Product Details
Why Choose Our High-Precision Cylindrical Roller Bearings?
| Description | Key Value |
|---|---|
| Precision Grades | P0, P6, P5, P4, P2 — ultra-tight tolerances for high-speed & low-vibration applications |
| Brand Compatibility | Fully interchangeable with SKF, Timken, NTN, NSK, KOYO, NACHI — same dimensions & performance |
| Load Capacity | Optimized radial load support; NJ-type handles axial + radial, NU-type for pure radial loads |
| Material & Hardness | GCR15 bearing steel (62–64 HRC), vacuum-degassed for fatigue resistance |
| Design Type | Separable, open-type cylindrical roller design — easy mounting, maintenance & replacement |
| Size Range | Outer diameters: 35–400 mm; e.g., 17×40×16 mm (NJ419EM equivalent) |
| Applications | Wind turbines, gearboxes, machine tools, rolling mills, pumps & industrial motors |
| Quality Assurance | ISO 9001 certified production; 100% dimensional & noise testing; traceable batch codes |
| Differentiator vs. Generic Brands | Superior roller profile grinding, tighter raceway surface roughness (Ra ≤ 0.2 μm), and optimized internal clearance |
| FAQ: Can these replace SKF NJ419EM? | Yes — identical ABEC/ISO standards, interchangeability verified per DIN 620 & ISO 15 |
Engineered for reliability under extreme speed and load — our bearings deliver longer service life, lower friction, and quieter operation than standard alternatives.
