Vesconite is extremely versatile. It out performs most plain bearing materials in unlubricated, lubricated or water lubricated applications.
Vesconite combines many of the advantages of metallic and non-metallic bearings and bushes. It has a higher design load limit than white metal (babbit), a higher fatigue strength and two to three times the wear life.
Vesconite gives up to 10 times the service life of phosphor bronze in poorly lubricated conditions.
Vesconite has negligible water absorption characteristics. Vesconite is one of the most dimensionally stable synthetic bearing materials available. Swelling which can lead to seizing is avoided with Vesconite. This is a problem experienced particularly with nylon bearings unless excessive clearances are provided, which reduces wear life.
Vesconite does not lose hardness in water like nylon. So even in water, Vesconite retains its high resistance to creep and wear. As it is not a laminated product, Vesconite does not delaminate.
Vesconite has a much lower friction that most laminates, elastomers and nylons, and in most applications a superior resistance to wear.
In rudder applications, the low static and dynamic coefficients of friction of Vesconite mean lower power requirements for the steering gear.
In addition to the low wear rate experienced by Vesconite bushes, users report greatly reduced wear rates on metal journal surfaces such as propeller shaft and shaft liners.
Vesconite is not susceptible to electrolytic corrosion.
Vesconite does not contain asbestos or other fibres. It is both easy and safe to machine on standard metalworking equipment. Vesconite bushes are straight forward to install and easily removed. Vesconite is resistant to most acids, solvents, hydrocarbons, oils and fuels.
