New Rudder-Shaft Bearing From Thomson-Gordon
—Literature Available A new concept in rudder-shaft bearings, developed by Thomson-Gordon Limited of Burlington, Ontario, can reduce initial cost and increase wear life for ocean-going vessels, Great Lakes ships and smaller vessels down to 200 tons.
The Thorband rudder bearing costs less than traditional bearings and is made from Thordon XL, the bearing material that is an advanced polymer alloy with performance characteristics far superior to those of standard bearing materials. The Thorband bearing is supplied as a split sleeve, pre-machined to a standard wall thickness which ranges from 8 to 14 mm. Because of the low wear rate the bearing doesn't require the wall thickness of other bearing materials. Sizes range from 250 to 750 mm (10 to 30 inches) diameter in 50 mm (2-inch) increments. Each size of Thorband is designed to cover a range of housing diameters. The actual diameter required is achieved by cutting a section out of the circumference of the sleeve. Correct length is likewise achieved by cutting the sleeve to suit. Thorband bearings are available through an international network of marine distributors.
