Products Description
Universal precision roller chains comply with ISO, GB, DIN, ASME/ANSI and other standards. Made from high-quality materials and optimized processes, the products feature high strength, high fatigue resistance, high wear resistance, high precision, and impact resistance. Through special design and optimized processes, reinforced chains can be derived for special applications, such as heavy machinery, steel mills, oil fields, and engineering vehicles, etc.
Main product models include:
Short pitch precision roller chain series
Short pitch precision roller chain series
(Reinforced) short pitch precision roller chain series
Short pitch precision roller chain series
Type (straight plate type) short pitch precision roller chain series
Sealed chain: It has dust-proof function and can effectively lock the lubricating oil, which can improve the wear resistance of the chain and thus extend its service life.
Self-lubricating chain: Generally, oil-impregnated powder metallurgy, engineering plastics and materials containing Teflon (or graphite) are selected to make self-lubricating sleeves, so as to achieve the purpose of less or no lubrication for the chain.
Seamless sleeve chain: Cold extrusion forming technology is adopted to produce seamless sleeves with high roundness and less deformation, which can improve the wear resistance of the chain.
Strong pre-tensioning: It can improve the consistency of the chain, optimize the chain length accuracy, and thus enhance the fatigue strength of the chain.
Shot blasting treatment: Firstly, it can form compressive stress on the surface of chain parts, which can significantly improve the fatigue life of chain parts. Secondly, it can reduce the effective stress concentration coefficient on the surface of the chain plate holes and both sides, preventing the generation of micro-cracks after quenching.
Chain plate hole extrusion: By extruding the chain plate holes with steel balls, compressive stress can be generated on the inner wall of the chain plate holes, thereby improving the fatigue life of the chain plates.
Application fields
Aerospace, marine machinery, high-energy physics, agricultural machinery, construction machinery, forestry and papermaking, logistics and transportation, metallurgy and mining, cement manufacturing, food machinery, medical machinery, tobacco machinery, port machinery, petroleum machinery, etc.
