NG200AR0 Bearing Product Overview & Core Advantages
The NG200AR0 is a high-performance thin section angular contact ball bearing designed for applications demanding exceptional precision and load capacity. Featuring a single row construction with a generous 30° contact angle, this bearing is engineered to efficiently support combined loads, handling significant radial and axial forces simultaneously. Its Endura-kote chromium plating enhances corrosion resistance, while the ABEC-1 precision class ensures reliable operation in high-accuracy systems. With its large 20-inch bore and compact cross-section, it is an ideal solution for space-constrained, high-rigidity applications requiring long-term performance.
NG200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NG200 | Bearing series designation, indicating a thin-section, large bore angular contact bearing. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Indicates standard radial internal clearance and potentially a specific internal design or cage type (in this context, a brass cage). |
NG200AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides superior stiffness and is capable of supporting high combined radial and axial loads, as evidenced by its 13,612 lbf dynamic and 39,810 lbf static radial load ratings.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bore and outside diameter (tolerance: -0.0018" to 0"), ensuring smooth, precise operation and ease of installation.
- Durable Material & Construction: Components made from chrome steel (rings and balls) and a brass cage offer high strength, wear resistance, and operational stability. The Endura-kote chromium plating significantly improves corrosion resistance.
- Optimized for Performance: The pre-defined radial internal clearance (0.0000 – 0.0005") and factory lubrication are selected to deliver optimal performance within the specified temperature range of -30°C to 110°C.
NG200AR0 Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty, precision applications, including:
- Large-Diameter Rotary Tables and Indexing Heads
- Precision Gearboxes and Drivetrain Systems
- Aerospace Actuation Systems and Flight Control Mechanisms
- Industrial Robotics (e.g., large robot joints)
- Medical Imaging Equipment (e.g., CT scanner gantries)
- Semiconductor Manufacturing Equipment
