ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Generally these chains are related to ASME/ANSI common products except that the pitch is double. These are accessible in Transmission Series, Conveyor Series with Regular (tiny) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, 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 amount along with the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Typical (modest) Rollers
This series is often made use of on light to reasonable load material managing 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 more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates on the next bigger chain dimension. The chain number is identified by adding 2000 for the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess big rollers to ensure the chain rolls on a conveyor track reducing friction. Chain numbers are discovered inside the exact same way as mentioned over except that the last digit within the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Normally sprockets needs to be produced specially for these chains according on the ASME/ANSI B29.three and B29.four standards however, for Transmission Series and Conveyor Series with Standard (small) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may perhaps be used supplied the quantity of teeth is thirty or much more.
