K11008AR0 Bearing Product Overview & Core Advantages
The K11008AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric series, engineered for applications demanding high precision and space-saving designs. Its primary advantage lies in its ability to support combined loads, efficiently handling both radial and significant axial loads in one direction due to its specified 30° contact angle. The bearing features an open design and is pre-lubricated, offering versatility for various configurations. With its thin cross-section and ABEC-1 precision class, it is an ideal solution for compact, high-rigidity assemblies where weight and space are critical constraints.

| Code Segment | Technical Meaning |
|---|---|
| K | Designates the bearing as part of the Reali-Slim metric thin-section series. |
| 11008 | Indicates the nominal bore diameter (110 mm) and cross-section size. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies a standard radial internal clearance and potentially other standard features for the series. |
K11008AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 30° contact angle provides excellent rigidity and is specifically engineered to support high combined loads, including substantial one-direction axial loads.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, ensuring predictable performance and ease of integration into precision assemblies.
- Durable Material Construction: Components made from Chrome Steel rings and balls, combined with a Brass cage, offer high strength, wear resistance, and reliable operation.
- Space-Saving Design: As a thin section bearing with a width of only 8 mm, it enables lightweight and compact machinery designs without sacrificing performance.
- Pre-Lubricated & Wide Temperature Range: Comes pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C.
