The 14 sizes of standard roller chains are available ranging from 25 to 240 which includes these in conformity with ANSI (American National Regular Institute), and ISO (Global Organization for Standardization).
The chains not only meet the prerequisites to the minimum tensile strength prescribed by ANSI and ISO, nevertheless they also offer the best class good quality during the world like a higher fatigue power
Appropriate employs
?Standard use for driving and lifting gear.
Examples
?Driving transfer units and other gear. For multilevel parking.
Selection of chains
For selection of a chain, see the tables of “Max. Horsepower Ratings” for typical roller chains and “Designing of Chain Transmission”. Nevertheless, only to get 
a particular situation of lower speed and much less shock, “Low-speed selection” process could also be referred to.
Typical roller chains as much as five strands can be found. The conventional system for Y YD YS Series three-Phase asynchronous Motors connecting pins and plates is rivet style (RP).
The cotter sort (CP) is available for conventional chains and HK chains of 80 or more substantial.
Sprockets
The common roller chains is usually engaged with standard sprockets from the corresponding nominal numbers. For sprockets, refer to your table of “Dimensions” for every dimension of chain.
Connecting back links and offset backlinks
For connecting back links and offset hyperlinks, refer for the table of “Dimensions” for every size of chain.
The connecting hyperlinks are typically R or C connecting backlinks during which the pins are clearance-fitted together with the connecting plate. Considering that clearance-fitted links are inferior for the base chain in Max. allowable tension as during the situation of one-pitch offset backlinks (OJ), “Low-speed selection” cannot be referred to. Because the Max. kilowatt ratings are made the decision looking at the power of connecting backlinks and OJ, the clearance-fitted connecting back links and OJ may be utilized if your chains are picked according on the “General selection”. When a increased Max. allowable tension is needed for the connecting hyperlink, utilize the interference-fitted connecting website link (H connecting link) of the HI-PWR-S chain, and in the situation of offset links, use 2POJ.
