Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Usually these chains are similar to ASME/ANSI regular products except the pitch is double. They are obtainable in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable speeds, lower chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 towards the ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some businesses tend not to use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Conventional (little) Rollers
This series is often applied on light to moderate load materials managing conveyors with or without having attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates in the next greater chain size. The chain number is located by adding 2000 on the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track decreasing friction. Chain numbers are observed in the similar way as mentioned above except that the final digit on the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets should be produced specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 standards on the other hand, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be utilised offered the number of teeth is thirty or far more.
