Non-aligning, single-row, separated design with BDL brand and China origin.Key Specifications & Benefits of BDL 51308–51311 Thrust Ball Bearings
| Description | Core Value |
|---|---|
| Model Range: 51308 / 51309 / 51310 / 51311 | Direct OEM replacements for SKF 513xx series — seamless integration, zero redesign needed |
| Dimensions (e.g., 51311): 55×105×35 mm | Precise ISO-standard sizing ensures perfect fit in existing SKF-driven machinery |
| Material: High-carbon bearing steel | Superior hardness & fatigue resistance — 25% longer service life vs. standard carbon steel |
| Precision Grades: P0 to P2 | Ultra-tight tolerances for high-speed, low-vibration applications (Z1V1–Z3V3 certified) |
| Lubrication: Grease or oil compatible | Flexible maintenance — works with your current lubrication protocols |
| Non-aligning, single-row, thrust-only load | Optimized axial load capacity up to 125 kN (51311) — ideal for vertical pumps, crane turntables & gearboxes |
| ISO 9001:2008 certified & made in China | Rigorous QC at every stage — same reliability as premium brands, at 30–40% lower cost |
| Separated design | Easy installation & maintenance — no press-fit tools required |
| OEM/ODM support + 1M pcs/month capacity | Scalable supply for distributors & system integrators — fast lead times, no MOQ pressure |
| In stock & carton/pallet ready | Immediate dispatch — avoid production downtime waiting for SKF backorders |
Why choose BDL over alternatives? Unlike generic thrust bearings, BDL units match SKF’s dynamic load ratings and raceway geometry — verified via third-party dimensional & hardness testing. No compromise on noise, torque consistency, or thermal stability.
FAQ: Q: Are these drop-in replacements for SKF 51311? A: Yes — identical envelope dimensions, load ratings, and mounting interfaces. Q: What’s the max RPM? A: Up to 3,200 rpm (grease-lubed, P6 grade). Q: Do you provide test reports? A: Yes — material certs, CMM reports, and vibration logs upon request.
