The 14 sizes of regular roller chains can be found ranging from 25 to 240 like people in conformity with ANSI (American National Regular Institute), and ISO (Worldwide Organization for Standardization).
The chains not merely meet the demands for the minimum tensile power prescribed by ANSI and ISO, but they also give the best class high quality during the world including a substantial fatigue strength

?Standard use for driving and lifting gear.

Variety of chains
For selection of a chain, see the tables of “Max. Horsepower Ratings” for standard roller chains and “Designing of Chain Transmission”. Having said that, only to get a exclusive situation of reduced velocity and significantly less shock, “Low-speed selection” technique could also be referred to.
Conventional roller chains up to five strands can be found. The standard process for connecting pins and plates is rivet variety (RP).
The cotter type (CP) is accessible for common chains and HK chains of 80 or larger.
The typical roller chains can be engaged with typical sprockets with the corresponding nominal numbers. For sprockets, refer towards the table of “Dimensions” for every size of chain.
Connecting back links and offset hyperlinks
For connecting links and offset backlinks, refer to the table of “Dimensions” for every size of chain.
The connecting hyperlinks are normally R or C connecting back links in which the pins are clearance-fitted with all the connecting plate. Given that clearance-fitted backlinks are inferior to your base chain in Max. allowable stress as inside the case of one-pitch offset links (OJ), “Low-speed selection” cannot be referred to. Because the Max. kilowatt ratings are made a decision taking into consideration the strength of connecting hyperlinks and OJ, the clearance-fitted connecting hyperlinks and OJ may be employed should the chains are picked according on the “General selection”. Whenever a increased Max. allowable tension is required for your connecting link, utilize the interference-fitted connecting website link (H connecting website link) of the HI-PWR-S chain, and within the case of offset backlinks, use 2POJ.
