modification service
Catalogued stock sprockets are supplied either
taper bored or pilot bored. This pilot bore
allows a larger finished bore to standard H8
tolerances to be machined. A bore to H7
tolerance can also be supplied on request.
Keyways to imperial or metric specifications
and setscrews can also be machined. A rebore,
keyway and setscrew modification service is
available and further details can be obtained

Taper bushes
Taper bushes provide the quickest and simplest
means of securing sprockets to a range of both
imperial and metric shafts and are designed to
give maximum grip.
The taper surface to both the bush and sprocket
combine to provide a load bearing connection
by the lock action of the hardened high tensile
screws.
