ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are comparable to ASME/ANSI standard merchandise except the pitch is double. They are really out there in Transmission Series, Conveyor Series with Conventional (tiny) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to reasonable speeds, minimal chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 towards the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some companies will not 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 Conventional (small) Rollers
This series is often applied on light to reasonable load material dealing with conveyors with or without the need of attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. website link plates in the following larger chain dimension. The chain variety is observed by adding 2000 to your ASME/ANSI chain quantity as well as prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers to ensure the chain rolls on a conveyor track decreasing friction. Chain numbers are discovered inside the similar way as mentioned above except that the last digit on the chain quantity is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
In general sprockets need to be generated specially for these chains in accordance to the ASME/ANSI B29.three and B29.four standards nonetheless, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may be made use of supplied the quantity of teeth is 30 or a lot more.
