KD180XP0 Bearing Product Overview & Core Advantages
The KD180XP0 is a high-performance thin section bearing designed for applications requiring maximum space utilization and precision. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction with a single bearing row. Its open design and ABEC-1 precision make it ideal for compact, high-rigidity systems where weight and cross-section are critical constraints. Manufactured from chrome steel components and featuring a durable brass cage, this bearing delivers reliable performance in demanding operational environments.

KD180XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables this single-row bearing to support radial loads, axial loads in both directions, and moment loads simultaneously, eliminating the need for multiple bearing arrangements and saving valuable space.
Thin Section Construction: With a consistent 0.5-inch width and minimal cross-section, this bearing maximizes the available design envelope while maintaining structural integrity, making it perfect for compact machinery and weight-sensitive applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and OD tolerance: -0.0018" to 0"), this bearing ensures smooth operation and accurate positioning in precision equipment.
Durable Material Selection: Chrome steel rings and balls provide excellent wear resistance and fatigue life, while the brass cage ensures stable ball guidance and reliable performance at moderate speeds.
Optimized Load Capacity: The design delivers a dynamic load rating of 5226 lbf and static load rating of 12650 lbf, providing substantial load-bearing capability despite its slim profile.
