ND140AR0 Bearing Product Overview & Core Advantages
The ND140AR0 is a high-performance Angular Contact Ball Bearing engineered for applications requiring superior precision and load handling. Designed with a single row configuration and a 30° contact angle, it excels at supporting combined radial and axial loads simultaneously. Featuring a thin cross-section and Endura-kote chromium plating, this bearing offers excellent corrosion resistance and is ideal for high-reliability, space-constrained assemblies. Its ABEC-1 precision class ensures consistent performance in demanding industrial environments.
ND140AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ND140 | Bearing series designation with 14" bore diameter |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
ND140AR0 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The 30° contact angle and precision-ground raceways enable the bearing to handle significant combined loads, with a radial dynamic load rating of 3582 lbf and axial static load rating of 9290 lbf.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore and OD tolerance: -0.0016" to 0"), ensuring smooth operation and minimal vibration.
Enhanced Durability: Constructed from chrome steel rings and balls with a brass cage for stable operation. The Endura-kote chromium plating provides superior corrosion resistance in harsh environments.
Thermal Performance: Suitable for temperature ranges from -30°C to 110°C, maintaining performance under varying operational conditions.
