NG250AR0 Bearing Product Overview & Core Advantages
The NG250AR0 is a single row angular contact ball bearing engineered for precision applications requiring high load capacity and dimensional stability. Featuring inch-series dimensions with a large 25" bore, this bearing is specifically designed to handle combined radial and axial loads simultaneously. Its 30° contact angle provides optimal load distribution, while the Endura-kote chromium plating offers superior corrosion resistance and extended service life in demanding environments. Manufactured to ABEC-1 precision standards, this bearing delivers reliable performance in applications where accuracy and durability are critical.

|---|---|
| NG250 | Basic bearing designation with 25" bore diameter |
| A | Angular contact design with 30° contact angle |
| R0 | Open construction (no seals or shields) |
NG250AR0 Bearing Structural Features & Performance Benefits
Enhanced Load Capacity: The single row angular contact design with 30° contact angle enables the bearing to support substantial combined loads, including significant axial loads in one direction. With a radial dynamic load rating of 15,239 lbf and axial static load rating of 40,920 lbf, this bearing delivers exceptional performance under demanding conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and OD tolerance: -0.0018" to 0"), ensuring consistent performance and easy installation. The radial internal clearance of 0.0000-0.0005" provides optimal running characteristics for precision applications.
Durable Construction: Features chrome steel rings and balls with brass cage for reliable operation. The Endura-kote chromium plating provides excellent corrosion resistance, extending service life in challenging environments while maintaining ROHS compliance.
Thermal Performance: Operating temperature range of -30°C to 110°C with pre-lubrication ensures stable performance across various environmental conditions.
