KB200XP0 Bearing Product Overview & Core Advantages
The KB200XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed for applications demanding compact cross-sections and high load capacity. As a thin section bearing, it features a single row design that can simultaneously support combined radial and axial loads from any direction. Manufactured to ABEC-1 precision tolerances, it is engineered for high reliability in space-constrained, high-performance machinery. Its open construction allows for custom lubrication schemes to meet specific operational requirements.
KB200XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KB200XP0 | Specific model identifier for this thin-section, four-point contact bearing. |
| Open | Indicates the bearing has no integral seals or shields, allowing for direct lubrication and custom sealing solutions. |
| Four Point Contact | Denotes the ball-raceway contact geometry, enabling the bearing to handle combined loads and moment loads efficiently in a compact design. |
KB200XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity in a Slim Profile: The four-point contact design and large 20" bore enable this thin section bearing to support significant radial dynamic load ratings of 2731 lbf and exceptional axial static load ratings of 20620 lbf, along with a high static load moment of 83780 lbf.
- Precision and Rigidity: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance, ensuring smooth, precise operation and minimal runout for accurate positioning.
- Robust Material Construction: Features rings and balls made from Chrome Steel for high durability and wear resistance, combined with a Brass cage for excellent stability and guidance at moderate speeds.
- Versatile Operating Range: With a temperature range of -30°C to 110°C and a pre-lubricated design, it is suitable for a wide array of industrial environments.
KB200XP0 Bearing Typical Application Areas
- Robotics: Ideal for robotic joints and actuators where high moment load capacity and a compact design are critical.
- Aerospace & Defense: Used in gimbal systems, radar platforms, and flight control mechanisms requiring precision and reliability.
- Medical Equipment: Suitable for advanced imaging systems (MRI, CT scanners) and surgical robots demanding smooth, precise motion.
- Semiconductor Manufacturing: Applied in wafer handling and precision positioning stages within cleanroom environments.
- Industrial Automation: Perfect for rotary tables, indexing heads, and other machinery where space is limited and combined loads are present.
