KD140XP0 Bearing Product Overview & Core Advantages
The KD140XP0 is a high-performance thin section bearing designed for applications requiring maximum load capacity in minimal space. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction. Its inch-series design with a large 14" bore and remarkably slim 0.5" cross-section makes it ideal for compact, weight-sensitive assemblies in robotics, aerospace, and precision machinery, offering an exceptional strength-to-size ratio.

KD140XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry allows the bearing to support combined radial, axial, and moment loads efficiently in a single bearing, simplifying system design and reducing component count.
High Load Capacity: Engineered for demanding applications, it delivers exceptional static and dynamic load ratings (Radial Static: 9920 lbf, Axial Static: 24800 lbf) despite its slim profile.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on bore diameter, outside diameter, and width, ensuring consistent performance and easy installation.
Premium Materials: Constructed with Chrome Steel rings and balls and a Brass cage for durability, corrosion resistance, and reliable operation across a wide temperature range (-30°C to 110°C).
KD140XP0 Bearing Typical Application Areas
- Robotics: Rotary joints, robot arms, and end-effectors requiring high moment load capacity
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms
- Medical Equipment: CT scanners, MRI systems, and surgical robot positioning stages
- Semiconductor Manufacturing: Wafer handling robots and precision positioning tables
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes
