K20008XP0 Bearing Product Overview & Core Advantages
The K20008XP0 is a metric thin-section bearing engineered for applications demanding high precision and space-saving designs. As a Four Point Contact Ball Bearing with a single row construction, it is uniquely capable of simultaneously supporting combined radial and axial loads from any direction. Its remarkably slim cross-section, with a width of only 8 mm, makes it an ideal solution for compact assemblies where high load capacity and rigidity are critical. Manufactured to ABEC-1 tolerance standards, this bearing ensures reliable performance in high-precision machinery.
K20008XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a specific series or design variant within the Reali-Slim metric bearing family. |
| 20008 | Specifies the bore diameter (200 mm) and the cross-section series (08, indicating an 8 mm width). |
| XP | Denotes a Four Point Contact ball bearing design. |
| 0 | Typically indicates an Open (non-shielded/non-sealed) configuration and standard internal clearance. |
K20008XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row of balls to support radial loads, axial loads in both directions, and moment loads simultaneously, effectively replacing the need for complex bearing arrangements.
- High Load Capacity: Engineered with chrome steel rings and balls, this bearing offers a high dynamic load rating (2187 lbf radial, 3501 lbf axial) and static load rating (4508 lbf radial, 11272 lbf axial) for its compact size.
- Precision & Rigidity: Built to ABEC-1 precision standards with tight dimensional tolerances, it provides excellent running accuracy and contributes to overall system stiffness.
- Lightweight & Compact: The thin-section design (8mm width) and use of a brass cage result in a lightweight component (0.22 kg) that minimizes inertia and saves critical space.
- Standard Lubrication: Comes pre-lubricated for immediate use, suitable for the specified temperature range of -30°C to 110°C.
K20008XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a large diameter with a minimal cross-section and the ability to handle combined loads. Key industries and equipment include:
- Robotics: Rotary joints and actuators.
- Aerospace & Defense: Gimbal systems, radar platforms, and control surfaces.
- Medical Equipment: CT scanners and MRI machines.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical Instrumentation: Rotary tables and positioning devices.
