ISO double pitch conveyor chains

   

    The double pitch conveyor chain is a reliable material conveying component. These chains are manufactured in full compliance with DIN standards under strict quality control.  They feature superior fatigue resistance, great flexibility and outstanding load capacity, which can be equipped with matched accessories. Thanks to its compact structure, the chain is simple to install and maintain, making it the ideal solution for long-distance conveying systems.

Notes:

    In the model, A represents a standard double pitch conveyor chain that meets international standards, L represents a large roller type, and H represents a thickened chain plate type.

Advantages                                                                                                                                                                                               

Advantage categories	Core functional advantages	Functional Description
Transport efficiency	Long distance efficient transportation capacity	The pitch is twice as long as the standard roller chain, allowing for longer conveying distances with the same chain length and reducing intermediate transfer links in the conveying system.
	Short pitch chain speed comparison advantage	From the perspective of the operating speed of the chain itself, the rated operating speed of a double pitch chain is lower than that of a short pitch chain of the same specification; However, in terms of actual material conveying efficiency, a double pitch chain can achieve 1.5-3 times the material conveying speed through a double speed structure. At the same chain operating speed, the actual material conveying efficiency Short pitch chain speed comparison advantage.
Load and Structure	High load uniform load-bearing capacity	The extended pitch design increases the meshing contact area between the chain and sprocket, allowing the load to be more evenly distributed on the sprocket teeth, reducing single tooth stress, and stably carrying medium to heavy-duty conveying materials.
Energy consumption and cost	Low production cost and low loss cost	Extending the pitch significantly reduces the number of chain joints and sprocket usage for the same conveying distance, thereby lowering equipment procurement costs; At the same time, the number of hinges has been reduced by half, with fewer wear points and significantly reduced maintenance and replacement costs.
Stability and flexibility	Multi specification roller adaptability	Supports two core structures: large roller and small roller. The large roller is suitable for heavy-duty, long-distance, and high stability scenarios, while the small roller is suitable for light load, short distance, and vertical conveying scenarios, and can be flexibly selected according to needs.
