Import Bushing — Buy in wholesale FOB from Supplier in China

Shandong Sennai Intelligent Technology Co., Ltd manufactures precision bushings from bronze CuSn8, high‑carbon steel 52100 and cast iron. Their product range includes taper‑lock bushes, grounded bushes and hardened steel bushes, each designed to provide low‑friction bearing surfaces for rotating shafts in machinery, automotive and industrial equipment. The listings state that the components are supplied in export‑grade packaging and are priced per unit according to size, material and hardness, but no MOQ or lead‑time is disclosed.

In the bearing industry, typical pressure ratings for these bushings reach up to 150 bar, with bore diameters commonly between 0.5 in and 3 in. Standard hardness values are around 180 HB for the bronze CuSn8 grade and approximately 60 HRC for the 52100 steel, which are considered typical for high‑speed, low‑load applications. Dimensional tolerance is usually ±0.002 in, and the components are often finished to a machined surface to reduce wear. Buyers frequently request compliance with ISO 10844, the standard for bearing components, as part of their quality assurance process.

Typical users include equipment manufacturers, automotive part assemblers and plant maintenance teams seeking reliable shaft support. Importers should verify the exact material grade, hardness and tolerance required for their machines before finalising the order. Although the supplier does not publish lead‑time estimates, similar Chinese manufacturers generally deliver within 3‑5 weeks after order confirmation. Request a detailed quotation that outlines material, size, hardness and packaging to avoid any ambiguity.

Shandong Sennai Intelligent Technology Co., Ltd is located in Wangguan Village, Kangzhuang Town, 250000, China. The company carries a “harbor” trust tier, indicating that its business registration and bank details have been verified on the platform. Its response statistics show a 0.00 % response rate and an average response time of zero hours, so follow‑up communication may be required to obtain detailed information. The profile lists a broad range of bushings but does not provide specific certifications or audit results.

The manufacturer focuses on precision metal‑working for bearing components, offering bronze, steel and cast‑iron variants that serve automotive, machinery and equipment sectors. While the listing mentions export‑grade packaging, it does not disclose production capacity, lead‑time guarantees or any ISO certification beyond the typical industry reference. Prospective buyers should request documentation such as material test reports and compliance certificates to confirm that the products meet their engineering specifications. Communication is primarily conducted in Mandarin and English, and the supplier indicates willingness to customise dimensions and hardness on request.
