ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Usually these chains are comparable to ASME/ANSI typical solutions except that the pitch is double. They are readily available in Transmission Series, Conveyor Series with Standard (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to moderate speeds, low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 towards the ASME/ANSI chain variety and the prefi x letter ?¡ãA?¡À. Note that some providers don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Regular (tiny) Rollers
This series is often utilised on light to reasonable 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 hyperlink plates (i.e. hyperlink plates of the next greater chain dimension. The chain amount is found by adding 2000 to the ASME/ANSI chain number and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style 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 the conveyor track decreasing friction. Chain numbers are found in the similar way as noted over except the final digit on the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Usually sprockets ought to be made specially for these chains according to the ASME/ANSI B29.three and B29.four requirements even so, for Transmission Series and Conveyor Series with Typical (little) Rollers, ASME/ANSI B29.one Regular roller chain sprockets may well be used supplied the number of teeth is 30 or extra.
