The smallest chain complying to ANSI is 25 of 6.35 mm pitch. On the other hand, in response to the demands for smaller chains in recent times for high technological innovation machinery this kind of as office products, medical machines and industrial robots, we give 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as being a high-power edition of 15. These large precision chains are produced underneath severe high-quality manage specially essential for little sizes, taking dress in resistance also under consideration.
Choice of chain
Refer to your “Low-speed selection”. Having said that, the chain operation speed can be set substantially high dependant upon the kind of lubrication as shown within the table beneath.
Connecting links and offset hyperlinks
R connecting links are employed for smaller pitch chains. Nevertheless, due to the fact their strength is decrease than that from the base chain, and because the clip is prone to come off in high speed operation, the usage of connecting hyperlinks is just not proposed. Use a loop chain without attaching connecting hyperlinks.
Offset hyperlinks can be found for chains besides 15 and 15H1, but their use is not really advised for your same purpose as stated to the R Connecting backlinks.
Working speed and type of lubrication
15: A high precision mini-pitch bushing chain that is smaller than a compact drive chain for standard applications, 25
25: Smallest bushing chain between ANSI standard chains making use of curl bushings.
35: A ANSI conventional bushing chain ideal for little precision machines that require high power.
