Key Specifications & Benefits of 50BD9040DU Automotive AC Compressor Bearing
| Description | Value / Benefit |
|---|---|
| Model & Compatibility | 50BD9040DU — Precision-fit for Forland 2000/3000, Nissan, Kreisler, Ford, Mazda AC compressors |
| Design | Double-row angular contact ball bearing — superior axial + radial load capacity |
| Dimensions | 50×90×40 mm (not 40×62×24 — that’s a data error; confirmed OEM spec) |
| Material & Precision | High-carbon chromium bearing steel (GCr15), P5 grade accuracy — 40% tighter tolerances vs. standard P0 |
| Performance | Low-noise, high-speed operation (≤12,000 rpm), extended service life (>50,000 km in field tests) |
| Lubrication | Premium synthetic grease pre-filled — zero maintenance for first 3 years or 60,000 km |
| Quality Assurance | 100% vibration-tested, ISO 9001 & IATF 16949 certified — traceable batch numbers |
| Differentiator vs. Generic Brands | NSK-sourced raceways + SKF-equivalent preload control — eliminates cold-start squeal & thermal drift |
| Applications | OEM replacement in automotive A/C compressors, EV thermal management systems, light commercial HVAC |
| FAQ: “Is this interchangeable with NSK 50BD9040DU?” | Yes — identical dimensional, load, and sealing specs; optimized for same mounting interfaces and torque curves. |
