Import Bearing — Buy in Bulk from Supplier in China

Ningbo Yongwei Group Co., Ltd lists miniature flanged radial ball bearings in inch and metric dimensions, with bore diameters starting at 0.1250 inch (3.175 mm) and ranging up to 0.3750 inch (9.525 mm) across the catalogue. Outer diameters span from 0.2500 inch (6.350 mm) to 0.8750 inch (22.225 mm), with flange diameters, width dimensions, and minimum fillet radii tabulated for each variant. The source data presents both open and double-shielded (ZZ) configurations, with flange widths and total width values differing between open and shielded versions of the same bearing number.

The bearings appear to be manufactured from standard through-hardened chrome steel (AISI 52100), the typical material for miniature ball bearings in this size range, though the supplier does not state material grade explicitly. Shielded variants carry the ZZ suffix and include sheet steel dust covers with synthetic rubber seals, a standard industry practice for contamination protection. Flanged designs allow for axial location against a housing shoulder without additional retaining hardware, a common requirement in compact instrumentation and small motor assemblies. The inch-dominant dimensioning suggests primary market applications in legacy US equipment, robotics, and medical devices where inch shafts remain prevalent.

Buyers for these bearings typically include industrial automation integrators, dental and medical equipment manufacturers, precision instrument makers, and small electric motor producers in North America and Europe. The Ningbo location offers proximity to Shanghai port for containerised export. Packaging, MOQ, and lead time are not stated in the source data and should be confirmed directly with Ningbo Yongwei Group Co., Ltd before placing an order.
