Double Pitch roller chains are made in accordance with 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 normal goods except the pitch is double. They can be available in Transmission Series, Conveyor Series with Common (compact) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to moderate speeds, minimal chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 towards the ASME/ANSI chain variety and the prefi x letter ?¡ãA?¡À. Note that some firms never use a prefi x letter for this series so the chains might be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Common (smaller) Rollers
This series is usually applied on light to reasonable load materials dealing with conveyors with or with no attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates with the following larger chain size. The chain quantity is uncovered by including 2000 on the ASME/ANSI chain number along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track decreasing friction. Chain numbers are observed within the exact same way as mentioned above except the last digit about the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
On the whole sprockets should be generated specially for these chains according to your ASME/ANSI B29.3 and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Common (compact) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets might be applied offered the number of teeth is 30 or extra.
