Import Drawn Cup Needle Bearings — Buy in Bulk from Supplier in China

Changzhou Yunfan Bearing Co., Ltd supplies drawn cup needle bearings in standard series including HK, BK, F, FY, FH, MF, MFH, MFY, SCE, BCE, SCH, BCH, and SN. These bearings feature a thin-walled, deep-drawn outer cup, a cageless needle roller assembly, and a precision ground inner race. The design enables high radial load capacity in compact spaces, commonly used in automotive linkages, transmission components, and industrial gearboxes.

The outer cup is made from carbon steel, typically SAE 1020 or equivalent, hardened to 58-62 HRC for wear resistance. Needle rollers are produced from high-carbon chromium steel, with surface roughness below Ra 0.2 μm. The cage is absent, allowing maximum roller count and load distribution. Typical radial clearance is between 0.01 mm and 0.03 mm, depending on series and bore size. Bearings are supplied without seals unless specified.

These bearings are purchased by manufacturers of automotive steering systems, agricultural machinery, and hydraulic actuators. Buyers typically require ISO 9001 traceability and batch-specific dimensional reports. Trade terms are commonly FOB Shanghai or Ningbo, with payment via T/T or L/C. Minimum order quantities are flexible but vary by series; larger diameters often require minimum 500 pieces per size.

Changzhou Yunfan Bearing Co., Ltd is based in the Wujin Hi-Tech Industry Zone, Changzhou, Jiangsu Province, and specializes in the production of needle roller bearings. The supplier is classified as imported-tier and harbor-tier, indicating verified export activity and compliance with basic customs documentation. The listing does not state factory size, workforce, or years in operation.

The company produces bearings to meet international standards for load capacity and dimensional accuracy but does not claim ISO 9001 certification or third-party testing reports in the listing. Production is focused on standard series (HK, F, MF, etc.) with customization available on request. No information is provided on internal quality control procedures, material sourcing, or testing equipment.
