Double Pitch roller chains are created in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are very similar to ASME/ANSI standard goods except that the pitch is double. They can be out there in Transmission Series, Conveyor Series with Conventional (tiny) 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 extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by adding 2000 to the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some providers do not 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 Regular (small) Rollers
This series is often made use of on 
light to moderate load materials dealing with conveyors with or with no attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series link plates (i.e. website link plates from the up coming larger chain size. The chain variety is uncovered by including 2000 for the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess large rollers to ensure that the chain rolls on a conveyor track reducing friction. Chain numbers are uncovered within the exact same way as mentioned above except the final digit about the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
On the whole sprockets must be generated specially for these chains according to your ASME/ANSI B29.3 and B29.four requirements even so, for Transmission Series and Conveyor Series with Conventional (small) Rollers, ASME/ANSI B29.one Normal roller chain sprockets could be employed supplied the amount of teeth is 30 or more.
