Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Generally these chains are related to ASME/ANSI common products except the pitch is double. They are really available in Transmission Series, Conveyor Series with Standard (little) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, reduced chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 to your ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (compact) Rollers
This series is usually employed on light to reasonable load material dealing with conveyors with or without having attachment backlinks. 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. link plates with the subsequent more substantial chain dimension. The chain amount is found by incorporating 2000 on the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess big rollers to ensure the chain rolls on a conveyor track lowering friction. Chain numbers are observed inside the very same way as noted over except that the final digit to the chain amount is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Normally sprockets really should be created specially for these chains according towards the ASME/ANSI B29.three and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.one Common roller chain sprockets might be employed presented the number of teeth is thirty or far more.
