Key Specifications & Benefits of Nfactory Eedle Roller Bearings
| Description | Core Value |
|---|---|
| Ultra-compact needle roller design (e.g., K15×20×13 mm) | Maximizes load capacity in minimal radial space — ideal for tight assemblies |
| Radial-only, ringless construction (no inner/outer ring) | Reduces weight & inertia; simplifies mounting on hardened shafts or housings |
| Bearing steel (GCr15) with precision ground rollers | Ensures high hardness (HRC 60–64), wear resistance & long service life |
| P0–P2 precision grades & C0/C3/C4 clearance options | Meets diverse OEM tolerance requirements — from general to ultra-high-precision |
| Closed-type sealed design | Retains grease, excludes contaminants — extends relubrication intervals |
| Grease- or oil-lubricated compatibility | Flexible integration into existing lubrication systems (e.g., gearboxes, transmissions) |
| Widely used in automotive transmissions, industrial pumps, and agricultural machinery | Proven reliability in high-cycle, moderate-speed radial-load applications |
| Manufactured in China under strict ISO 9001 controls; 1M pcs/month capacity | Consistent quality + fast lead time (3–7 days) — no stock delays |
| BDL trademark — compliant with HS Code 8482102000 | Fully export-ready with global customs documentation support |
| OEM/ODM service available with custom packaging & branding | White-label flexibility — scale your SKF-aligned private label portfolio |
Why choose these over generic alternatives? Nfactory combines SKF-grade material specs and dimensional accuracy with cost-efficient production — without compromising fatigue life or noise performance. All batches undergo 100% dimensional inspection and dynamic load testing. Have a specific application or need technical validation?
