If you are reading this, the chances are that whatever type of vessel you have has noise and / or vibration issues. Welcome to the solution; in the form of Bruntons new SigmaDrive units.

Many products exist which attempt to solve the problem of good propeller shaft alignment with varying degrees of success. They may use rubber couplings, carden units or thrust bearings but, our new 21st Century solution is, we believe, the only way to solve the problem. It uses special constant velocity joints… and yes, there are cv solutions already available, but our cv joints are able to resist the propeller thrust without the need for thrust bearings. They are extremely compact and able to transmit higher torque than other couplings with similar dimensions.

Manufactured from a special bronze alloy, SigmaDrives are a premium product requiring virtually no maintenance and containing no bearings or rubber in their construction. In addition to requiring little maintenance themselves, fitting one also means considerably reduced maintenance will be necessary on other stern gear components.

SigmaDrive anti-noise and vibration solutions are available for virtually every type of craft with engines up to 1300hp, and beyond that output custom built units can be produced. Here are the units principal benefits.

• Dramatically reduces, and may eliminate entirely, noise and vibration generated by a vessels propshaft/s.

• Compact size, comparable to a standard shaft coupling.

• Provides perfect alignment for the propeller shaft and works perfectly in line or out.

• Easy and quick to fit, usually without slipping the vessel and without the need to modify the propeller shaft, or fit fixture plates or brackets for thrust bearings that are no longer required.

• Contains no rubber or bearings, and is manufactured from a special alloy that ensures long life with little maintenance requirement.

• A highly cost effective solution requiring little or no costly modifications to the vessel.
