K25008XP0 Bearing Product Overview & Core Advantages
The K25008XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding high precision and space optimization. This single-row bearing excels in handling combined loads, simultaneously supporting significant radial loads and axial loads from both directions. Its compact cross-section, with an 8mm width and 250mm bore, makes it ideal for high-rigidity support in weight-sensitive designs. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in precision instruments and rotational mechanisms.
K25008XP0 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. |
| 25008 | Specifies the core dimensions: 250mm bore diameter and 8mm width. |
| XP0 | Denotes a specific internal configuration, likely referring to the Four Point Contact design and potentially a standard radial internal clearance. |
K25008XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The single-row, angular contact geometry allows the bearing to efficiently support combined radial and axial loads from both directions, simplifying assembly and reducing the need for multiple bearing sets.
- High Rigidity & Precision: The ABEC-1 tolerance class and robust construction with a brass cage provide stable, precise rotation, minimizing runout and enhancing system accuracy.
- Space & Weight Savings: As a thin-section bearing, it offers a large bore diameter relative to its cross-section, enabling compact and lightweight machinery designs without sacrificing performance.
- Durable Material Construction: Components made from Chrome Steel offer high hardness and wear resistance, ensuring a long operational life under dynamic and static loads.
- Optimized Load Capacity: Engineered for high static load moments (1075 ft-lbf), making it suitable for applications with significant overturning forces.
K25008XP0 Bearing Typical Application Areas
This bearing is designed for high-performance applications where space, weight, and precision are critical. Key industries and equipment include:
- Robotics: Rotary joints and actuators.
- Aerospace & Defense: Gimbals, radar platforms, and control surfaces.
- Machine Tool: Rotary tables and indexing heads.
- Medical Equipment: CT scanners and precision rotational stages.
- Semiconductor Manufacturing: Wafer handling and precision positioning systems.
