ND120XP0 Bearing Product Overview & Core Advantages
The ND120XP0 is a four-point contact ball bearing featuring Endura-kote chromium plating for enhanced corrosion resistance. Engineered as a single-row thin section bearing with inch dimensions, it delivers exceptional performance in applications requiring high moment load capacity within compact spaces. Its four-point contact design enables it to simultaneously handle combined radial and axial loads from any direction, making it ideal for precision rotational systems demanding high rigidity and reliable operation.

ND120XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique ball-raceway configuration provides exceptional moment load capacity (19 ft-lbf rated load moment) while maintaining compact bearing dimensions (12" bore × 13" OD × 0.5" width).
High Load Capacity: Engineered to handle significant combined loads with dynamic ratings of 4178 lbf radial and 6950 lbf axial, supported by chrome steel construction for durability.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with minimal radial internal clearance (0.0000-0.0005") for precise rotational accuracy and smooth operation.
Corrosion Resistance: Endura-kote chromium plating provides enhanced protection against corrosion, extending service life in challenging environments.
Optimized Cage Design: Brass cage material ensures reliable ball guidance and stable operation across the temperature range of -30°C to 110°C.
ND120XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints and positioning systems requiring high moment stiffness
- Aerospace Equipment: Actuator mechanisms and control surface assemblies
- Medical Imaging Systems: Gantry rotations and precision scanning equipment
- Industrial Machinery: Turntables, indexing tables, and rotational workstations
