General Trading of Special Products and Standard Products as per customers request

As a part of serving our valued clients, we have extended our activities to providing them with the products that they need. This become our outsourcing services to clients. With this activity, we have established some products that are not common to other suppliers or rarely difficult to find. Thus we included it in our business line. Below is the outline of these products, and on the next pages you can find short references.

THE CUTLESS BEARINGS

Cutless bearings refer to rubber lined bearings operating with water lubrication on an elasto-hydrodynamic principle. The fluted design of the bearing utilises basis lubrication principles to allow formation of hydrodynamic water wedges at the bearing surfaces by flow of water from the grooves.

Cutless bearings have a wide spectrum of marine applications, which include propeller shaft bearings in sterntubes or struts, rudder bearings and cutter bearings, in a variety of craft. Besides marine applications, cutless bearings are also used in hydroelectric turbines, centrifugal pumps and other water submersible devices.

When used in propeller shaft housing, the cutless bearing provides a structural support with built-in resilience that allows the bearing to yield in sympathy with the bending of the boats structure and thus prevents shaft bearing misalignment or shaft wear. The bearing also reduces vibration and the volume of noise being transmitted into the boat. It also absorbs shock and has an advantage of being almost maintenance free.

THE BABBITT BEARINGS

In 1839, Isaac Babbitt patented a formula for a bearing metal made out of 89.3% tin, 7.1% antimony and 3.6% copper. This alloy has great anti-friction qualities and is still utilized even these days. Tin is expensive, so other cheaper grades that contain lead, antimony or zinc were formulated that were good enough for situations requiring less strength.
