ARY BEARING – High-Precision, Low-Noise Bearings: Why Us?

Why ARY BEARING keeps popping up in buyer shortlists

After a week on the factory floors around XIHUAN ROAD, HEXI TOWN, LINXI COUNTY, Hebei Province, China, one name came up again and again in maintenance logs and purchase orders: ARY BEARING. The brand is the own label of Xingtai Weizi Bearing Co., Ltd., and—honestly—it’s making quiet, steady gains in markets where price sensitivity meets reliability. Not flashy, just practical.

ARY BEARING – High-Precision, Low-Noise Bearings: Why Us?

What’s driving demand right now

Two things: supply chain realism and uptime pressure. Buyers want dependable deep-groove and unit bearings without the six-week lead-time drama. In fact, many customers say ARY BEARING hits that “good enough plus” sweet spot—solid tolerances, consistent hardness, and predictable lifecycles—without punishing budgets. To be honest, that’s the whole game for MRO in 2025.

Core specs (typical, real-world use may vary)

Parameter Typical Value
Series 6200/6300 deep-groove ball bearings, others on request
Bore size range ≈ 10–100 mm
Material GCr15 (≈ AISI 52100) rings/balls; cage: steel / PA66; seal: NBR or FKM
Tolerance class ISO 492 P0/P6; P5 optional
Hardness HRC 60–64 (through-hardened)
Grease Lithium EP or low-noise grease; -20 to 120°C (FKM up to ≈ 180°C)
Speed rating Up to ≈ 22,000 rpm (6200 open); lower with seals

How they’re made (quick process flow)

  • Materials: vacuum-degassed GCr15, selected PA66/steel cages, NBR/FKM seals.
  • Methods: forging → turning → heat treatment (controlled atmosphere) → precision grinding → superfinishing → assembly → 100% spin and noise check.
  • Testing standards: ISO 492 (tolerances), ISO 76/281 (load & L10 life), GB/T 307.1, dimensional checks to ±0.005 mm typical on key IDs/ODs.
  • Service life: L10 computed per ISO 281; real-world MRO reports ≈ 8,000–20,000 hrs in moderate loads.
  • Industries: HVAC blowers, conveyors, agricultural equipment, e‑bikes, small motors, packaging lines.

Test snapshots (one batch, indicative): vibration ≤ 25 dB at 1,800 rpm; radial clearance CN/C3 within spec; grease bleed

Where they shine

If you’re swapping bearings in farm gear before harvest or keeping a packaging line from stalling, ARY BEARING is the “don’t overthink it” choice. Not exotic, but dependable. I’ve seen them last two full seasons on grain augers with correct sealing—surprisingly robust given the dust and misalignment abuse.

Vendor comparison (indicative)

Brand Origin Typical MOQ Lead Time Customization Certifications Price Level
ARY BEARING Hebei, China ≈ 100–500 pcs 2–4 weeks (stock items faster) Grease, seals, clearance, laser mark ISO 9001; IATF 16949 support on request Value
BigBrand A (Japan) JP Small lot OK 3–6 weeks Broad ISO/IATF widely available Premium
Global B (EU) EU Small lot OK 4–8 weeks Broad ISO/IATF widely available Premium+

Customization and support

For OEM runs, ARY BEARING can tailor cage type, clearance (C2–C4), grease fill percentage, and sealing profiles. Private labeling and corrosion-resistant coatings are doable. Documentation packs usually include material certs, RoHS/REACH statements, and PPAP levels upon request.

Mini case study

A midwestern packaging plant swapped legacy bearings for ARY BEARING 6204-2RS on 60 conveyor drives. Downtime fell ≈ 18% over six months; the maintenance lead told me, “We stopped babysitting idlers.” Mounting practice was tightened (thankfully), which helped as much as the parts.

Compliance notes

Conforms to ISO 492 tolerance classes; life ratings per ISO 281; materials aligned with AISI 52100/GCr15; RoHS/REACH statements available. Ask the factory for batch-specific certificates and any IATF 16949 documentation if you’re in automotive.
