Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are equivalent to ASME/ANSI conventional goods except that the pitch is double. They may be offered in Transmission Series, Conveyor Series with Common (compact) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to reasonable 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 on the ASME/ANSI chain amount and also the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Conventional (smaller) Rollers
This series is usually employed on light to reasonable load materials handling conveyors with or without attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates from the upcoming larger chain size. The chain variety is found by adding 2000 for the ASME/ANSI chain variety and also the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form 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 a conveyor track minimizing friction. Chain numbers are found during the similar way as noted over except that the last digit within the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
On the whole sprockets must be made specially for these chains in accordance to your ASME/ANSI B29.3 and B29.four requirements even so, for Transmission Series and Conveyor Series with Standard (compact) Rollers, ASME/ANSI B29.one Common roller chain sprockets might be utilised offered the quantity of teeth is thirty or much more.
