KG300XP0 Bearing Product Overview & Core Advantages
The KG300XP0 is a high-performance **Four Point Contact Ball Bearing** from the **Reali-Slim Open Bearings** series, designed with an ultra-thin cross-section to save space and weight in demanding applications. Engineered to simultaneously handle significant **combined radial and axial loads** from any direction, this **precision bearing** offers exceptional rigidity and load capacity in a compact design. Its **ABEC-1 tolerance class** ensures reliable performance for applications requiring high positional accuracy and smooth operation.
KG300XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG300XP0 | Specific model identifier for this thin-section, four-point contact bearing. |
| Open (Construction) | No integral seals or shields, allowing for custom lubrication schemes and maximum speed capability. |
| Four Point Contact | The ball raceway geometry is designed to support axial loads in both directions as well as radial loads, functioning like a pair of angular contact bearings. |
KG300XP0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row, four-point contact design provides high stiffness and can support substantial combined loads, with a dynamic load moment rating of 246,541 lbf and a static load moment of 788,800 lbf.
- Precision Engineering: Manufactured to ABEC-1 precision standards with a tight radial internal clearance (0.0000" – 0.0005") for smooth, precise rotation and reduced runout.
- Durable Material Construction: Features rings and balls made from high-carbon Chrome Steel for extended service life and a Brass cage for superior guidance and stability at high speeds.
- Optimized Thin-Section Design: With a cross-section of just 1", it enables lightweight, compact machinery designs without sacrificing performance.
KG300XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space is constrained and high moment loads are present. Key industries and equipment include:
- Robotics: Rotary joints and arms.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Machine Tool: Rotary tables, indexers, and CNC positioning systems.
- Medical Equipment: CT scanners and MRI systems.
- Semiconductor Manufacturing: Precision wafer handling and staging equipment.
