K18008XP0 Bearing Product Overview & Core Advantages
The K18008XP0 is a metric thin-section four-point contact ball bearing engineered for applications requiring high precision and compact design. As a single-row bearing with four-point contact design, it efficiently handles combined radial and axial loads from any direction simultaneously. Its ultra-thin cross-section (8mm width) enables significant space and weight savings while maintaining excellent rotational accuracy, making it ideal for high-rigidity applications where structural compactness is critical.
K18008XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| K18008 | Basic bearing designation with 180mm bore diameter | Standard size identification for proper selection |
| XP0 | Specific internal design and tolerance class | Optimized for precision applications with ABEC-1 tolerance |
Structural Features & Performance Advantages
Four-Point Contact Design: The unique raceway geometry allows the bearing to support combined radial and axial loads from any direction, providing exceptional load-carrying capacity in a compact package.
Thin-Section Construction: With only 8mm width and minimal cross-section, this bearing delivers space-saving advantages while maintaining structural integrity and high rigidity.
Precision Engineering: Manufactured to ABEC-1 tolerance class with chrome steel rings and balls, ensuring consistent performance and long service life in precision applications.
Enhanced Load Ratings: Features impressive dynamic load ratings (2074 lbf radial, 3296 lbf axial) and static load ratings (4118 lbf radial, 10297 lbf axial) relative to its compact dimensions.
Brass Cage Construction: The brass cage provides excellent dimensional stability and reliable ball guidance, contributing to smooth operation and extended bearing life.
