Kumera - Front-end Gearboxes

Kumera has designed and manufactured thousands of front-end gearboxes to the maritime segment over the last 50 years, historically also under the brand name Norgear.

With an extensive standard range of front-end gearboxes available we can offer a solution for most applications at competitive prices.
