ND075AR0 Bearing Product Overview & Core Advantages
The ND075AR0 is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. Manufactured to ABEC-1 precision class, this bearing is designed to accommodate combined radial and axial loads simultaneously, with a 30° contact angle optimizing its thrust load capacity. Its Endura-kote chromium plating provides superior corrosion resistance, making it ideal for demanding environments. The compact design, with a 7.5" bore and 0.5" width, offers a high load capacity in a thin-section profile, delivering outstanding rigidity and operational stability.

|---|---|
| ND075 | Bearing series designation with 7.5" bore diameter |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
ND075AR0 Bearing Structural Features & Performance Benefits
High Precision Construction: Built to ABEC-1 tolerance standards with precise bearing dimensions (7.5" bore, 8.5" OD) ensuring consistent performance in precision assemblies.
Superior Load Capacity: The single row angular contact design with 30° contact angle enables handling of significant combined radial and axial loads (2536 lbf dynamic radial, 6250 lbf static axial).
Advanced Material Selection: Chrome steel rings and balls paired with a brass cage provide excellent durability and smooth operation under high-speed conditions.
Corrosion Resistance: Endura-kote chromium plating offers enhanced protection against corrosion, extending service life in harsh operating environments.
Optimized Internal Clearance: Controlled radial internal clearance (0.0000 – 0.0005") ensures precise operation and minimal vibration.
