ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Usually these chains are very similar to ASME/ANSI regular solutions except that the pitch is double. They are really obtainable in Transmission Series, Conveyor Series with Conventional (modest) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to moderate speeds, low chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to the ASME/ANSI chain variety plus the prefi x letter ?¡ãA?¡À. Note that some organizations tend not to use a prefi x letter for this series so the chains may well be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Regular (smaller) Rollers
This series is often utilized on light to moderate load material managing conveyors with or with out 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 hyperlink plates (i.e. hyperlink plates on the upcoming larger chain size. The chain amount is located by incorporating 2000 towards the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess significant rollers so that the chain rolls on the conveyor track lowering friction. Chain numbers are discovered within the exact same way as noted above except the last digit to the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Generally sprockets needs to be created specially for these chains in accordance towards the ASME/ANSI B29.three and B29.four requirements nevertheless, for Transmission Series and Conveyor Series with Common (tiny) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may well be employed supplied the number of teeth is thirty or a lot more.
