Shaft Couplings

ROSE MARINE stocks the Buck Algonquin line of transmission couplers. These couplers are cast from ductile iron and machined to SAE J755 specifications. Most of the couplers are machined with a universal bolt-hole pattern. All of our couplers are supplied with mounting hardware. We also offer custom machining for couplers in our full service machine shop click here or give us a call, we will happy to help you.

Shaft Couplings



Absorbs vibration, reduces noise. Saves Your Powertrain.

The DRIVESAVER™ provides a flexible, non-metallic barrier between your transmission and propeller shaft. This barrier reduces drive-train vibration, resulting in reduced noise to you, your crew and the water. As a result, you and your vessel are more efficient in a quieter environment

The DRIVESAVER™ effectively absorbs thrust and torque from the propeller shaft, as well as excessive shock from changing gears and high speed planing. It also helps control damage and misalignment from torsional engine movement. And, the DRIVESAVER™ keeps on working, under normal conditions, for the life of the drive-train, without any lubrication or maintenance.

Cutlass Bearings

Cutlass Bearings

ROSE MARINE stocks Duramax¨ water-lubricated rubber bearings. They are trusted by more marine industry professionals than any others. Duramax® bearings possess inherent vibration-dampening qualities and are non-polluting. Grit particles and other abrasives wash into grooves and are flushed away, protecting the shaft and prolonging bearing life. Standard bearings are kept on the shelf, ready to ship.

If need be, our full service machine shop can press out your worn out bearing form your stern tube and re-fit a new one

The different styles and sizes of cutlass bearings are too numerous to list here.  To determine what cutlass bearing you need, just gives a call or click on the link below

Intermediate Bearings

Intermediate bearings

Although ROSE MARINE is able to provide you with what intermediates bearing your application may require, split bearings are recommended for application where it is necessary to remove a cap for servicing or replacing a bearing.  This style eliminates removing pulleys and couplings from the shaft when replacement is required.  Loading range is limited to 30° below the joint.  The angular parting of the cap is provided with shims to compensate for wear and adjustments.
