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 & Durability | High-purity bearing steel (GCr15), hardened to HRC 60–64 — 3× longer life vs. standard grades |
| Noise & Speed | Optimized raceway geometry + micro-finished surfaces — <28 dB noise, rated for 12,000 rpm |
| Lubrication Flexibility | Prefilled with high-temp lithium complex grease (NLGI #2) — also oil-compatible for OEM rebuilds |
| Precision Grade | ABEC-5 (P5) standard — tight tolerances (Δdmp ≤ 8 μm) ensure smooth compressor startup |
| Quality Assurance | 100% vibration-tested (ISO 10816-3), batch traceable, ISO 9001 & IATF 16949 certified |
| Differentiator vs. Generic Brands | SKF-equivalent preload control + cage integrity — zero slippage under thermal cycling |
| Typical Applications | Automotive A/C compressors, HVAC systems, industrial refrigeration units — validated in -40°C to +120°C |
✅ Engineered for reliability where failure means costly downtime — trusted by Tier-1 auto parts suppliers.
❓ FAQ: Q: Is this interchangeable with NSK 50BD9040DU? A: Yes — identical dimensions, load ratings, and mounting interface.
Q: Can it replace older single-row designs? A: Only if the housing supports double-row geometry — contact us for retrofit verification.
Q: What’s the expected service life under normal AC duty? A: ≥80,000 km or 5 years (based on ISO 281 L10 life calculation).
