085 (1/2") hub sprockets

085 hub sprockets work with 085 roller chain of 1/2" (12.7 mm) pitch, described in DIN 8187 / ISO 606. 085 chain has the same pitch as 08B, but a different roller and inner width, so it needs sprockets with their own tooth profile.

085 hub sprockets - correct meshing and even wear

A sprocket matched to 085 chain ensures correct meshing and even wear - replacing it with a sprocket of a different type quickly destroys the chain. You bore out the pilot bore for your shaft, and C45 steel ensures durability.

How to recognise 085 chain - customer questions about hub sprockets

How do I know the machine runs 085 chain?

The designation is usually stamped on the chain plates. If it is not visible, measure the roller diameter and inner width - the 12.7 mm pitch alone is not enough, because 08B, 081 and 083/084 chains have it too.
