Product Details
Hub Bearing 32BD45DU – High-Performance AC Compressor Bearing for Automotive OEMs
| Description | Key Spec / USP |
|---|---|
| Model Range | 32BD45DU, 35BD4820DUM6, 35BD5020DU, 35BD5220DU — cross-compatible with major OEM compressor platforms |
| Dimensions (mm) | 40 × 62 × 24 — precision-engineered for tight-fit AC compressor housings |
| Bearing Type | Double-sealed deep groove ball bearing — optimized for high-speed, low-torque compressor shafts |
| Material & Precision | High-carbon chromium steel (GCr15), P0–P2 precision grades — superior hardness & dimensional stability |
| Lubrication | Premium long-life grease or oil-ready — extended service life up to 150,000 km under OEM conditions |
| Noise & Vibration | Low-noise design (≤28 dB at 1800 rpm) — critical for EV/hybrid cabin quietness standards |
| Clearance & ABS | Custom radial clearance + optional ABS sensor integration — supports smart diagnostics & ADAS readiness |
| Quality Assurance | 100% vibration-tested, ISO 9001 & IATF 16949 certified — traceable batch control from China production line |
| OEM Fitment | Validated for Toyota, Honda, Hyundai, BYD & Geely compressors — full dimensional & torque compliance |
| Why Choose This Over Generic Brands? | BDL-branded but SKF-aligned tolerances, 3× longer fatigue life vs. standard Grade P6, and zero field recalls in 2025 EU/ASEAN audits |
FAQ: Q: Is this bearing compatible with R1234yf refrigerant systems? A: Yes — sealed design prevents refrigerant permeation. Q: Can you supply with custom ABEC/ISO tolerance labeling? A: Yes — OEM label packs available. Q: Do you offer sample testing kits? A: Yes — free 3-piece evaluation kits for qualified distributors.
