Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are comparable to ASME/ANSI standard goods except the pitch is double. They’re accessible in Transmission Series, Conveyor Series with Conventional (compact) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, very low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 towards the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some organizations 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 Typical (smaller) Rollers
This series is usually utilized on light to moderate load materials managing conveyors with or without the need of attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink 
plates on the upcoming larger chain dimension. The chain amount is identified by including 2000 for the ASME/ANSI chain amount and also the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers so that the chain rolls on a conveyor track lowering friction. Chain numbers are located inside the similar way as noted over except the final digit within the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
On the whole sprockets need to be made specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Normal (small) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets might be applied offered the amount of teeth is 30 or additional.
