The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Having said that, in response for the demands for smaller sized chains in recent years for higher technological innovation machinery such as office equipment, health-related machines and industrial robots, we supply 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power edition of 15. These substantial precision chains are manufactured underneath significant high-quality control particularly necessary for compact sizes, taking dress in resistance also into account.
Choice of chain
Refer to the “Low-speed selection”. On the other hand, the chain operation speed could be set substantially high depending on the sort of lubrication as shown while in the table beneath.
Connecting backlinks and offset backlinks
R connecting hyperlinks are utilized for tiny pitch chains. However, because their strength is reduced than that on the base chain, and because the clip is prone to come off in high speed operation, the use of connecting back links is just not advisable. Use a loop chain without the need of attaching connecting hyperlinks.
Offset backlinks can be found for chains other than 15 and 15H1, but their use just isn’t encouraged for your same explanation as stated for the R Connecting links.
Working speed and form of lubrication
15: A higher precision mini-pitch bushing chain which is smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI common chains applying curl bushings.
35: A ANSI conventional bushing chain suitable for smaller precision machines that require high power.
