The maneCraft sterntube seal has been specifically designed to meet the demands of today's recreational and commercial marine industry. maneCraft benefits from the decades of experience of John Crane Marine International, a leader in the manufacture of sealing systems for marine and commercial shipping in over 100 nations. Drip-free - your bilge stays dry and clean Self-adjusting - This seal automatically compensates for wear and, unlike stuffing boxes, requires no adjustment Maintenance-free - Once installed, the seal requires no maintenance. Nevertheless, an inspection should be carried out at regular intervals! The maneCraft seal has a built-in emergency stop device and is classified by Germanischer Lloyd.maneCraft seals are easy to install. They replace old stuffing box systems. They do not need to be packed with gland packing and do not need to be readjusted. There is also no risk of the seal cutting into the shaft. The maneCraft mechanical seal replaces the stuffing box without having to replace the propeller shaft, even if there are constrictions in the shaft surface caused by the old stuffing box packing. All you need to do is carry out a regular inspection after the seal has been fitted in accordance with the installation instructions. This should be carried out in conjunction with the inspection of sea hoses, sea valves and other elements located below the waterline. To calculate the shaft revolutions, use the following calculation:nshaft = max. motor revolutions : gear ratio For higher speeds, all sets mentioned are also available as high-speed versions.

The PSS mechanical seal is a shaft seal that ensures sealing between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange with rubber bellows. The rubber bellows forms the connection between the stern tube and the carbon flange and is secured with hose clamps.
The rotor is pushed in front of the carbon flange and the rubber bellows is first pre-tensioned before the rotor is secured with screws. This preload compensates for the movements of the shaft and ensures contact between the flat surfaces. Any vibrations and angular deviations are compensated for by the larger bore of the carbon flange and the seal can move freely on the shaft. The stainless steel rotor is sealed to the shaft by two O-rings and rotates together with the shaft, preventing wear on the shaft. Information for ordering: An overview of the available dimensions can be found under "Downloads PDF". The product brochure can also be found there. Please select the shaft and stern tube diameter. Other/different sizes on request!
The SPW rope cutter is a great help in saving lives and ships. The rotation of the propeller draws loose obstacles floating in the water, such as ropes, nets, plastic and seagrass, directly into the cutting edges of the rope cutter and then cuts them immediately.
This happens before the obstacles damage the drive and/or the engine and therefore render the ship unable to maneuver. The load on the drive is minimal and is so effective that you hardly feel it. The SPW rope cutters are attached around the shaft with two halves of the propeller guard; no need to remove the propeller. The rope cutter ... is quick and easy to fit ... offers an effective design for cutting ropes, nets & seagrass, among other things ... results in low maintenance costs; only inspection during the yearly "check-up" when the ship comes out of the water. The SPW rope cutter (2-part) is available for shaft diameters of 25, 30 and 35 mm. Please select according to the shaft diameter.
The shaft seal prevents grease from escaping to the outside and water from penetrating to the inside! Please select the size based on the shaft diameter.
Regarding inquiry form and calculation: Please read the note at the end of this description! Regardless of the type of ship, we offer you the solution with the Bruntons SigmaDrive coupling. There are various products on the market, that try to solve the problem in different ways. The Bruntons SigmaDrive is the only way to eliminate disturbing noises and vibrations of the drive shaft! Special feature: Brunton's Sigma Drive is essentially different in that it is made from a special bronze alloy, no bearings or rubber parts are used and it is very low-maintenance. Instead, special constant velocity joints are used, which are able to transmit the propeller push without thrust bearings. Constant velocity joints are primarily used in mechanical engineering and as drive shafts in automotive engineering. Unlike simple cardan joints, they transmit the rotary motion uniformly. This prevents irregularities in the drive train and additional loads on the surrounding components. SigmaDrives are designed to be suitable for virtually all boats, from yachts to workboats, in fact pretty much any powered vessel with engines up to 1300 hp.Advantages: Noise and vibrations of the drive shaft can be drastically or completely reduced Compact size comparable to standard shaft couplings High performance and low maintenance Perfect alignment of the propeller shaft Simple installation, without fixing brackets or plates for thrust bearings Very cost-effective solution as little or no modifications to the vessel are requiredTo calculate, please copy and paste the following information together with your vessel and engine details into the notes section of the inquiry form: Yacht - make and model: Shaft diameter Ø: mm Engine - make and model: Engine power: hp/kw Engine speed (rpm): rpm Gear ratio: :1
The gland packing is pressed onto the shaft with the stuffing box piston, ensuring an even and continuous seal. Available in various sizes. Please select the desired width and length when ordering.

Our SPW VARISEAL stuffing box offers 3-fold safety thanks to a 3-chamber system. This 3-chamber system includes the following components:
1. Tallow band seal: The tallow band seal is pressed onto the shaft with the stuffing piston, ensuring an even and continuous seal.
2. Grease chamber: An additional grease cushion inside the
bush (supply by means of a grease accumulating bush or grease gun)
provides the shaft with excellent sliding properties. Thereby, firstly
safety is guaranteed, and, secondly, the danger of the shaft running in -
due to dry tallow bands - is minimized many times over!
3. Shaft seal: A shaft seal prevents grease from escaping to the outside and water from penetrating to the inside!
4. Including the tube and 4 heavy-duty clamps.
ATTENTION: Please state the shaft- and stern tube diameter when ordering!
The following standard sizes are available from stock (please see picture "Stopfbuchse Zusammenbau 2023 eng"):
