ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Usually these chains are comparable to ASME/ANSI typical solutions except the pitch is double. They can be offered in Transmission Series, Conveyor Series with Conventional (smaller) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, reduced chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 towards the ASME/ANSI chain quantity as well as prefi x letter ?¡ãA?¡À. Note that some organizations 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 etc.
Conveyor Series with Normal (modest) Rollers
This series is often used on light to reasonable load materials managing conveyors with or without attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. website link plates on the upcoming more substantial chain dimension. The chain variety is discovered by incorporating 2000 for the ASME/ANSI chain number and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess significant rollers so that the chain rolls on a conveyor track reducing friction. Chain numbers are found from the identical way as noted above except the final digit about the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
Generally sprockets should be generated specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four standards nonetheless, for Transmission Series and Conveyor Series with Common (modest) Rollers, ASME/ANSI B29.one Typical roller chain sprockets may be utilised offered the quantity of teeth is thirty or additional.
