Double Pitch roller chains are made in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Usually these chains are related to ASME/ANSI normal merchandise except the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Conventional (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to reasonable speeds, low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 towards the ASME/ANSI chain amount plus the prefi x letter ?¡ãA?¡À. Note that some firms tend not to use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (smaller) Rollers
This series is often used on light to moderate load material dealing with conveyors with or with no attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates of your subsequent more substantial chain dimension. The chain quantity is identified by adding 2000 to your ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style side plates use a suffi 
x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on a conveyor track minimizing friction. Chain numbers are identified from the similar way as mentioned over except that the final digit around the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
In general sprockets need to be developed specially for these chains according towards the ASME/ANSI B29.three and B29.four requirements nonetheless, for Transmission Series and Conveyor Series with Conventional (little) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be applied offered the amount of teeth is 30 or extra.
