Double Pitch roller chains are made in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are equivalent to ASME/ANSI standard merchandise except the pitch is double. They are out there in Transmission Series, Conveyor Series with Regular (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, lower chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to your ASME/ANSI chain number as well as the prefi x letter ?¡ãA?¡À. Note that some businesses will not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (tiny) Rollers
This series is often employed on light to moderate load materials handling conveyors with or with no 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. hyperlink plates from the upcoming more substantial chain dimension. The chain variety is observed by including 2000 to your ASME/ANSI chain number plus the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess substantial rollers so that the chain rolls on a conveyor track minimizing friction. Chain numbers are identified from the identical way as mentioned above except the final digit about the chain variety is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
On the whole sprockets ought to be created specially for these chains according for the ASME/ANSI B29.three and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.one Standard roller chain sprockets could be applied provided the amount of teeth is 30 or much more.
