ND300AR0 Bearing Product Overview & Core Advantages
The ND300AR0 is a single row angular contact ball bearing engineered for precision applications requiring high load capacity and dimensional stability. Featuring Endura-kote chromium plating, this bearing delivers superior corrosion resistance and extended service life. Its 30° contact angle is optimized to handle significant combined radial and axial loads simultaneously, making it ideal for applications demanding high rigidity and precision positioning. Manufactured to ABEC-1 tolerance class, it ensures consistent performance in demanding industrial environments.
ND300AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ND300 | Basic bearing designation with 30" bore diameter |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
ND300AR0 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The single row construction with 30° contact angle provides exceptional radial dynamic load rating of 5397 lbf and axial static load capacity of 15260 lbf, enabling reliable operation under combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore diameter tolerance: -0.0030"– 0"), ensuring precise fit and optimal performance in precision applications.
Enhanced Durability: Features Endura-kote chromium plating on all components for superior corrosion resistance and reduced friction. The brass cage material provides excellent stability and guidance for the chrome steel balls.
Thermal Performance: Operating temperature range of -30°C to 110°C with pre-lubrication ensures consistent performance across various environmental conditions.
