ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are comparable to ASME/ANSI standard goods except that the pitch is double. They may be accessible in Transmission Series, Conveyor Series with Typical (little) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to moderate speeds, lower chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 for the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some providers 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 on.
Conveyor Series with Standard (tiny) Rollers
This series is often utilized on light to reasonable load material dealing with conveyors with or with out 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 of the upcoming larger chain size. The chain amount is uncovered by incorporating 2000 to the ASME/ANSI chain quantity and also the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess significant rollers to ensure that the chain rolls on a conveyor track cutting down friction. Chain numbers are located from the very same way as mentioned over except the last digit about the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
On the whole sprockets really should be developed specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 specifications even so, for Transmission Series and Conveyor Series with Common (small) Rollers, ASME/ANSI B29.one Common roller chain sprockets may perhaps be used offered the quantity of teeth is thirty or much more.
