Description
Key Specifications & Benefits of NUP221EM Cylindrical Roller Bearing
| Feature | Description |
| Ultra-Precise Spindle Support | Optimized for high-speed lathe spindles with P0–P2 precision grades (ISO) and minimal radial runout. |
| Bearing Steel Construction | Made from premium GCr15 bearing steel — hardened, ground, and fatigue-resistant for 3× longer service life. |
| Radial Load Capacity | High radial stiffness + separable design enables easy mounting & axial location — ideal for fixed-end applications. |
| Open Configuration | No seals — allows flexible lubrication (oil/grease/dry) and integration into sealed machine housings. |
| Dimensional Accuracy | Exact 105×190×36 mm (d×D×B); outer diameter range: 35–400 mm — compatible with SKD/SKF interchange standards. |
| Non-Aligning Design | Ensures rigidity and positional stability — critical for CNC turning accuracy and surface finish consistency. |
| OEM/ODM Ready | BDL-manufactured under ISO 9001; fully customizable (clearance, cages, coatings) to match SKF OEM specs. |
| Global Compliance | HS Code 8482500090; CE-certified; meets DIN/ISO 15242 and ABEC-1 to ABEC-9 equivalency. |
| China-Origin Quality Control | 100% inspected pre-shipment; batch traceability; 2-year warranty on material & workmanship. |
| Why Choose This Over Generic Brands? | Superior roller profile grinding, tighter raceway hardness uniformity (HRC 61–64), and lower vibration (Z2/V2 grade) vs. standard imports. |
