Double Pitch roller chains are developed in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. In general these chains are similar to ASME/ANSI regular items except the pitch is double. They are available in Transmission Series, Conveyor Series with Regular (smaller) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to reasonable speeds, very low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 on the ASME/ANSI chain variety plus the prefi x letter ?¡ãA?¡À. Note that some providers tend not to use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Common (tiny) Rollers
This series is usually applied on light to reasonable load materials handling conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series website link plates (i.e. link plates of your following more substantial chain size. The chain variety is uncovered by including 2000 towards the ASME/ANSI chain variety and also the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess substantial rollers in order that the chain rolls on the conveyor track reducing friction. Chain numbers are uncovered from the very same way as noted over except that the final digit around the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
On the whole sprockets need to be created specially for these chains according for the ASME/ANSI B29.three and B29.four standards even so, for Transmission Series and Conveyor Series with Conventional (little) Rollers, ASME/ANSI Common roller chain sprockets might be made use of provided the number of teeth is 30 or more.
