ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Generally these chains are equivalent to ASME/ANSI typical items except that the pitch is double. They are out there in Transmission Series, Conveyor Series with Normal (compact) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to moderate speeds, low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 towards the ASME/ANSI chain amount along with 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 perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (little) Rollers
This series is often made use of on light to reasonable load material handling conveyors with or with out attachment back 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. link plates of the upcoming bigger chain dimension. The chain amount is located by incorporating 2000 for the ASME/ANSI chain quantity as well as the 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 massive rollers in order that the chain rolls on the conveyor track lowering friction. Chain numbers are found within the same way as mentioned over except the final digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Normally sprockets really should be made specially for these chains according on the ASME/ANSI B29.3 and B29.4 specifications nevertheless, for Transmission Series and Conveyor Series with Common (tiny) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets could be applied offered the quantity of teeth is thirty or much more.
