Import Ball Cage — Buy in Bulk from Supplier in China

Runnhua Precision Industry International Co., Ltd manufactures ball cages for ball retention in bearing assemblies and linear motion systems. The company is located at No.1 Building, Miaoxia Jinyang Industry Zone, Zhangyang District, Dongguan, Guangdong, China, postal code 523631. Ball cages separate and guide rolling elements to prevent contact friction, maintain even load distribution, and extend bearing service life. The supplier indicates these components are used in automotive, manufacturing, and machinery sectors where precision and operational longevity are required.

The source description states ball cages are made from materials that withstand heavy loads and resist wear, with anti-corrosive finishes for challenging environments. Standard industry practice uses pressed steel, brass, or engineering polymers such as polyamide 66 or PEEK for ball cage construction, depending on operating temperature, speed, and chemical exposure. Precision engineering to stringent tolerances ensures optimal ball retention and reduced friction in mechanical systems. The listing mentions variety in diameters and configurations but provides no specific dimensional series or tolerance classes.

Typical applications include linear guideways, ball screw assemblies, recirculating ball bearings, and custom machinery where ball segregation is critical. Automotive suppliers and industrial equipment manufacturers represent the primary buyer segments. The listing references ISO certification and flexible MOQ options, though no certificate numbers, specific MOQ figures, or price bands are provided. Buyers should confirm material grade, dimensional range, surface finish specifications, and whether the supplier offers customised cage designs for non-standard bearing assemblies.
