Product Details
Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning double-row ball bearing (Model 2221M) | Automatic misalignment compensation up to ±2.5° — extends service life & reduces maintenance |
| 95×170×32 mm metric dimensions | Precise OEM replacement for SKF 2221M, ISO 281 compliant |
| P0–P2 precision grades available | Ultra-low vibration & noise — ideal for high-speed industrial drives |
| C0/C3/C4 radial clearance options | Optimized preload control for thermal expansion & load conditions |
| High-carbon chromium bearing steel (GCr15) | Hardness HRC 60–64; fatigue-resistant per ISO 683-17 |
| Steel or brass cage | Brass cage option ensures smooth operation in high-temp/lubrication-limited environments |
| Radial load capacity: 128 kN (Cr) | Handles heavy-duty applications including conveyor pulleys and gearboxes |
| Made in China — BDL brand, HS Code 8482101000 | ISO 9001-certified production; 1M units/year capacity with full traceability |
| OEM/ODM support + custom packaging (carton/pallet) | Faster lead time (10–15 days) vs. global SKF lead times — no MOQ for sample orders |
| 60° contact angle design | Enhanced axial load handling — outperforms standard deep-groove bearings in combined-load scenarios |
Engineered for demanding applications: mining conveyors, paper mills, wind turbine yaw systems, and agricultural machinery. Backed by 100% dimensional & performance testing — every batch certified.
Why choose this over generic alternatives? Unlike budget clones, our 2221M features micro-polished raceways, strict ΔDmp/Δdmp tolerance control (<0.008 mm), and real-time hardness mapping — verified via third-party lab reports.
FAQ: Q: Is it interchangeable with SKF 2221M? A: Yes — identical ABEC/P0 tolerances and mounting dimensions. Q: Can it replace 22216 or 22218? A: No — those are larger bore sizes; confirm shaft diameter first. Q: What’s the max operating temperature? A: 120°C continuous (with lithium-complex grease).
