The 14 sizes of normal roller chains can be found ranging from 25 to 240 which include people in conformity with ANSI (American PRECISION ROLLER CHAIN National Standard Institute), and ISO (Global Organization for Standardization).
The chains not just meet the prerequisites to the minimum tensile strength prescribed by ANSI and ISO, nevertheless they also supply the leading class quality within the globe including a high fatigue power
Appropriate uses
?Basic use for driving and lifting products.
Examples
?Driving transfer units and other tools. For multilevel parking.
Selection of chains
For variety of 
a chain, see the tables of “Max. Horsepower Ratings” for conventional roller chains and “Designing of Chain Transmission”. Nonetheless, only for a special situation of reduced speed and significantly less shock, “Low-speed selection” method also can be referred to.
Typical roller chains as much as 5 strands can be found. The regular strategy for connecting pins and plates is rivet variety (RP).
The cotter style (CP) is available for conventional chains and HK chains of 80 or greater.
Sprockets
The typical roller chains can be engaged with common sprockets of your corresponding nominal numbers. For sprockets, refer to your table of “Dimensions” for every size of chain.
Connecting hyperlinks and offset hyperlinks
For connecting hyperlinks and offset hyperlinks, refer to the table of “Dimensions” for each size of chain.
The connecting back links are generally R or C connecting links by which the pins are clearance-fitted using the connecting plate. Given that clearance-fitted hyperlinks are inferior on the base chain in Max. allowable tension as during the situation of one-pitch offset hyperlinks (OJ), “Low-speed selection” cannot be referred to. Because the Max. kilowatt ratings are decided contemplating the power of connecting back links and OJ, the clearance-fitted connecting links and OJ could be utilized should the chains are chosen in accordance to your “General selection”. When a higher Max. allowable tension is required for the connecting website link, use the interference-fitted connecting hyperlink (H connecting link) of the HI-PWR-S chain, and while in the case of offset hyperlinks, use 2POJ.
