MagSealed® Body Construction

The MagSealed principle is based on a special magnetic oil, which has been developed by the NASA to transport fuel to the starships based on the magnetic principle. Such an oil for reel production is not available in the super market. It has to be manufactured under most difficult circumstances. The embedded ferric oxide, which is necessary for the magnetic field has a diameter of 1/100.000mm and is that small, that the surface of a single particle has the tenth of the size of an influenza virus.
The molecules in this new "metal oil" are capable of changing. If they are exposed to a magnetic field, they change their shape and the oil forms a fluid seal. This magnetic oil is that strong, that it would stick to a magnetic bucket, even if the bottom was cut out.
Such a seal, based on the principle of liquid magnetic oil produces nearly no friction, isolates perfectly and prevents even penetrating of little dust particles. The big challenge for the DAIWA engineers was the development of a reel, which is designed for the principle of the magnetic oil to generate a kind of liquid membrane, that prevents water penetration. The MagSeal design is based on the purpose to keep water away from a spinning reel. First of all for sea anglers this is an amazing idea - since it promises a longer life span. No corrosion, better function. If salt water penetrates the reel and dries, it crystallizes, corrodes the gearing and affects the ball bearings.
The simplest solution for implementing a sealed mechanism, would have been the usage of a rubber seal. But this would cause such a strong friction, that an isolation of the rotor and axis would have been impossible. Only the use of a metallic oil in combination with a magnet provides the desired isolation effect without heavy friction. Years of research and development were required to develop such a reel isolation.
We call this liquid isolation MagSealed.
FUNCTIONALITY
To prevent the penetration of water, dust particles or salt crystals between rotor and reel body, we have developed a nearly frictionless barrier based on magnetic oil, which cannot be overcome by neither water nor smallest particles. The result is a silky-smooth running.

MagSealed® Line Roller
The smoother a line roller turns, the less friction emerges between line and roller. If delicate salt or dirt particles penetrate the line roller, it is continuously dragged and the friction is considerably increased.
The magnetic MagSealed oil forms a barrier, which prevents the intrusion of water and therefore also of salt and dirt particles into the line roller, which could affect the free rotation.

MagSealed® Ball Bearings
Our DAIWA technology further on changes the fishing tackle market. Our engineers succeeded in further devolving the Mag Sealed invention to a new level. First we sealed the axis, then the line roller and now the ball bearing!
MagSealed is a new chapter in the history of the fishing reel. Thanks to our targeted research and development, we succeeded in integrating MagSealed into a ball bearing. For a long lifespan and a silky-smooth running over a long period. A revolution!
