Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are similar to ASME/ANSI standard solutions except that the pitch is double. They are offered in Transmission Series, Conveyor Series with Common (little) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to moderate speeds, reduced chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to your ASME/ANSI chain quantity along with the prefi x letter ?¡ãA?¡À. Note that some providers usually do not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Regular (tiny) Rollers
This series is often used on light to moderate load material handling conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series website link plates (i.e. website link plates from the subsequent greater chain dimension. The chain variety is discovered by incorporating 2000 for the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. 
Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess significant rollers in order that the chain rolls on a conveyor track lowering friction. Chain numbers are identified inside the exact same way as noted above except the last digit on the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Generally sprockets really should be created specially for these chains in accordance on the ASME/ANSI B29.three and B29.4 specifications even so, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.one Normal roller chain sprockets could be utilized presented the amount of teeth is thirty or much more.
