Import 304 Stainless Steel Cylinder Rod — Buy in Bulk from Supplier in China

The 304 stainless steel cylinder rod from Fenghua Lingong Pneumatic Componenets Factory is available in diameters from 6 millimetres to 1200 millimetres and lengths from 200 millimetres to 10,000 millimetres, manufactured from austenitic 304 stainless steel with surface finish options to match precise engineering requirements. This rod serves as the extension element in pneumatic and hydraulic cylinders, transmitting force through linear motion while resisting corrosion from atmospheric moisture and process contaminants.

The diameter range spans precision instrument rods at the small end through heavy-duty hydraulic rams at 1200 millimetres, with 304 stainless steel providing typical yield strength of 205 MPa and tensile strength of 520 MPa in the annealed condition. Surface finish selection affects seal friction, wear rate, and corrosion initiation; common options include turned (Ra 3.2-6.3 micrometres), ground (Ra 0.4-1.6 micrometres), and polished (Ra 0.1-0.4 micrometres). The chromium oxide passive layer that provides corrosion resistance can be compromised by surface defects, making finish specification critical for rod longevity in reciprocating applications.

Primary applications include pneumatic cylinder piston rods, linear motion guide shafts, valve stems, and structural tie rods in food processing, pharmaceutical manufacturing, marine hardware, and chemical processing equipment. The 10,000 millimetre maximum length suggests continuous casting or hot rolling followed by cold drawing and centreless grinding capabilities at the factory. Buyers must confirm diameter tolerance class (h6, h7, h9, or f7 depending on seal type and bearing fit), straightness over the ordered length, and whether the surface is passivated after final machining to restore the corrosion-resistant oxide layer.

Fenghua Lingong Pneumatic Componenets Factory maintains its registered address at No.2 Chengxin Road, Jishan Industrial Zone, Xikou, Fenghua, Ningbo 317200, Zhejiang Province, China. The supplier carries a harbour trust tier designation with zero recorded response rate and zero average response hours, indicating no platform-mediated communication history is available for evaluation.

The company profile does not disclose establishment year, factory floor area, employee count, annual production capacity, revenue figures, named customers, or ISO quality management certification. Ningbo and the surrounding Fenghua district host numerous small-to-medium metalworking enterprises serving the Yangtze River Delta manufacturing cluster. Prospective buyers should conduct independent verification of business registration, production capability, and quality system status through direct factory audit or third-party inspection before reliance on any claimed manufacturing credentials.
