从China供应商批量进口32204 Taper Roller Wheel Bearing

The 32204 taper roller wheel bearing from Hebei Heng Tai Rui Xin Bearing Corp., Ltd. is a single-row metric taper roller bearing with bore diameter 20 mm, outer diameter 47 mm, and overall width 19.25 mm, conforming dimensionally to ISO 355 and DIN 720 for this series designation. Taper roller bearings accommodate combined radial and axial loads through angular contact between the tapered raceway and rolling elements, with the contact angle typically between 10 and 16 degrees for standard series. The 32204 designation follows the JIS/ISO nomenclature where '32' indicates the dimension series and '204' specifies the 20 mm bore, making this a light-duty to medium-duty bearing for automotive and general machinery applications.

Manufacturing of 32204 bearings typically employs through-hardened chromium alloy steel (SAE 52100 or equivalent) for rings and rollers, with a pressed steel cage or machined brass cage depending on the supplier's specification. Case carburising is not standard for this size; the through-hardening approach provides uniform hardness of approximately 58 to 64 HRC throughout the rolling contact zone. Lubrication grooves and holes are not standard on 32204 but may be available on request; typical operating clearance ranges from C2 to normal, with C3 available for higher speed or temperature differential conditions. Surface finish on raceways and roller profiles directly influences fatigue life, with typical Ra values below 0.2 micrometres on critical functional surfaces.

This bearing size finds primary application in automotive wheel hubs (light vehicles and trailers), gearbox countershafts, conveyor rollers, agricultural implements, and general industrial machinery where moderate load capacity in compact envelope dimensions is required. The 20 mm bore suits shaft diameters common in compact transmissions and powered implement drivetrains. Buyers should confirm with Hebei Heng Tai Rui Xin Bearing Corp., Ltd. the specific cage material, steel grade certification, heat treatment records, and whether the bearings are supplied pre-lubricated or dry. The supplier mentions FOB and CIF shipping options with flexible minimum order quantities, though exact figures are not stated and require direct confirmation.

Hebei Heng Tai Rui Xin Bearing Corp., Ltd. is located in Linxi City, Sunshine Park, Xingtai 054900, Hebei Province, China, a region with established bearing manufacturing infrastructure and supply chain clustering. The supplier tier is 'imported' with trust tier 'harbor', indicating basic marketplace verification without enhanced due diligence or transaction history visible on the platform. The response rate shows 0.00 % with zero average response hours, meaning no buyer interaction data is available to assess communication reliability.

The company profile does not disclose founding year, registered capital, production capacity, number of employees, annual turnover, export markets, named OEM customers, or specific quality system certifications such as ISO 9001 or IATF 16949. The source description contains placeholder and platform-generated language that buyers should disregard in favour of direct verification. For automotive or safety-critical applications, buyers must independently audit the facility, review manufacturing process controls, and confirm traceability systems for steel raw material and heat treatment batch records. No information is provided about in-house testing capabilities, metrology laboratory accreditation, or third-party inspection arrangements.
