ND160AR0 Bearing Product Overview & Core Advantages
The ND160AR0 is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. Featuring a substantial 16-inch bore and constructed with Endura-kote plating, this bearing is designed to handle significant combined loads, including substantial radial and axial forces. Its optimized 30° contact angle provides superior axial load capacity and high rigidity, making it an ideal solution for demanding industrial environments where precision and durability are paramount.
ND160AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ND160 | Bearing series designation with 16-inch bore diameter |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
ND160AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row design with 30° contact angle provides optimal stress distribution, enabling the bearing to handle substantial combined loads with a radial dynamic load rating of 3856 lbf and axial static load capacity of 10130 lbf.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore tolerance: -0.0018"– 0"), ensuring consistent performance in precision applications.
Enhanced Durability: Constructed with chrome steel rings and balls combined with brass cage for superior strength and wear resistance. The Endura-kote chromium plating provides excellent corrosion resistance and extended service life.
Optimized Design: Features precise shoulder diameters (inner: 16.37", outer small-side: 16.63", outer large-side: 16.718") for proper mounting and load distribution, contributing to the bearing's high static load moment of 37620 lbf.
