machine Tool: Rotary tables, indexers, and CNC positioning stages.
- Medical Equipment: CT scanners and MRI equipment.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
