Description
Key Specifications & Benefits of NUP2222EM Cylindrical Roller Bearing
| Description | Core Value |
|---|---|
| High-Precision P0–P2 Tolerance Grades | Ensures ultra-low vibration & extended service life in high-speed machinery |
| Bearing Steel (GCr15) Material | Superior hardness, fatigue resistance & dimensional stability under heavy radial loads |
| Single-Row, Separated Design | Easy mounting/dismounting — ideal for OEM maintenance & tight-space applications |
| Radial Load Capacity Only | Optimized for pure radial force transmission — no axial misalignment risk |
| Open Seals + Oil/Grease/Dry Lubrication | Flexible maintenance integration across industrial, automotive & energy sectors |
| 110 mm Bore × 200 mm OD × 53 mm Width | Precise fit for standard shaft/housing tolerances (per ISO 15:2011) |
| Non-Aligning (Rigid) Structure | Maximizes rigidity and positioning accuracy in CNC spindles & gearboxes |
| Multi-Brand Compatibility (NTN/NSK/Koyo/Timken) | Drop-in replacement with verified interchangeability & global technical support |
| 100,000 pcs/month Production Capacity | Guaranteed supply continuity — no lead-time delays for bulk orders |
| Made in China (ISO 9001 Certified Factories) | Rigorous 100% dimensional & noise testing — meets SKF ABEC-5 equivalent standards |
Engineered for demanding applications: wind turbine gearboxes, mining conveyor drives, steel mill roll stands, and precision machine tool spindles. Unlike generic imports, our NUP2222EM features tighter raceway surface roughness (<0.2 μm Ra), optimized roller profiling, and strict cage concentricity control — reducing friction by up to 18% versus standard P0 grade.
FAQ: Q: Is this bearing suitable for high-speed operation? A: Yes — rated up to 4,200 rpm (oil-lubricated, light load). Q: Can it handle axial loads? A: No — use NU/NUP series only for radial + limited axial (NUP has fixed flange). Q: What’s the max operating temperature? A: 120°C continuous (with lithium complex grease).
