Equipment designers often focus only on chain pitch and overall size when selecting conveyor chains, while ignoring the importance of extended pin machining accuracy. In actual on-site use, most assembly failures and unsmooth operation are related to pin straightness and tolerance deviation.
These short pitch stainless steel chains with extended pins are mainly applied in food processing, pharmaceutical machinery and chemical conveying scenarios. The extended pin structure allows various tooling plates and auxiliary accessories to be installed directly on the chain, which simplifies the overall conveyor structure and improves assembly efficiency.
Different working environments require different stainless steel grades. 304 stainless steel is more common for regular cleaning and humid working conditions, offering stable anti-rust performance for daily production. For environments containing weak acid, chemical liquid or salt vapor, 316 stainless steel performs better in resisting pitting and chemical corrosion.
Pin processing is the core part of customized chains. Uneven pin length or slight bending will cause continuous friction during chain movement, leading to vibration, noise and even early wear. In our production process, each extended pin is processed with unified tolerance, and straightness inspection is carried out after finishing.
Custom pin extension size depends entirely on the customer's fixture height and installation space. We adjust pin protrusion strictly according to provided drawings, avoiding installation gaps or assembly interference. Confirming operating load, running speed and on-site environment before production can effectively improve chain matching accuracy and service stability.
