ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Generally these chains are similar to ASME/ANSI conventional goods except the pitch is double. They are obtainable in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to moderate speeds, reduced chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 towards the ASME/ANSI chain variety as well as prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Conventional (small) Rollers
This series is often utilized on light to reasonable load material 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 more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates on the following greater chain size. The chain quantity is identified by adding 2000 towards the ASME/ANSI chain number along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess significant rollers to ensure that the chain rolls on a conveyor track cutting down friction. Chain numbers are identified while in the similar way as noted over except the last digit within the chain amount is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
On the whole sprockets should be produced specially for these chains in accordance towards the ASME/ANSI B29.three and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may perhaps be utilized offered the number of teeth is 30 or extra.
