KC200XP0 Bearing Product Overview & Core Advantages
The KC200XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered with an ultra-thin cross-section and single row construction, it delivers exceptional load capacity in a compact, space-saving design. This bearing is specifically designed to simultaneously handle significant combined radial and axial loads from any direction, making it an ideal solution for applications requiring high precision and structural rigidity where space and weight are critical constraints.
KC200XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC200XP0 | Specific manufacturer model designation for this thin-section bearing. |
| Open | Indicates an unsealed construction, allowing for custom lubrication schemes and high-speed operation. |
| Four Point Contact | The core design feature enabling the bearing to support combined loads and moment loads efficiently. |
| ABEC-1 | Specifies the tolerance class, ensuring consistent precision and performance for general industrial applications. |
KC200XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows each ball to make contact at four points, enabling the bearing to support substantial axial loads in both directions, radial loads, and moment loads (Dynamic Load Moment: 26,695 lbf) with a single bearing row, simplifying assembly and saving space.
- High Load Capacity & Rigidity: Despite its thin section, the use of Chrome Steel for rings and balls, combined with a robust Brass cage, provides high static and dynamic load ratings (Radial Dynamic: 3,492 lbf, Axial Static: 24,500 lbf), ensuring stable and precise operation under heavy loads.
- Precision & Reliability: Manufactured to ABEC-1 tolerances with a controlled radial internal clearance (0.0000" – 0.0005"), this bearing guarantees smooth running and accurate positioning, which is critical for precision machinery.
- Versatile Lubrication & Temperature Range: The open design allows for the use of specialized lubricants, supporting operation within a broad temperature range of -30°C to 110°C.
KC200XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications demanding a large diameter, slim profile, and high load capacity. Key industries and equipment include:
- Robotics: Rotary joints and actuators.
- Aerospace: Control mechanisms, radar platforms, and gyro gimbals.
- Machine Tool: Rotary tables, indexing heads, and pallet changers.
- Medical Equipment: CT and MRI scanner gantries.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
