05B (8 mm) hub sprockets

05B hub sprockets work with 05B roller chain of 8 mm pitch to DIN 8187 / ISO 606. This is the smallest B series chain in our range - it combines compact design with enough strength for many light industrial drives.

05B (8 mm) hub sprockets - a small drive that tolerates dirt

A 05B drive is small and light, yet it transmits motion without slip and copes well with dirty conditions. It works well in packaging and printing machines, automation equipment, light conveyors and workshop equipment. You bore out the pilot bore for your shaft, so one sprocket can be adapted to different designs.

05B-1 and 05B-2 hub sprockets in C45 steel

05B-1 simplex and 05B-2 duplex sprockets in C45 steel with unhardened teeth - each version has its own subgroup. A duplex sprocket carries a higher load at the same pitch and diameter.

Does 05B chain have an American equivalent - customer questions

Does 05B chain have an American equivalent?

There is no direct equivalent. The closest chain, ASA 25 (04A), has a 6.35 mm pitch, so it does not work with 05B sprockets.

How do I recognise 05B chain?

Measure the distance between the centres of adjacent pins - on 05B chain it is 8 mm. The designation is also sometimes stamped on the chain plates.
