| Material & Construction | High-carbon bearing steel (GCr15) inner/outer rings + PTFE-impregnated bronze liner — self-lubricating, no maintenance required |
| Load Capacity | Radial spherical design handles misalignment up to ±4° and heavy static/dynamic loads — ideal for harsh environments |
| Sliding Pair | Steel-on-steel with solid lubricant layer — low friction coefficient (μ ≈ 0.08–0.12), high wear resistance |
| Application Scope | Hydraulic cylinders, construction machinery, forging presses, automotive shock absorbers, water conservancy systems |
| Precision & Reliability | ABEC-1 tolerance grade, ≤0.005 mm roundness — ensures smooth operation and extended service life |
| Origin & Compliance | Manufactured in China under ISO 9001 & IATF 16949; HS Code 8482101000 — customs-ready and globally certified |
| Differentiator vs. Generic Brands | BDL’s proprietary heat treatment + surface hardening achieves 30% higher load rating and 2× fatigue life vs. standard equivalents |
| Quality Assurance | 100% dimensional inspection, torque testing, and axial/radial load validation per DIN 635-1 |
| FAQ: Can it replace SKF GE… series? | Yes — identical mounting dimensions, load ratings, and performance curves; full drop-in replacement with OEM documentation support |
