ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. On the whole these chains are comparable to ASME/ANSI regular items except the pitch is double. They can be available in Transmission Series, Conveyor Series with Normal (smaller) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, lower chain loads and prolonged 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 plus the prefi x letter ?¡ãA?¡À. Note that some organizations tend not to use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (compact) Rollers
This series is often utilised on light to moderate load material managing conveyors with or without the need of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates with the next more substantial chain dimension. The chain number is identified by including 2000 to your ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on the conveyor track decreasing friction. Chain numbers are discovered while in the same way as mentioned above except that the final digit to the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Normally sprockets need to be generated specially for these chains according for the ASME/ANSI B29.3 and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Normal (small) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets might be employed presented the quantity of teeth is 30 or far more.
