Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are related to ASME/ANSI standard solutions except the pitch is double. They’re accessible in Transmission Series, Conveyor Series with Typical (little) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, minimal chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to your ASME/ANSI chain quantity and the prefi x letter ?¡ãA?¡À. Note that some organizations do not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Normal (little) Rollers
This series is usually utilised on light to moderate load material managing conveyors with or devoid of attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series hyperlink plates (i.e. website link plates with the upcoming bigger chain size. The chain variety is uncovered by including 2000 to your ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À. 
Conveyor Series with Substantial (oversized) Rollers
These chains possess substantial rollers in order that the chain rolls on the conveyor track decreasing friction. Chain numbers are identified inside the same way as noted above except the final digit to the chain amount is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Generally sprockets need to be made specially for these chains in accordance to your ASME/ANSI B29.three and B29.four specifications on the other hand, for Transmission Series and Conveyor Series with Normal (smaller) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets may well be made use of provided the quantity of teeth is 30 or additional.
