K30020XP0 Bearing Product Overview & Core Advantages
The K30020XP0 is a Four Point Contact Ball Bearing from the Reali-Slim mm Metric Bearings series, designed for applications requiring compact cross-sections and high load capacity. This single row bearing excels at simultaneously handling combined radial loads and axial loads from both directions, making it ideal for space-constrained, high-precision machinery. Manufactured to ABEC-1 precision standards, it delivers reliable performance in demanding industrial environments.
K30020XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Identifies the bearing as part of the Reali-Slim metric series with a thin cross-section. |
| 300 | Bore Diameter: 300 mm |
| 20 | Cross-Section: 20 mm width |
| XP | Four Point Contact design, enabling the bearing to support combined loads. |
| 0 | Open seal type (no shield or seal). |
K30020XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to support significant axial loads in both directions as well as radial loads and moment loads simultaneously, functioning like a combination of two angular contact bearings.
- Thin Section & Lightweight: With a compact 20 mm width and a weight of only 2.3 kg, it enables lightweight, space-saving designs without compromising on load capacity.
- High Load Capacity: Engineered for high static and dynamic load ratings (Radial Static: 16031 lbf, Axial Static: 40076 lbf), providing robust performance under heavy combination loads.
- Precision & Rigidity: Built to ABEC-1 tolerance class with a minimal radial internal clearance (0.0000 – 0.0005"), ensuring high running accuracy and system rigidity.
- Durable Material Construction: Features Chrome Steel rings and balls with a Brass cage for strength, durability, and stable operation.
K30020XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and arm linkages where compact size and moment load capacity are critical.
- Aerospace Actuation Systems: Control surface mechanisms and flight simulator motion platforms.
- Machine Tool Rotaries: Index tables, rotary transfer machines, and CNC rotary attachments.
- Medical Imaging Equipment: Gantries and rotating assemblies in CT and MRI scanners.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages.
