K02508XP0 Bearing Product Overview & Core Advantages
The K02508XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding high precision and space optimization. As a single-row bearing with an open design, it is specifically configured to handle combined radial and axial loads from any direction simultaneously. Its compact cross-section, with a width of only 8 mm, makes it an ideal solution for lightweight, high-rigidity assemblies where minimizing envelope size is critical. Manufactured to ABEC-1 precision tolerances, this bearing ensures reliable performance in demanding motion control systems.
K02508XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K025 | Indicates the Reali-Slim metric series with a specific cross-section (8mm). |
| 08 | Specifies the bore diameter of 25 mm. |
| XP | Denotes the Four Point Contact ball raceway design. |
| 0 | Signifies an open (unsealed) construction. |
K02508XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry allows the bearing to support significant combined radial and axial loads in both directions with a single bearing row, simplifying assembly and reducing part count.
- High Rigidity & Precision: The thin-section construction combined with ABEC-1 precision tolerances and tight dimensional controls (bore and OD tolerance: -0.01mm to 0) ensures minimal deflection and accurate rotational performance.
- Optimized Material Selection: Components made from Chrome Steel (rings and balls) and a Brass cage provide excellent durability, corrosion resistance, and smooth operation at moderate speeds.
- Broad Operating Range: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, making it suitable for various industrial environments.
K02508XP0 Bearing Typical Application Areas
This bearing is ideally suited for compact and precision mechanisms, including:
- Robotics (joints and rotary actuators)
- Aerospace control systems and instrumentation
- Medical Equipment (scanners, rotary tables)
- Semiconductor Manufacturing equipment
- Precision Rotary Stages and indexing tables
