Import Deep Grove Ball Bearing — Buy in Bulk from Supplier in China

Deep groove ball bearings from Liaocheng Angel Auto Parts Group are manufactured in sizes ranging from 12mm to 28mm inner diameter, with matching outer diameters up to 72mm and widths from 12mm to 25mm. These bearings are designed for medium-load applications and are produced using standard industrial-grade chrome steel. The internal geometry follows ISO 15 guidelines for load distribution and contact angle optimization.

The bearings use stamped steel cages and are pre-lubricated with lithium-based grease. Typical radial clearance is C0, though C3 variants are available upon request. Surface finish on the raceways is approximately 0.3 micrometers Ra, which is acceptable for general mechanical use but not for ultra-high precision systems. The supplier does not specify heat treatment depth or hardness values in the listing.

These bearings are commonly used in small electric motors, power tools, and conveyor pulleys in light manufacturing. Buyers in the automotive repair and OEM component markets source them for replacement units. Trade is conducted under FOB Qingdao or CIF terms, with packaging in bulk cartons of 100 to 500 pieces per size. MOQ is not specified, but orders typically start at 500 pieces per size. Lead time is estimated at 20 to 30 days.
