Qunma Bearing Co. in Dalian, China supplies deep groove ball bearings. These bearings are engineered to carry pure radial loads and axial loads in both directions. They are made from steel, providing durability and wear resistance. The product line covers a range of bore sizes to suit different machinery.
The low friction coefficient reduces energy loss and heat, extending service life. In the bearing industry, deep groove balls are classified by ISO 281 and typically use chromium steel grades such as 100CR6. Typical dimensions span bore diameters from 10 mm to 200 mm, widths up to 100 mm, and dynamic load ratings up to 500 kN. Standard lubrication options include oil or grease, and seals may be open, single or double.
Common applications include electric motors, pumps and gearboxes in automotive, aerospace and industrial machinery. Buyers such as OEMs and contract manufacturers value the reliability and efficiency of these bearings. Trade terms can include FOB or CIF, with payment by L/C or T/T, and the supplier offers packaging tailored to order size.

Before placing an order, confirm the steel grade, dimensional tolerances and the exact certification copies (ISO, SGS) that the supplier can provide. Verify that the catalogue matches the required bore, outer diameter and width for your equipment, and request a sample if possible to check fit and performance.
Discuss logistics early: clarify the expected lead time, preferred Incoterms such as FOB Dalian or CIF Shanghai, and the payment method (L/C or T/T). Because the supplier’s response rate is currently zero, ensure you obtain written confirmation of shipping schedules and any freight forwarder arrangements.
Arrange a third‑party inspection or request a factory audit report to validate material quality and dimensional accuracy. Ask for a test report covering load capacity and friction performance, and obtain the inspection certificate and packing list before shipment to streamline customs clearance.
