The 14 sizes of normal roller chains can be found ranging from 25 to 240 such as those in conformity with ANSI (American National Regular Institute), and ISO (Worldwide Organization for Standardization).
The chains not simply meet the specifications for the minimum tensile power prescribed by ANSI and ISO, however they also provide the top class excellent within the world which includes a high fatigue power
Suitable uses
?MSR CLASS BUSHED ROLLER STEEL CHAIN Standard use for driving and lifting equipment.
Examples
?Driving transfer units and also other tools. For multilevel parking.
Variety of chains
For choice of a chain, see the tables of “Max. Horsepower Ratings” for common roller chains and “Designing of Chain Transmission”. Even so, only for any distinctive case of very low pace and much less shock, “Low-speed selection” strategy can also be referred to.
Conventional roller chains as much as five strands can be found. The conventional technique for connecting pins and plates is rivet type (RP).
The cotter form (CP) is available for common chains and HK chains of 80 or greater.
Sprockets
The standard roller chains may be engaged with normal sprockets of the corresponding nominal numbers. For sprockets, refer for the table of “Dimensions” for each size of chain.
Connecting back links and offset hyperlinks
For connecting back links and offset links, refer to your table of “Dimensions” for each dimension of chain.
The connecting hyperlinks are generally R or C connecting hyperlinks by which the pins are clearance-fitted using the connecting plate. Considering that clearance-fitted back 
links are inferior to the base chain in Max. allowable tension as inside the situation of one-pitch offset back links (OJ), “Low-speed selection” can’t be referred to. Since the Max. kilowatt ratings are determined considering the strength of connecting backlinks and OJ, the clearance-fitted connecting backlinks and OJ might be used if the chains are selected according to the “General selection”. Whenever a increased Max. allowable tension is required for that connecting website link, use the interference-fitted connecting link (H connecting link) of the HI-PWR-S chain, and inside the situation of offset backlinks, use 2POJ.
