SummaryCixishi Chengben Bearing Co., Ltd. is identified as a China-based manufacturer/factory in Cixi, Zhejiang, specializing in ball bearings for motor, textile machinery, automotive, and industrial applications. Its stated capabilities include high-precision, low-noise, high-speed, and long-life deep-groove bearings, supported by process controls, full-process inspection, automated vibration and noise testing, manual noise testing, and appearance inspection. The supplier lists multiple bearing series and non-standard products, indicating a broad product range. It states that it provides professional bearing solutions and after-sales service, and reports exports to numerous countries. However, the provided information does not establish formal certifications, financial strength, dedicated innovation resources, customization performance, or independently verified customer cases.

Supplier typeThe supplier is described as both a manufacturer/factory and a professional bearing manufacturer, with a stated industrial address in Cixi, Zhejiang, China. Although one slice categorizes associated companies as wholesale and retail and calls the company a trading company, the manufacturer/factory classification and detailed production descriptions provide explicit evidence of manufacturing activity.

After-Sales capabilityThe supplier explicitly states that after-sales service is part of its work and presents itself as providing professional bearing solutions. However, no details are provided on service personnel, response times, warranty terms, repair processes, or service coverage.

R&D capabilityThe supplier states that it devotes effort to developing high-precision, low-noise, high-speed, and long-life bearings and has built a bearing brand. This supports product-development intent and technical positioning, but there is no evidence of patents, R&D facilities, engineering staff, new-product output, or verified technological achievements.

Production capacityThe supplier is identified as a manufacturer/factory offering numerous bearing categories and series, including deep-groove, motor, wheel hub, stainless steel, pillow block, flange, and non-standard bearings. It describes scientific and efficient production, full-process inspection, 100% inner-diameter inspection, roundness detection, automated vibration/noise testing, manual noise testing, and appearance inspection before packing, providing explicit evidence of production and quality-control capability.

Customization capabilityThe product information includes non-standard bearings and a non-standard series, which indicates that the supplier offers at least some non-standard product scope. The slices do not explicitly confirm engineering customization, drawing-based production, tooling development, minimum-order flexibility, or customer-specific technical support.

Client casesThe supplier states that its bearings are exported to a broad list of countries, and one trade record associates the company with Meera Industries Limited and a textile-machine bearing product. These are explicit market and transaction references, but they do not provide detailed project outcomes, repeat-order evidence, customer testimonials, or independently verified case studies.
