Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are related to ASME/ANSI regular merchandise except that the pitch is double. They may be out there in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, lower chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 for the ASME/ANSI chain amount and the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Standard (smaller) Rollers
This series is often utilized on light to moderate load material managing conveyors with or without the need of attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates with the subsequent greater chain dimension. The chain variety is uncovered by incorporating 2000 on the ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains 
possess substantial rollers so that the chain rolls on the conveyor track cutting down friction. Chain numbers are found in the very same way as mentioned above except that the final digit on the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Usually sprockets needs to be developed specially for these chains according on the ASME/ANSI B29.three and B29.four standards having said that, for Transmission Series and Conveyor Series with Regular (compact) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets might be employed presented the number of teeth is 30 or much more.
