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. Generally these chains are related to ASME/ANSI conventional merchandise except that the pitch is double. They are obtainable in Transmission Series, Conveyor Series with Typical (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to reasonable speeds, very low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 on the ASME/ANSI chain quantity along with 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 possibly be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Regular (compact) Rollers
This series is often used on light to moderate load materials dealing with conveyors with or without having attachment back links. 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. hyperlink plates in the upcoming bigger chain size. The chain amount is uncovered by including 2000 for the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess massive rollers so that the chain rolls on the conveyor track decreasing friction. Chain numbers are identified during the exact same way as mentioned above except the final digit around the chain amount is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Usually sprockets should be created specially for these chains in accordance to the ASME/ANSI B29.three and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.one Standard roller chain sprockets may be utilized provided the quantity of teeth is thirty or extra.
