Certified Chrome Shaft Supplier for ISO 9227 NSS Resistance

Certified Chrome Shaft Supplier for ISO 9227 NSS Resistance

Looking for a reliable chrome shaft supplier? Our certified chrome shafts offer exceptional quality and durability with key specifications that meet stringent industry standards. Our products feature precise external diameter accuracy, available in f7 and f8 tolerances, and are manufactured with a surface roughness of up to Ra0.2μm. We ensure superior performance with a hard chrome thickness of at least 15 μm for diameters less than Φ22.225mm, and 20 μm for diameters greater than Φ24mm.

Our chrome shafts boast a minimum surface hardness of HV 850, ensuring resilience and long-lasting functionality. For straightness, our products meet the requirement of max 0.25/1000mm for diameters less than Φ20mm, and max 0.2/1000mm for larger diameters. Roundness tolerance is precisely controlled at 1/2 of the specified tolerance.

Available in standard lengths from 3M to 6M and sizes ranging from Φ6 to Φ255 (Φ1/4” to Φ10”), our chrome shafts also offer excellent corrosion resistance. Tested to ISO 9227 NSS standards, our shafts achieve R9 ratings of 72 hours for diameters less than 20mm and 120 hours for larger diameters. We perform these tests in our own laboratory to ensure compliance with industry standards.

Our chrome shafts are available in various steel grades, including JIS S45C, SAE1045, DIN CK45, EN C45E, and ASTM 1045. We can also supply special specifications and materials upon request. Choose us for high-quality chrome shafts that meet your exact needs and industry standards.

If you're searching for high-quality hard chrome shaft solutions, look no further. Our chrome shaft products are engineered to meet the highest standards of precision and durability. We offer chrome shafts with exceptional external diameter accuracy in f7 and f8 tolerances, ensuring a perfect fit for your needs. The surface roughness of our shafts is meticulously controlled, with a maximum Ra of 0.2μm, guaranteeing a smooth finish.

Our hard chrome shafts feature a robust hard chrome thickness of at least 15 μm for diameters less than Φ22.225mm and 20 μm for diameters equal to or greater than Φ24mm. This thickness is crucial for enhancing the shaft's durability and wear resistance. With a minimum surface hardness of HV 850, our shafts offer superior performance and longevity under demanding conditions.

Straightness is another key attribute of our products. For shafts with diameters less than Φ20mm, the maximum allowable deviation is 0.25/1000mm, while for larger diameters, it is 0.2/1000mm. Our shafts are also manufactured to strict roundness tolerances, which are half of the specified tolerance, ensuring high concentricity.

Available in standard lengths ranging from 3M to 6M and sizes from Φ6 to Φ255 (Φ1/4” to Φ10”), our chrome shafts are designed to meet diverse application requirements. They offer excellent corrosion resistance, tested to ISO 9227 NSS standards, achieving R9 ratings of 72 hours for diameters less than 20mm and 120 hours for larger sizes.

Our testing capabilities include NSS and CASS tests performed in our own laboratory, ensuring each shaft meets rigorous quality standards. We offer a variety of steel grades, including JIS S45C, SAE1045, DIN CK45, EN C45E, ASTM 1045, and 20MnV6, with special specifications and materials available upon request. Trust us for your hard chrome shaft needs and experience unmatched quality and performance
