Short pitch precision roller chain conforms to l50, ASME/ANSI, DIN, JIS and other standards, mainly including A series short pitch precision roller chain. B series short pitch precision roller chain, heavy load series roller chain and other series.
Using high-quality materials and advanced processing technology, the product has the characteristics of high tensile strength and high fatigue strength. The tensile strength reaches more than 11 times the minimum tensile strength of ISO standard and the fatigue strength reaches more than 1 1s times the minimum dynamic load strength of l50 standard.
Products are widely used in engineering machinery, agricultural machinery and other felds, transmitting power for all kinds of machinery and facilities.
