从China供应商批发进口708c P4 Hq1 Angular Contact Ball Bearing — FOB条款

The 708C P4 HQ1 is a precision angular contact ball bearing with a 15° contact angle, designed for high-speed operation in CNC machine tools, spindle systems, and precision machinery. It features Gcr15 chrome steel rings paired with ceramic balls, a hybrid configuration that reduces weight while improving stiffness and thermal stability. The P4 precision class ensures tight tolerances for radial and axial load capacity, making it suitable for applications demanding minimal runout and high rotational accuracy.

Hybrid bearings like this combine the hardness and corrosion resistance of Gcr15 steel with the low density and high elastic modulus of ceramic balls, typically silicon nitride. This material pairing extends service life under high loads and speeds, with typical dynamic load ratings for this series ranging between 5.8 kN and 7.2 kN depending on the exact configuration. The universal matching design allows for paired mounting in back-to-back or face-to-face arrangements, a standard practice in spindle assemblies.

Primary buyers include OEMs in machine tool manufacturing, robotics, and aerospace, where precision and reliability are critical. The bearing is exported as a single unit or in matched sets, with packaging designed to prevent contamination and deformation during transit. For bulk orders, buyers should confirm MOQ, lead time, and Incoterms directly with the supplier, as these details are not specified in the listing.

Guangzhou Droke Transmission Machinery Co., Ltd. is based in Guangzhou, Guangdong, China, with its office located at Room 862, No. 623 West Fangcun Road, Liwan District.
