COUNTROSE BEARINGS

Bearings for Water Lubricated Applications

Marine Bearings  -  Pump Bearings 

Countrose Bearings is a division of Tufnol Composites Ltd specialising in the manufacture of rubber lined bearings for use with water lubrication.  These are used all over the world for rudder and propeller shaft bearings in small to medium sized boats, including fishing vessels and other workboats and for leisure craft.  A special range of bearings is also manufactured for use in water pumps.

COUNTROSE Marine Bearings

Countrose Water Lubricated Bearings are ideal for use in a marine environment. 

They have a special synthetic rubber liner with moulded internal grooves or ‘flutes’ which are designed to optimise the performance of the water lubricant.  In normal operation, the rotation of the shaft creates a water layer between shaft and bearing, giving extremely low friction and reducing wear.

The special internal shape of Countrose bearings is designed to maintain this 'hydrodynamic' lubrication even at low speeds, and high loads.  The flow of water also helps to keep the bearing cool.

Over the last 25 years, Countrose Bearings have established a reputation for durability and excellence.  They are approved by Lloyds and Countrose manufacturing systems are quality controlled to high ISO 9001:2000 standards.

All Countrose Marine Bearings are precision ground in the bore using a special technique, to ensure a high degree of accuracy, concentricity and finish.

PRODUCT RANGE

Countrose Marine Bearings in the standard range are moulded with a specially formulated polyurethane material and are available with either brass or phenolic (non-metallic) outer shells.

The polyurethane compound used by Countrose is a very tough, highly abrasion resistant material with properties which allow it to operate at loads beyond that of other rubbers. Its high resilience and abrasion resistance makes it ideally suited to the toughest working environments.  Polyurethane is slightly absorbent and, when immersed in water, it will expand a small amount, until equilibrium is reached. Countrose Bearings are designed for shaft diameters to ISO g8 tolerances and the bearings are ready made with initial clearances to cater for the dimensional movements caused by changes in temperature and water content.

In addition to the standard range, a wide range of sizes can also be made to special order.  Bearings with special shell materials or nitrile rubber liners can also produced.
