Import Bearing — Buy in wholesale FOB from Supplier in China

This listing from Shandong Niushang Auto Parts Co., Ltd offers throwout bearings, also known as clutch release bearings, manufactured from chrome steel (GCr15) or carbon steel with heat treatment. These bearings are needle roller or ball-type designs that function as the critical interface between the stationary clutch fork and the rotating pressure plate in manual transmission vehicles. The supplier is located in Yandian Town Industrial Park, Linqing City, Shandong Province, with a listed trust tier of harbor and zero recorded response rate.

The material specification indicates chrome steel (GCr15), a standard bearing steel with 1.3-1.6% chromium content providing typical hardness of 60-65 HRC after quenching and tempering, or carbon steel subjected to heat treatment for case hardening. Needle roller configurations in throwout bearings typically employ drawn cup or solid race designs with cage-guided rollers for high radial load capacity in compact axial spaces. Ball-type alternatives use single-row deep groove or angular contact arrangements depending on the specific clutch actuation geometry and load vector. Standard heat treatment for these components involves through-hardening or surface induction hardening to achieve wear resistance against the diaphragm spring fingers of the pressure plate.

These bearings serve aftermarket replacement for commercial vehicles, passenger cars, and industrial machinery with manual transmissions. Buyers include automotive parts distributors, commercial fleet maintenance operators, and transmission rebuild shops. The product is typically supplied individually boxed for retail distribution or in bulk trays for high-volume B2B procurement. Importers should confirm with Shandong Niushang Auto Parts Co., Ltd whether the offering targets specific OEM references, aftermarket universal fitment, or particular vehicle model years, as throwout bearing dimensions vary by clutch摄入量, clutch diameter, and release fork configuration.

Shandong Niushang Auto Parts Co., Ltd is headquartered in Yandian Town Industrial Park, Linqing City, Shandong Province, with postal code 252665. The company operates from an industrial park setting in one of China's established bearing manufacturing regions, where Linqing City has developed a concentration of bearing production and component supply. The listing carries a harbor trust tier, which represents a baseline verification level on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating no historical response data is available through the platform's tracking systems.

The supplier's profile does not disclose manufacturing capacity, employee count, revenue figures, specific certifications, or established client relationships. No information is provided about ISO quality management systems, IATF 16949 automotive certification, or laboratory testing capabilities. Buyers should independently verify the supplier's production scope, whether they manufacture bearings in-house or operate as a trading company, and their quality control procedures for heat treatment and dimensional inspection. The address in an industrial park suggests potential for direct manufacturing, but this requires confirmation.
