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 standards. Generally these chains are equivalent to ASME/ANSI typical products except that the pitch is double. They’re offered in Transmission Series, Conveyor Series with Normal (compact) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually used 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 variety is obtained by incorporating 2000 to your ASME/ANSI chain variety along with the prefi x letter ?¡ãA?¡À. Note that some firms will 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 on.
Conveyor Series with Typical (compact) Rollers
This series is usually applied on light to moderate load materials dealing with conveyors with or without attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates of the subsequent greater chain dimension. The chain amount is identified by incorporating 2000 towards the ASME/ANSI chain quantity as well as prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess substantial rollers so that the chain rolls on the conveyor track cutting down friction. Chain numbers are observed in the same way as mentioned over except that the last digit around the chain quantity is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Normally sprockets ought to be created specially for these chains in accordance on the ASME/ANSI B29.3 and B29.4 specifications nonetheless, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets might be utilized provided the number of teeth is thirty or extra.
