KG400XP0 Bearing Product Overview & Core Advantages
The Reali-Slim Open Bearing represents a specialized class of thin section bearings engineered for applications demanding compact design and high load capacity within a minimal cross-section. This Four Point Contact ball bearing is designed to simultaneously handle significant radial loads, axial loads in both directions, and moment loads, making it an ideal solution for space-constrained, high-performance machinery. Manufactured to ABEC-1 precision standards, it offers reliable performance in robotic arms, aerospace systems, and precision rotary tables.
KG400XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Code/Value | Technical Significance |
|---|---|---|
| Bearing Series | Reali-Slim | Denotes a thin section bearing with a standardized, slim cross-section. |
| Seal Type | Open | No integral seals, allowing for custom sealing solutions and higher speed potential. |
| Contact Type | Four Point Contact | The ball raceway geometry allows the bearing to support combined loads (radial, axial, moment) efficiently in a single row. |
| Precision Class | ABEC-1 | Standard precision grade ensuring consistent running accuracy and smooth operation. |
KG400XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: A single row of balls contacts the raceways at four points, enabling the bearing to handle combined radial, axial, and moment loads without the need for multiple bearing arrangements. This simplifies design and saves space.
- High Load Capacity in a Slim Profile: Despite its thin 1" cross-section (Width), the bearing offers impressive dynamic and static load ratings (Radial Dynamic: 24,332 lbf, Axial Dynamic: 45,770 lbf), a direct result of its optimized internal geometry and high-strength materials.
- Superior Moment Load Capacity: The design is specifically optimized to resist tilting moments, with a high Dynamic Load Moment rating of 374,256 lbf·in, making it exceptionally rigid under complex loading conditions.
- Premium Material Construction: The use of Chrome Steel for rings and balls, combined with a Brass cage, ensures high durability, wear resistance, and stable operation at various speeds.
- Pre- Lubricated: Comes lubricated from the factory, reducing initial setup time and ensuring immediate, smooth operation.
KG400XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuators in robotic arms where compact size, high rigidity, and multi-directional load capacity are critical.
- Aerospace & Defense: Gimbals, radar platforms, and flight control mechanisms requiring precise motion and reliability.
- Machine Tool & Automation: Rotary tables, indexers, and CNC positioning stages.
- Medical Equipment: Imaging systems (CT/MRI scanners) and surgical robots.
- Semiconductor Manufacturing: Wafer handling and precision positioning equipment.
