The 14 sizes of standard roller chains are available ranging from 25 to 240 including those in conformity with ANSI (American Nationwide Standard Institute), and ISO (International Organization for Standardization).
The chains not merely meet the requirements for the minimum tensile strength prescribed by ANSI and ISO, but they also provide the prime class quality while in the globe such as a high fatigue strength
Suitable uses
?Common use for driving and lifting tools.
Examples
?Driving transfer units as well as other equipment. For multilevel parking.
Variety of chains
For variety of a chain, see the tables of “Max. Horsepower Ratings” for normal roller chains and “Designing of Chain Transmission”. Even so, only for any particular situation of minimal velocity and less shock, “Low-speed selection” approach can also be referred to.
Regular roller chains up to five strands are available. The typical approach for GW Variety No-jam dredge pump connecting pins and plates 
is rivet form (RP).
The cotter form (CP) is obtainable for conventional chains and HK chains of 80 or bigger.
Sprockets
The regular roller chains is often engaged with typical sprockets of your corresponding nominal numbers. For sprockets, refer towards the table of “Dimensions” for each dimension of chain.
Connecting back links and offset hyperlinks
For connecting backlinks and offset back links, refer to the table of “Dimensions” for every dimension of chain.
The connecting hyperlinks are typically R or C connecting hyperlinks during which the pins are clearance-fitted with the connecting plate. Since clearance-fitted links are inferior to your base chain in Max. allowable tension as in the case of one-pitch offset hyperlinks (OJ), “Low-speed selection” can’t be referred to. Since the Max. kilowatt ratings are made a decision thinking about the power of connecting backlinks and OJ, the clearance-fitted connecting backlinks and OJ could be applied in case the chains are chosen in accordance to your “General selection”. Whenever a larger Max. allowable tension is required to the connecting website link, use the interference-fitted connecting hyperlink (H connecting link) of a HI-PWR-S chain, and within the case of offset back links, use 2POJ.
