Double Pitch roller chains are made in accordance with all 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’re 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 companies usually do not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Regular (little) Rollers
This series is usually made use of on light to reasonable load material dealing with 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 greater chain dimension. The chain amount is observed 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 inside the exact same way as mentioned over except the last digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Normally sprockets really should be made specially for these chains according on the ASME/ANSI B29.3 and B29.4 specifications nonetheless, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.one Standard roller chain sprockets may possibly be applied offered the quantity of teeth is thirty or a lot more.
