ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. In general these chains are similar to ASME/ANSI normal items except that the pitch is double. They are accessible in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to reasonable speeds, very low chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 for the ASME/ANSI chain amount and also the prefi x letter ?¡ãA?¡À. Note that some firms tend not to use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (little) Rollers
This series is usually employed on light to moderate load materials managing 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 link plates (i.e. website link plates of your following bigger chain dimension. The chain quantity is identified by incorporating 2000 for the ASME/ANSI chain variety along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess significant rollers to ensure the chain rolls on a conveyor track reducing friction. Chain numbers are located during the identical way as noted above except that the final digit on the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Usually sprockets really should be created specially for these chains according to your ASME/ANSI B29.3 and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Standard (little) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets might be applied presented the number of teeth is thirty or extra.
