The 14 sizes of typical roller chains are available ranging from 25 to 240 which include people in conformity with ANSI (American Nationwide Regular Institute), and ISO (Global Organization for Standardization).
The chains not just meet the specifications for that minimal tensile strength prescribed by ANSI and ISO, nevertheless they also present the top class high quality during the planet like a large fatigue strength

Variety of chains
For selection of a chain, see the tables of “Max. Horsepower Ratings” for conventional roller chains and “Designing of Chain Transmission”. Having said that, only for any special case of minimal speed and much less shock, “Low-speed selection” approach may also be referred to.
Common roller chains as much as 5 strands are available. The normal strategy for connecting pins and plates is rivet type (RP).
The cotter form (CP) is available for common chains and HK chains of 80 or larger.
The regular roller chains is often engaged with typical sprockets on the corresponding nominal numbers. For sprockets, refer towards the table of “Dimensions” for each size of chain.
Connecting links and offset links
For connecting back links and offset back links, refer to your table of “Dimensions” for every size of chain.
The connecting back links are generally R or C connecting links in which the pins are clearance-fitted with the connecting plate. Considering that clearance-fitted links are inferior on the base chain in Max. allowable tension as within the case of one-pitch offset hyperlinks (OJ), “Low-speed selection” cannot be referred to. Since the Max. kilowatt ratings are determined taking into consideration the strength of connecting links and OJ, the clearance-fitted connecting back links and OJ is often utilized in case the chains are picked according to your “General selection”. When a increased Max. allowable stress is required for the connecting link, use the interference-fitted connecting hyperlink (H connecting hyperlink) of the HI-PWR-S chain, and within the situation of offset back links, use 2POJ.
