New easier to fit propeller shaft bearing for abrasive waters
Thordon Bearings, a world leader in grease and oil-free bearing solutions has announced the introduction of Composite EF®, a newly-designed water lubricated bearing offering all the benefits of the proven long-lasting Thordon Composite bearing now with the ease of installation of a bronze- backed rubber bearing.
Composite EF® is supplied in a single 3:1 L/D length with finished inside diameter to standard shaft sizes from 152 to 305mm (6 to 12in.)and overbuild on the outside diameter to accommodate variations in housing sizes. One-seventh the weight of metallic bearings, two persons can easily handle and fit the largest Composite EF® size eliminating the need for heavy rigging.
Specially formulated to provide superior wear life in very abrasive water conditions such as inland river systems, Thordon Composite EF® bearings operating in combination with hard coated nickel-chrome-boron sleeves routinely outwear rubber propeller shaft bearings by a factor of two or more. With over 15 years experience on hundreds of push boats operating on America's muddy Mississippi River system confirm real-life bearing wear rates of 0.075-0.100mm(0.003-0.004in.) in 6,000-7,000h of annual use.
