Teignbridge standard tapered couplings can be supplied to fit the output flange of any gearbox. Precision machined, they provide the best fit possible between coupling and shaft. They are precision machined, to close tolerances, to ensure concentricity and squareness of flange.
If supplied with shafting, coupling tapers are bedded to shafts at the factory to achieve a fit, using engineers blue, of 70% minimum. The fit of keys and keyways will also be inspected. When a coupling is supplied on its own, the fit to the shaft will need to be checked on site. The taper of the coupling, or shaft, should be scraped to produce a fit of 70% minimum. The key should be inspected for a correct fit in both coupling and shaft.
Clamp type shaft couplings can be supplied to fit the output flange of any gearbox. The advantage of using this type of shaft coupling is that the shaft length can be adjusted at the installation stage, giving the boat builder flexibility to make slight changes to the engine and propeller position. Teignbridge have supplied clamp type couplings for installations in excess of 400bhp.

I did not expect to gain much in terms of fuel use per mile, but the perfect balance of your prop certainly makes every mile a pleasure.
Every Mile is a Pleasure
After a week of testing, sea trials, bollard pull tests and the necessary inspections, during which the MCA delegated the whole of the certification process to RINA, Georgina of Ladram demonstrated a 23 tonnes bollard pull and a top speed of 11.5 knots, both exceeding our initial expectations. Teignbridge was fantastic to work with and I would definitely recommend them.
Exceeding Expectations with Teignbridge’s Largest Propeller
The revs are spot on and towing fine we are cut back anything between 200 and 250 revs and as much speed as we need. It’s like a different boat with no vibration whatsoever. I would just like to thank you [for] supplying exactly what we wanted nowadays it doesn’t always happen and the excellent service you provided.
It’s the Teignbridge Way
