KA075XP0 Bearing Product Overview & Core Advantages
The KA075XP0 is a high-precision thin section bearing designed for applications requiring maximum space efficiency without compromising performance. As a Four Point Contact ball bearing, it excels at handling combined loads—simultaneously supporting substantial radial loads and bidirectional axial loads. Its ABEC-1 precision classification and optimized internal geometry ensure smooth operation and high positional accuracy in compact designs. The open construction allows for custom lubrication schemes, while the brass cage contributes to stable operation across its specified temperature range.
KA075XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA075 | Bearing series designation for thin-section, four-point contact bearings with 7.5" bore diameter |
| X | Indicates extra capacity design with optimized raceway geometry |
| P0 | Standard precision grade (equivalent to ABEC-1) |
KA075XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry enables the bearing to handle combined radial and axial loads from any direction, making it ideal for applications with complex loading conditions. The contact angle optimization provides excellent moment load capacity (3 ft-lbf rated load moment).
Thin-Section Construction: With a consistent 0.25" cross-section regardless of bearing size, this design maximizes space utilization while maintaining structural integrity. The precision bearing dimensions ensure consistent performance and easy integration into compact assemblies.
High-Capacity Materials: Chrome steel rings and balls provide superior wear resistance and fatigue life, while the brass cage ensures smooth operation at various speeds and temperatures. The combination delivers reliable performance with dynamic load ratings of 1089 lbf (radial) and 1810 lbf (axial).
Precision Engineering: Manufactured to ABEC-1 standards with tight bearing dimensional tolerances (±0.0012" on diameters) and controlled radial internal clearance (0.0000-0.0005"), ensuring predictable performance and long service life.
