Import Ball Bearing — Buy in wholesale FOB from Supplier in China

Rad Maple manufactures deep groove ball bearings in the 6000, 6200, and 6300 series at its factory in Cixi city, Zhejiang province, China. The bearings are produced from chrome steel GCr15 (also described as carbon chrome steel) and are available in open, ZZ, and 2RS sealing configurations. The supplier's production scope covers bore sizes from 6000 through 6010, 6200 through 6210, and 6300 through 6310, with particular strength in high-volume items 6204 and 6205 each running at approximately one million pieces per month. The factory operates 30 processing lines with an annual output capacity of 70 million pieces.

GCr15 is a standard Chinese bearing steel grade equivalent to AISI 52100, containing approximately 1.0% carbon and 1.5% chromium, which provides hardness of 60-65 HRC after heat treatment and good wear resistance for general industrial applications. The open variant permits maximum speed but requires external lubrication and protection from contamination; ZZ designates steel shields on both sides for moderate dust protection; 2RS indicates nitrile rubber seals on both sides for better moisture and particle exclusion. Typical deep groove ball bearings of this type operate at rotational speeds up to 12,000-15,000 rpm depending on size and sealing, with noise grades commonly designated Z1, Z2, or Z3 per GB/T 4604.

These bearings serve electric motors, pumps, agricultural machinery, and general industrial equipment where radial and moderate axial loads occur. Buyers include original equipment manufacturers, aftermarket distributors, and machinery maintenance operations across Asia, Europe, Africa, and the Americas. The supplier states capacity for global export but does not specify standard lead times, minimum order quantities, or incoterms in its listing. Importers should confirm packing details, whether single-box or bulk pallet, and verify that dimensional tolerances conform to ISO 492 or GB/T 307.1 for the intended application.

Rad Maple operates from Cixi city, a major bearing production cluster in Zhejiang province, China, with a factory workforce of 230 workers. The supplier holds a Harbor trust tier on the platform with a 0.00% response rate and zero recorded average response hours, indicating no recent buyer engagement through the platform messaging system. The supplier's address data consists of repeated country entries without a specific street address, limiting geographic verification beyond the Cixi city reference in its product description.

The company presents itself as a direct factory with 30 processing lines and 70 million pieces annual capacity, emphasizing high-volume production of 6204 and 6205 bearings. Its leading items catalogue focuses on smaller and mid-range bearings: 6000-6006, 6202-6206, and 6300-6305. The supplier does not disclose ISO certification status, export licence details, or quality management system accreditation in its listing.
