Vesconite Marine
Vesconite is ideal for many marine applications. First tested as a stern tube bearing in 1977, it is suited to both dry and immersed applications – in fact water is an excellent coolant and lubricant.
Vesconite is extensively used for rudder and stern tube bearings. Vesconite’s internal lubricants make it eminently suited to upper rudder bearing applications where there are long periods between greasing or no greasing at all, or where water lubrication cannot be ensured when operating with light ballasts.
The hundreds of vessels equipped with Vesconite during the last 40 years – ranging from pleasure boats to tankers – testify to the desirability of long-life, low-maintenance Vesconite in marine applications.

BENEFITS TO MARINE APPLICATIONS
- Vesconite does not swell or distort in water.
- Vesconite does not delaminate or distort under higher loads.
- Vesconite does not corrode.
- Vesconite does not require lubrication.
- Vesconite is resistant to oils and fuels.
- Vesconite bearings are easy to fit and remove.
- Vesconite prolongs shaft life
MATERIAL COMPARISON
Bronze has a high friction rating and requires lubrication. Vesconite is self-lubricating and has a low friction coefficient.
Elastomers lack dimensional stability and have a high thermal expansion. This is not the case with Vesconite.
Laminated and composite materials tend to absorb water and swell.
Rubber has high friction and causes stick-slip, resulting in vibration and high shaft wear
