Double Pitch roller chains are created in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Generally these chains are comparable to ASME/ANSI conventional goods except that the pitch is double. They can be accessible in Transmission Series, Conveyor Series with Conventional (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to reasonable speeds, lower chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 to the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some providers usually do not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Conventional (small) Rollers
This series is often made use of on light to moderate load material handling conveyors with or without the need of attachment links. 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 on the next greater chain size. The chain amount is uncovered by including 2000 to your ASME/ANSI chain number and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on a conveyor track lowering friction. Chain numbers are located during the exact same way as noted above except the last digit over the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Generally sprockets really should be generated specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Conventional (small) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may be used supplied the number of teeth is 30 or more.
