Description
High Precision Mechanical Bearing N224EM NJ224EM Cylindrical Roller Bearing
| Description | Key Specification |
|---|---|
| Precision & Grade | P0–P2 ultra-precision rating (ABEC-1 to ABEC-9 equivalent), ideal for high-speed, low-vibration applications |
| Load Capacity | Radial-only, high-load cylindrical design with optimized roller-cage geometry |
| Dimensions (mm) | 120 × 215 × 40 — compact yet robust for space-constrained OEM machinery |
| Material & Hardness | GCR15 bearing steel, hardened to HRC 60–64, vacuum-degassed for fatigue resistance |
| Sealing & Lubrication | Open type — compatible with oil, grease, or dry-film lubricants per operational demand |
| Separability | Fully separated design (NUP224EM) — simplifies mounting, maintenance & axial location |
| Application Scope | Wind turbines, gearboxes, industrial pumps, CNC spindles, and heavy-duty conveyors |
| Quality Assurance | ISO 9001 certified production; 100% dimensional & noise testing; traceable batch records |
| SKF-Compatible Advantage | Exact interchange with SKF N224EM/NJ224EM — same load ratings, tolerances & mounting interfaces |
| FAQ: Why choose this over generic brands? | Superior roller profile grinding, tighter raceway roundness (<0.8μm), and lower vibration (Z2V2 level) ensure longer service life vs. standard P0 imports |
