NG220AR0 Bearing Product Overview & Core Advantages
The NG220AR0 is a single row angular contact ball bearing designed for high-performance applications requiring exceptional precision and reliability. Manufactured to ABEC-1 tolerance class, this bearing delivers outstanding dimensional accuracy and rotational precision. Its 30° contact angle enables superior handling of combined radial and axial loads, while the Endura-kote chromium plating provides enhanced corrosion resistance and durability. The bearing's inch dimensions (22" bore × 24" OD × 1" width) make it ideal for heavy-duty industrial equipment where precise fit and reliable operation are critical.
NG220AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NG220 | Basic bearing designation with 22" bore diameter | Standardized sizing for industrial applications |
| A | Angular contact design with 30° contact angle | Optimized for combined radial and axial loads |
| R0 | Open design without seals | Maximum speed capability and custom lubrication options |
NG220AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: The NG220AR0 utilizes chrome steel rings and balls with a brass cage, providing excellent strength and wear resistance under heavy loads. This material combination ensures reliable performance in demanding industrial environments.
Enhanced Load Capacity: With a radial dynamic load rating of 14,290 lbf and axial static load rating of 37,712 lbf, this bearing excels in applications requiring substantial load support. The 30° contact angle effectively distributes stress across the bearing surfaces.
Corrosion Protection: The Endura-kote chromium plating offers superior corrosion resistance, extending service life in harsh operating conditions while maintaining dimensional stability across the operating temperature range of -30°C to 110°C.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight radial internal clearance (0.0000 – 0.0005"), this bearing ensures smooth operation and minimal vibration in precision applications.
