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 standards. Generally these chains are very similar to ASME/ANSI normal products except that the pitch is double. They are really available in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to reasonable speeds, very low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 towards the ASME/ANSI chain variety along with the prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Conventional (tiny) Rollers
This series is often used on light to reasonable load material handling conveyors with or without the need of attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. website link plates in the next bigger chain dimension. The chain variety is located by incorporating 2000 on the ASME/ANSI chain variety and also the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess big rollers so that the chain rolls on the conveyor track reducing friction. Chain numbers are identified while in the identical way as mentioned over except that the final digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Generally sprockets really should be produced specially for these chains according on the ASME/ANSI B29.three and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Regular (little) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets may perhaps be used offered the quantity of teeth is thirty or much more.
