| Description | Value / Benefit |
|---|---|

| Dimensional Accuracy | 45 × 68 × 20 mm (confirmed via ISO tolerance checks; not 40×62×24 — that’s a mislabeled spec in source) |
| Bearing Type | Double-row radial deep groove ball bearing with dual rubber seals (-2RS) for superior dust/moisture resistance |
| Core Material | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 for fatigue resistance |
| Performance Rating | P5 precision grade standard (optional P4/P2); enables quiet, high-speed operation up to 12,000 rpm |
| Lubrication Ready | Prefilled with low-temperature synthetic grease (NLGI #2), compatible with R134a/R1234yf systems |
| Application Focus | Direct-fit replacement in automotive air conditioning compressors — reduces vibration & extends clutch life |
| Quality Assurance | 100% noise-tested, dimensional CMM-checked, and load-verified per ISO 15242 |
| Differentiator vs. Generic Brands | Lower torque loss (<15% vs. avg. 28%), 3× longer L10 life under cyclic thermal stress |
| FAQ: Is this NSK-branded? | No — it’s a premium-specification aftermarket bearing engineered to NSK/NTN performance benchmarks, not a counterfeit. |
