Import Deep Groove Ball Bearing 6004 — Buy in Bulk from Supplier in China

The Deep groove ball bearing 6004 has an inner diameter of 20 mm, outer diameter of 42 mm, and width of 12 mm, conforming to ISO 15:2017. It is engineered for higher radial loads than the 6002 and can support moderate axial forces in both directions. The bearing is typically supplied with rubber contact seals on both sides, enhancing protection in dusty or damp environments.

Constructed from AISI 52100 high-carbon chromium steel, the races and balls undergo precision grinding to achieve surface finishes below Ra 0.10 µm. Standard clearance is CN, but the listing mentions low noise operation, suggesting possible C3 clearance or enhanced ball finish for quieter performance. Cage material is not specified but is likely stamped steel for cost efficiency or polyamide for higher-speed applications.

This bearing is widely used in small electric motors, gearboxes, pumps, and household appliances where vibration control and long service life are priorities. Buyers in the appliance manufacturing and automation sectors often specify this size. Trade terms are generally FOB or CIF from Chinese ports. Packaging is typically in polybags within cartons, with 50 to 100 pieces per box. Minimum order quantity is not disclosed and must be confirmed directly.
