ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. On the whole these chains are similar to ASME/ANSI standard items except the pitch is double. They may be accessible in Transmission Series, Conveyor Series with Regular (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, reduced chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to your ASME/ANSI chain quantity as well as the prefi x letter ?¡ãA?¡À. Note that some firms usually do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Standard (little) Rollers
This series is usually applied on light to reasonable load materials managing conveyors with or devoid 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. hyperlink plates with the following bigger chain size. The chain number is identified by adding 2000 to the ASME/ANSI chain quantity and also the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess substantial rollers to ensure that the chain rolls on a conveyor track minimizing friction. Chain numbers are discovered while in the same way as mentioned over except that the final digit around the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Normally sprockets ought to be made specially for these chains in accordance for the ASME/ANSI B29.three and B29.4 standards nonetheless, for Transmission Series and Conveyor Series with Normal (smaller) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets may possibly be utilised supplied the amount of teeth is thirty or extra.
