ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are comparable to ASME/ANSI common items except that the pitch is double. They're readily available in Transmission Series, Conveyor Series with Standard (tiny) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to reasonable speeds, very low chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 on the ASME/ANSI chain quantity 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 may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Regular (modest) Rollers
This series is often used on light to reasonable load materials handling conveyors with or devoid of attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates with the up coming more substantial chain size. The chain quantity is uncovered by including 2000 to your ASME/ANSI chain amount plus the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess substantial rollers so that the chain rolls on a conveyor track lowering friction. Chain numbers are uncovered inside the exact same way as noted above except the last digit within the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
On the whole sprockets ought to be created specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four requirements however, for Transmission Series and Conveyor Series with Regular (little) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets may well be made use of provided the amount of teeth is thirty or additional.
