Import Four Row Cylindrical Roller Bearings — Buy in Bulk from Supplier in China

Hebei Shengsailong Bearing Manufacturing Co., Ltd. supplies four‑row cylindrical roller bearings from its plant in Dongshiduan Industrial Zone, Xushui County, Baoding, Hebei, China. The bearings are engineered for high radial load capacity while maintaining a relatively compact radial footprint, which suits both heavy‑duty and space‑constrained applications. The supplier mentions that the design delivers increased load‑carrying capability with reduced axial load capacity, a common trade‑off in this bearing type.

In the bearing sector, four‑row cylindrical rollers are typical for machines that demand high radial support, such as crushers, mining conveyors and construction equipment. Standard material for these bearings is high‑carbon chromium steel, often complying with the GCr15 grade, and they are usually heat‑treated to achieve a hardness of 58‑62 HRC. Typical dimensional tolerances for outer diameters in this class are ±0.03 mm, and the recommended operating temperature range extends from - 40 °C to +120 °C.

These components are purchased by manufacturers of heavy machinery, mining plants and large‑scale construction firms that require reliable, long‑lasting bearing solutions. Shengsailong states that flexible minimum order quantities are available and that ISO and CE certifications back their quality management system. As the listing does not disclose exact lead times, payment conditions or packaging details, prospective buyers should verify those parameters directly with the supplier.
