Boring and Keying

Arrow Engineering provides in-house machining, boring and keying services for
pilot bore and taper lock hubs from 30 mm up to 250 mm. Our experienced
engineers accurately machine the bore and cut the keyway to suit your shaft size, giving you
a ready-to-fit solution for couplings, pulleys, sprockets and other power transmission parts.

If you are buying a complete coupling with two hubs, please purchase this machining
service twice – once for each hub. When selecting your engineering option, add specific
instructions such as bore size, keyway size, tolerance and any special requirements in the
order comments box at checkout.
