NF250XP0 Bearing Product Overview & Core Advantages
The Endura-kote Plated Bearing is a high-performance thin section bearing designed for applications requiring exceptional precision and durability. This single row, four point contact ball bearing is engineered to simultaneously handle significant combined loads, including radial, axial, and moment loads. Featuring a chrome plating coating for enhanced corrosion resistance and a lubricated design, it delivers reliable operation in demanding environments. Its compact thin cross-section (0.75" width) makes it ideal for space-constrained, high-rigidity applications.

NF250XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: This unique geometry enables the bearing to support substantial combined loads – radial, axial, and moment loads – simultaneously, making it exceptionally versatile for complex loading conditions.
High Load Capacity: With a dynamic load moment rating of 115,037 lbf and static load moment of 374,200 lbf, this bearing delivers robust performance under heavy operational stresses.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000 – 0.0005"), it ensures smooth, precise rotation and minimal vibration.
Durable Material Construction: The chrome steel rings and balls, combined with a brass cage, provide excellent strength and wear resistance. The chromium plating further enhances corrosion protection.
Wide Temperature Range: Operates reliably from -30°C to 110°C, suitable for various industrial environments.
NF250XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning systems requiring high moment load capacity.
- Aerospace and Defense: Actuators, control surfaces, and radar systems where reliability and corrosion resistance are critical.
- Medical Equipment: Imaging systems, surgical robots, and diagnostic devices demanding smooth, precise motion.
- Industrial Machinery: Turntables, indexing tables, and other machinery with significant combined loads.
- Semiconductor Manufacturing: Precision stages and handling equipment in cleanroom environments.
