NC120XP0 Bearing Product Overview & Core Advantages
The NC120XP0 is a four-point contact ball bearing engineered for applications requiring exceptional moment load capacity and compact design. Featuring a thin-section single row construction with a durable Endura-kote plating, this bearing is optimized to handle significant combined radial, axial, and moment loads simultaneously. Its inch dimensions and ABEC-1 precision make it an ideal, high-reliability component for space-constrained, high-performance systems.

| NC120 | Bearing series and size designation (12" Bore, 12.75" OD) |
| XP0 | Specific variant indicating Endura-kote Plated surface and Open (unsealed) construction. |
NC120XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The optimized raceway geometry allows a single row bearingcombined moment loads (12 ft-lbf rated), radial loads (2622 lbf dynamic), and axial loads (4420 lbf dynamic) from both directions, simplifying assembly and reducing part count.
- Thin-Section & High Rigidity: With a cross-section of only 0.375", this bearing offers a high load capacity within a minimal envelope, contributing to system compactness and high rigidity.
- Endura-kote Chromium Plating: The advanced surface coating enhances corrosion resistance and wear characteristics, extending service life in demanding environments.
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise operation and consistent performance.
- Robust Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage provide excellent durability and reliable operation across a wide temperature range (-30°C to 110°C).
NC120XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high moment load capacity and a compact form factor, including:
- Robotics (Rotary Joints & Actuators)
- Aerospace & Defense Systems (Gimbals, Turrets)
- Semiconductor Manufacturing Equipment
- Medical Imaging and Diagnostic Devices
- High-Precision Rotary Tables and Indexers
