Product Details
Key Features & Technical Highlights
| Description | Core Selling Point |
|---|---|
| Self-aligning double-row ball bearing (Model 2303) | Automatic heart adjustment compensates for shaft misalignment up to ±2.5° — extends service life by 40% vs. standard radial bearings |
| 95×170×32 mm metric dimensions, high-precision P0–P2 grades | Drop-in replacement for SKF 2303 series — fully interchangeable with identical load ratings and tolerances |
| Bearing steel (GCr15) + steel/brass cage | Superior fatigue resistance & noise control — tested to ISO 15242-2 vibration Class A |
| C0/C3/C4 clearance options | Optimized thermal expansion handling — ideal for variable-temp industrial gearboxes & pumps |
| 60° contact angle + radial load capacity | Handles combined radial + moderate axial loads — no need for auxiliary thrust bearings |
| OEM/ODM support + BDL trademark (China origin) | Factory-direct pricing — 25% lower than branded equivalents, backed by 12-month warranty |
| Carton/pallet packaging, 10–15 days delivery | Stocked in EU/US warehouses — express shipping available upon request |
| HS Code 8482101000 — compliant for global customs | Hassle-free import documentation included with every order |
| Production capacity: 1,000,000 pcs/year | Scalable supply for distributors & OEMs — MOQ as low as 50 pcs |
| ISO/TS 16949 certified manufacturing | Full traceability: batch logs, hardness reports, and dimensional Cpk ≥1.33 on all lots |
Engineered for demanding applications: agricultural machinery, textile looms, HVAC blowers, and mining conveyor idlers. Unlike generic imports, our 2303 features micro-ground raceways and optimized internal geometry — reducing friction heat by 18% (tested per DIN 5415). FAQ: Can it replace SKF 2303? Yes — identical ABEC-1/P0 specs and mounting dimensions. Is lubrication pre-filled? Standard version is grease-ready (Lithium complex, NLGI #2); custom greasing available. What’s the max speed? 3,200 rpm (with C3 clearance & proper housing fit). Ready to request a sample or bulk quote? Contact us now — our engineers reply within 2 hours.
