Product Details
Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning double-row ball bearing (2310K-2RS) | Automatic heart adjustment absorbs shaft misalignment up to ±2.5° — extends service life by 40% vs standard radial bearings |
| Dimensions: 95×170×32 mm (ID×OD×W) | Direct replacement for SKF 2310 K; seamless integration in existing OEM designs |
| Precision grades: P0/P6/P5 available | Meets ISO ABEC-1 to ABEC-5 standards — ideal for high-speed industrial drives |
| Sealed with dual rubber contact seals (2RS) | IP54-rated dust/moisture protection — zero maintenance in harsh workshop environments |
| High-carbon chromium bearing steel (GCr15) | Hardness HRC 60–64 — superior fatigue resistance under dynamic radial loads |
| Steel or brass cage options | Brass cage enables >12,000 rpm operation — perfect for textile & packaging machinery |
| Radial load capacity: 68.5 kN (Cr) | Handles heavy-duty applications: conveyor pulleys, fan hubs, agricultural gearboxes |
| Origin: China (HS Code 8482101000), BDL certified | Fully traceable supply chain + 100% pre-shipment dimensional & noise testing |
| OEM/ODM support & 10–15 day lead time | Faster than SKF’s standard 4–6 week delivery — no MOQ for sample orders |
| FAQ: Can it replace SKF 2310 K? Yes — identical bore, outer diameter, width, and load ratings per ISO 15 | No re-engineering needed — full interchangeability confirmed by third-party lab report |
