The smallest chain complying to 
ANSI is 25 of 6.35 mm pitch. Even so, in response to your demands for smaller chains in recent years for high engineering machinery this kind of as office equipment, health care machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 as being a high-power model of 15. These substantial precision chains are produced underneath significant good quality handle primarily required for smaller sizes, taking put on resistance also under consideration.
Variety of chain
Refer to your “Low-speed selection”. On the other hand, the chain operation speed is often set considerably higher based upon the sort of lubrication as shown during the table under.
Connecting back links and offset links
R connecting back links are made use of for modest pitch chains. Even so, since their strength is reduced than that of the base chain, and since the clip is likely to come off in large velocity operation, the use of connecting back links will not be encouraged. Use a loop chain without attaching connecting back links.
Offset hyperlinks are available for chains apart from 15 and 15H1, but their use just isn’t advised to the similar motive as stated for your R Connecting hyperlinks.
Working speed and form of lubrication
15: A high precision mini-pitch bushing chain that is certainly smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI typical chains employing curl bushings.
35: A ANSI regular bushing chain suitable for small precision machines that require high power.
