Import Bearings — Buy in wholesale FOB from Supplier in China

Wafangdian Jinrui Bearing Co., Ltd. manufactures UC series single-row mounted ball bearings from its facility in Wafangdian, Dalian City, Liaoning Province, China. The bearings use high-carbon bearing steel equivalent to GCr15 and AISI 52100, with tolerance grades from ABEC-1 to ABEC-9 and precision grades P0 through P6. Housing configurations include UCP, UCF, UCFL, UCT, UCPA, and UCHA styles with cast iron HT 180-200 housings, serving agricultural machinery, conveyor systems, and factory automation equipment.

The UC series design features a spherical outer surface on the bearing insert to self-align within the housing, accommodating shaft deflection and mounting misalignment typical in farming and material handling equipment. The single-row deep groove construction handles radial loads and moderate axial loads in both directions. Seal options include F seal configurations for contamination protection. Vibration grades Z1V1 through Z3V3 indicate increasing levels of dynamic balance and noise control, with higher grades required for precision motor applications and lower grades acceptable for general industrial machinery. Clearance groups C0 through C3 cover standard operating temperatures; C3 is typically specified for warm ambient conditions or slight interference fits.

Buyers in agricultural, industrial maintenance, and OEM sectors source these mounted units for their ease of installation and replacement compared to conventional bearing and housing assemblies. The supplier offers OEM services, drawing-based customisation, and free samples for evaluation. Model range spans UC201 through UC218 for the bearing inserts, corresponding to bore diameters from 12 mm to 90 mm. Packaging uses single box plus cartons plus pallets for export shipment. Specific minimum order quantities, confirmed lead times, and pricing are not stated in the listing and must be negotiated directly with the supplier.

Wafangdian Jinrui Bearing Co., Ltd. is located in Zhuhua Industrial Zone, Wafangdian, Dalian City, Liaoning, 116000, China.
