Double Pitch roller chains are made in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Generally these chains are similar to ASME/ANSI conventional goods except the pitch is double. These are accessible in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, lower chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to your 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 may possibly be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Normal (modest) Rollers
This series is usually made use of on light to reasonable load material managing conveyors with or without having attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates from the upcoming more substantial chain size. The chain number is observed by adding 2000 for the ASME/ANSI chain amount and the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess huge rollers to ensure the chain rolls on a conveyor track minimizing friction. Chain numbers are discovered from the ASMEANSI%20Transmission%20Series%20Double%20Pitch%20Roller%20Chain%203same way as mentioned above except the last digit on the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Normally sprockets need to be produced specially for these chains according towards the ASME/ANSI B29.3 and B29.four specifications nonetheless, for Transmission Series and Conveyor Series with Normal (small) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may well be utilised provided the number of teeth is 30 or more.
