The 14 sizes of normal roller chains can be found ranging from 25 to 240 which 
includes those in conformity with ANSI (American National Y YD YS Series three-Phase asynchronous Motors Regular Institute), and ISO (International Organization for Standardization).
The chains not just meet the necessities for that minimal tensile power prescribed by ANSI and ISO, nevertheless they also present the top class high quality within the world like a substantial fatigue power
Appropriate uses
?General use for driving and lifting gear.
Examples
?Driving transfer units and other equipment. For multilevel parking.
Choice of chains
For choice of a chain, see the tables of "Max. Horsepower Ratings" for conventional roller chains and "Designing of Chain Transmission". Nevertheless, only for any exclusive case of minimal pace and less shock, "Low-speed selection" strategy can also be referred to.
Common roller chains as much as five strands can be found. The regular method for connecting pins and plates is rivet sort (RP).
The cotter type (CP) is accessible for regular chains and HK chains of 80 or bigger.
Sprockets
The common roller chains could be engaged with typical sprockets of the corresponding nominal numbers. For sprockets, refer towards the table of "Dimensions" for each dimension of chain.
Connecting backlinks and offset links
For connecting links and offset backlinks, refer on the table of "Dimensions" for each size of chain.
The connecting back links are frequently R or C connecting backlinks by which the pins are clearance-fitted with the connecting plate. Because clearance-fitted links are inferior towards the base chain in Max. allowable tension as in the case of one-pitch offset backlinks (OJ), "Low-speed selection" cannot be referred to. Since the Max. kilowatt ratings are determined contemplating the strength of connecting links and OJ, the clearance-fitted connecting backlinks and OJ can be applied if your chains are chosen according for the "General selection". When a higher Max. allowable tension is needed for your connecting link, use the interference-fitted connecting link (H connecting hyperlink) of the HI-PWR-S chain, and during the situation of offset back links, use 2POJ.
