ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Usually these chains are related to ASME/ANSI normal products except that the pitch is double. They can be available in Transmission Series, Conveyor Series with Regular (tiny) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to reasonable speeds, lower chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 on the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some companies tend not to 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 Normal (little) Rollers
This series is usually utilized on light to reasonable load materials dealing with conveyors with or devoid of attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series hyperlink plates (i.e. website link plates from the next greater chain dimension. The chain quantity is identified by incorporating 2000 to your ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers so that the chain rolls on a conveyor track decreasing friction. Chain numbers are located within the same way as noted above except that the last digit about the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Normally sprockets ought to be made specially for these chains according towards the ASME/ANSI B29.3 and B29.four requirements nonetheless, for Transmission Series and Conveyor Series with Standard (small) Rollers, ASME/ANSI Typical roller chain sprockets may be utilised presented the amount of teeth is 30 or a lot more.
