Double Pitch Roller Chain


We have a full line of high quality double pitch roller chains, ranging from ANSI and ISO/DIN standards, materials, configurations and quality levels. Double pitch roller chains is often referred to as "extended pitch chain" because it has twice the pitch of a standard chain. Except for the pitch, double pitch roller chains are constructed in the same manner as single pitch chains to standards and conform to the same standard specifications in terms of dimensions. Unlike short pitch roller chains manufactured to ANSI standards, this type of chain is suitable for applications requiring less chain speed and power transmission and is commonly used in agricultural combines and implements.

For quotation or other information on double pitch roller chains, please contact us and we will be happy to help you.

Quality Assurance:
ISO9001: 2015 and GB/T24001-2016 / ISO14001: 2015.
