I’ve spent enough time around machine shops and farm sheds to know this: bearings rarely fail at a convenient hour. Which is why buyers keep asking me about ARY BEARING from Xingtai Weizi Bearing Co., Ltd. Origin detail matters in this industry, so let’s note it up front—XIHUAN ROAD, HEXI TOWN, LINXI COUNTY, HEBEI PROVINCE, CHINA. That corridor has, frankly, become a dense supply ecosystem for metric deep-groove ball bearings, hubs, and ag-specials.
Three currents shape the market: faster customization (short-run specials), better seal performance for dusty work (ag, mining), and traceability. To be honest, price pressure never went away, but many customers say they’ll pay a bit more for stable noise grades and consistent grease fill.
| Parameter | Specification (≈, real-world use may vary) |
|---|---|
| Bore range | 10–100 mm (common sizes on-stock) |
| Material | GCr15 (100Cr6) bearing steel; cages: SPCC/PA66 |
| Heat treatment / hardness | Through-hardened; ≈ HRC 60–64 |
| Tolerance class | Normal (ISO 492) optional P6/P5 |
| Dynamic load rating (C) | ≈ 7–55 kN depending on size (per ISO 281) |
| Max speed (grease) | Up to ≈ 18,000 rpm for small bores; size-dependent |
| Seals | ZZ (shields), 2RS (NBR) with low-friction lip designs |
| Lubrication | Premium lithium complex, NLGI 2; ASTM-based life tested |
| Noise/vibration | V2/V3 options (ISO 15242 measurement) |
| Temp range | -20°C to +120°C (grease-dependent) |
Materials are incoming-inspected (chemical composition and cleanliness), rings are turned, heat-treated, ground, superfinished, then assembled in clean areas. Grease fill is metered; seals are pressed; finally noise/vibration checked per ISO 15242. Life is estimated by L10 per ISO 281 (I know, math on paper), but field life rides on seal integrity and alignment. Many buyers report 12–36 months in ag drives; conveyors can exceed that with decent lubrication discipline.
| Aspect | ARY BEARING | Generic no‑name | Premium EU/JP |
|---|---|---|---|
| Typical price | Low–mid | Lowest | High |
| Lead time | Around 2–5 weeks | Unpredictable | 1–8 weeks (stable) |
| QC traceability | Batch-level records | Limited | Full |
| Customization MOQ | Moderate | Varies | High |
| Noise grade options | V2/V3 offered | Unclear | V1–V3 selectable |
| Certifications | Typical suppliers here maintain ISO 9001; verify current docs | Often none | ISO 9001/IATF 16949 |
Common tweaks include non-standard bores, stainless rings for splash zones, special greases (food-grade, high-temp), and 2RS low-drag lips. I guess the smart move is to share your duty cycle and ambient temps; grease selection alone can swing life significantly (ASTM D3336 data helps).
Ag retrofit: A mid-size farm replaced generic 6205-2RS on a planter drive with ARY BEARING V3-grade/low-drag seals. Reported two seasons without mid-harvest swaps—less downtime, which is the whole point.
Cement conveyor: Quarry line shifted to sealed 6308-2RS with tighter runout. Vibration trends dropped ≈15% (plant data), so they pushed lubrication intervals out modestly—nothing crazy, but measurable.
Bottom line: ARY BEARING sits in that practical middle—cost-aware yet configurable. If your line needs elite precision, you know where to look; if you want reliable, quickly customized bearings with sensible QC, this brand is worth a trial lot.
