KD075XP0 Bearing Product Overview & Core Advantages
The KD075XP0 is a high-performance thin section bearing designed for applications requiring exceptional precision and space optimization. As a Four Point Contact Ball Bearing with single row construction, it efficiently handles combined loads including radial, axial, and moment loads simultaneously. Manufactured to ABEC-1 precision standards with inch measurements (7.5" bore × 8.5" OD × 0.5" width), this bearing delivers reliable performance in compact envelope designs where weight reduction and high rigidity are critical requirements.
KD075XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| KD075 | Bore diameter identification (7.5 inches) | Standardized inch sizing for compatibility |
| XP0 | Specific series designation for thin section open bearings | Optimized cross-section for space-constrained applications |
| Open Construction | No seals or shields | Allows for custom lubrication schemes and high-speed operation |
KD075XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support radial loads (3,222 lbf dynamic), axial loads (5,160 lbf dynamic), and significant moment loads (9 ft-lbf rated) simultaneously, eliminating the need for multiple bearing arrangements.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0012" to 0") and minimal radial internal clearance (0.0000" - 0.0005") for precise rotational accuracy and reduced vibration.
Premium Material Construction: Chrome steel rings and balls provide excellent wear resistance and fatigue life, while the brass cage ensures stable ball guidance and reliable high-speed operation.
Optimized Cross-Section: With only 0.5" width and thin-section design, this bearing offers significant weight savings (1.41 lbs) while maintaining high rigidity and load capacity in compact spaces.
