The U Groove Ball Bearing SR188 ZZ is a miniature deep‑groove bearing designed for yo‑yo and high‑speed hobby applications. It has a bore of 6.35 mm, an outer diameter of 12.7 mm and a width of 4.762 mm, and each unit weighs 0.25 kg. The bearing is supplied in GCR 15 chrome steel or stainless‑steel variants and incorporates dual metal shields (ZZ) for contamination protection. The product listing notes ISO 9001 certification, confirming a consistent quality‑management process.
In the miniature bearing market, GCR 15 chrome steel is the standard material for achieving the hardness required for high‑speed rotation, while stainless‑steel versions are chosen for corrosion‑resistant environments. Typical ABAB‑type bearings of this size fall within ABEC 1‑3 tolerance classes and meet ISO tolerance class P5. The SR188’s dimensions place it within the common envelope for hobby‑grade rotating components, making it interchangeable with other manufacturers’ SR188‑type units.
Primary users include yo‑yo manufacturers, precision instrument makers and hobbyist motorised product developers who import the bearing in bulk. Buyers should confirm the minimum order quantity, lead‑time and preferred Incoterm - many Chinese bearing exporters operate on FOB Shanghai terms with payment by T/T. Because the listing does not disclose exact pricing or MOQ, interested importers are advised to request a formal quotation and verify the supplier’s shipping capabilities before placing an order.

Before placing an order, verify the exact bore, outer diameter and width against your design drawings, and confirm the material grade (chrome steel or stainless steel) matches the operating environment. Request the ISO 9001 certificate and any test reports that demonstrate compliance with the stated dimensions and tolerances. Also check that the supplier’s harbour trust tier aligns with your risk assessment criteria.
Logistics for Chinese bearing suppliers typically involve FOB terms from a port such as Shanghai or Tianjin, with lead times ranging from a few weeks to a month depending on order size. Payment is commonly made by telegraphic transfer (T/T) after a pro‑forma invoice, but the exact terms should be agreed in writing before shipment. Confirm the incoterm and any freight forwarder arrangements to avoid unexpected costs.
Quality assurance should include a pre‑shipment inspection of bore size, outer diameter, width and shield integrity, using calibrated gauges. Request a third‑party inspection report or arrange for an in‑house audit if possible. Ensure the shipment is accompanied by a packing list, material safety data sheet and the ISO 9001 certificate to satisfy import compliance requirements.
