Double Pitch roller chains are made in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. On the whole these chains are very similar to ASME/ANSI typical merchandise except that the pitch is double. These are out there in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, reduced chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 for the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãA?¡À. Note that some providers will not use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Normal (modest) Rollers
This series is usually employed on light to moderate load material handling conveyors with or with out attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates of your upcoming larger chain size. The chain quantity is found by including 2000 to your ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess large rollers so that the chain rolls on a conveyor track decreasing friction. Chain numbers are found within the similar way as mentioned above except that the final digit around the chain amount is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
In general sprockets must be produced specially for these chains according to the ASME/ANSI B29.three and B29.4 requirements nevertheless, for Transmission Series and Conveyor Series with Common (modest) Rollers, ASME/ANSI B29.one Typical roller chain sprockets may be employed offered the amount of teeth is thirty or much more.
