ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. In general these chains are similar to ASME/ANSI common merchandise except that the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Conventional (smaller) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, minimal chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to the ASME/ANSI chain number as well as the prefi x letter ?¡ãA?¡À. Note that some organizations tend not to use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Conventional (smaller) Rollers
This series is often employed on light to reasonable load material dealing with conveyors with or devoid of attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. link plates on the following more substantial chain dimension. The chain variety is identified by incorporating 2000 towards the ASME/ANSI chain variety and also the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess huge rollers to ensure the chain rolls on the conveyor track minimizing friction. Chain numbers are uncovered from the same way as noted over except the final digit over the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Usually sprockets must be developed specially for these chains according towards the ASME/ANSI B29.3 and B29.four requirements even so, for Transmission Series and Conveyor Series with Common (modest) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may possibly be made use of supplied the amount of teeth is thirty or far more.
