KD040XP0 Bearing Product Overview & Core Advantages
The KD040XP0 is a high-performance thin section bearing designed for applications demanding space optimization 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, compact bearing row. Manufactured to ABEC-1 precision tolerances, it offers reliable operation and is pre-lubricated for immediate use, making it an ideal choice for high-rigidity and weight-sensitive systems.

KD040XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry allows the bearing to support significant combined loads (radial, axial, and moment loads) efficiently, replacing the need for more complex bearing arrangements and saving space.
Thin Section Construction: With a consistent 0.5" cross-section, this bearing minimizes weight and envelope size without compromising on load capacity, making it perfect for compact machinery.
High-Precision Components: Manufactured from Chrome Steel for rings and balls, and featuring a Brass cage, the bearing ensures smooth operation, reduced vibration, and long service life under ABEC-1 precision standards.
Optimized Load Ratings: Engineered for high performance with a dynamic load moment rating of 3901 lbf and a static load moment of 6930 lbf, providing robust support in demanding applications.
KD040XP0 Bearing Typical Application Areas
- Robotics and automation arms (for joint and pivot points)
- Aerospace control mechanisms and actuation systems
- Medical Equipment such as CT scanners and surgical robots
- Semiconductor Manufacturing equipment requiring precise motion control
- Radar and Antenna positioning systems
