ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. In general these chains are equivalent to ASME/ANSI common goods except that the pitch is double. They are readily available in Transmission Series, Conveyor Series with Regular (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to moderate speeds, very low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some providers don’t use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (small) Rollers

Sprockets
Generally sprockets must be created specially for these chains according on the ASME/ANSI B29.3 and B29.4 requirements nevertheless, for Transmission Series and Conveyor Series with Common (little) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets could be utilised supplied the quantity of teeth is thirty or much more.
