Import 628/8-2z, 629-2rsh — Buy in Bulk from Supplier in China

The 628/8-2Z and 629-2RSH are single-row deep groove ball bearings with sealed designs for industrial machinery. The 628/8-2Z features a single shield on one side, while the 629-2RSH has contact seals on both sides to retain lubricant and exclude contaminants. Both models use industrial-grade steel for the rings and balls, providing resistance to wear under radial and axial loads typical of electric motors and conveyor systems.

These bearings conform to standard deep groove geometry, with inner and outer ring raceways designed to support high radial loads and moderate axial loads in both directions. The 2Z suffix denotes a non-contact metal shield, and the 2RSH suffix indicates rubber seals on both sides, offering improved protection in dusty or wet environments. Typical cages for this series are pressed steel or polyamide, standard for miniature and small-sized bearings in this class.

Common applications include electric motors, pumps, agricultural machinery and small mechanical assemblies where compact size and reliable rotation are critical. Buyers source these bearings for OEM equipment and maintenance, often specifying them by bore diameter, outer diameter and width. Trade terms for this supplier require confirmation of MOQ, lead time and incoterms, as these are not fixed in the listing.

One (Tianjin) Technology Ltd. operates from the New Industrial Park in Huanyuan, Tianjin, China, specialising in sealed deep groove ball bearings for industrial and mechanical applications. The company’s profile indicates it is an imported-tier supplier with a harbor trust tier, meaning it meets baseline verification standards for export readiness but has not yet established a response rate or average reply time on the platform.

The supplier’s listing focuses on miniature and small bearings, with the 628 and 629 series representing standard deep groove designs for light to moderate loads. No additional certifications, client references, or production capacity details are provided in the available data, so buyers should request these directly. The address confirms its base in Tianjin, a major industrial hub for machinery components in northern China.
