06B (3/8") hub sprockets

06B hub sprockets work with 06B roller chain of 3/8" (9.525 mm) pitch to DIN 8187 / ISO 606. It is a popular chain for light and medium drives - smaller and quieter than 08B, yet strong.

06B (3/8 inch) hub sprockets - bore them out for your shaft

You bore out the pilot bore exactly for your shaft, so one sprocket fits different designs. C45 steel copes well with loads and is easy to machine, and larger sprockets are also available in grey cast iron, which dampens vibration and works well as a large driven sprocket. The small pitch means smooth, quiet running even at higher speeds.

06B simplex, duplex and triplex hub sprockets in separate subgroups

06B-1 simplex, 06B-2 duplex and 06B-3 triplex sprockets - each version has its own subgroup. Sprockets with hardened teeth can be found in the Hardened hub sprockets group, and finished bore sprockets - in the Finished bore sprockets group.

06B sprocket vs ASA 35 chain - customer questions about hub sprockets

Does a 06B sprocket fit ASA 35 chain?

No. ASA 35 (06A) chain has the same pitch, but it is a rollerless bush chain with a different inner width. Sprockets for American chains can be found in the ASA sprockets group.

When should I choose a cast iron sprocket?

A cast iron sprocket works well as a large driven sprocket in moderately loaded drives - it dampens vibration and noise well. For driving sprockets with a small number of teeth, steel is better.
