Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are equivalent to ASME/ANSI conventional goods except that the pitch is double. They are obtainable in Transmission Series, Conveyor Series with Typical (compact) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to reasonable speeds, lower 
chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 towards the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Common (smaller) Rollers
This series is usually utilised on light to reasonable load materials handling conveyors with or without 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 in the upcoming larger chain size. The chain variety is found by including 2000 towards the ASME/ANSI chain variety and also the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on a conveyor track lowering friction. Chain numbers are found while in the similar way as noted over except that the last digit within the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Normally sprockets must be made specially for these chains in accordance to your ASME/ANSI B29.3 and B29.4 requirements even so, for Transmission Series and Conveyor Series with Standard (compact) Rollers, ASME/ANSI B29.one Common roller chain sprockets might be employed offered the quantity of teeth is thirty or much more.
