Hale Propeller can straighten any of your running gear including rudders, struts, shafts, and stern tubes. We can also supply new-machined castings for any running gear that is beyond repair.
The Aqualube ranges of rubber-sleeved bearings are designed for marine and industrial applications. The bearings feature a specially formulated rubber and are molded into various shell materials. The rubber is an extremely tough, chemical and oil resistant nitride, which offers outstanding resistance to abrasion and wear, even in the most adverse conditions.
We stock a comprehensive range of standard brass shell bearings, with tolerances suited for American shaft and strut standards, will be stocked in shaft diameter sizes 1” through 3”. We can also quote, upon request, an expanded range of bearings including:
• Sizes for shafting up to 10” in diameter.
• Metric sizes from 20mm through 260mm.
• Flanged, non-metallic shelled, and spiral fluted bearings.
Inquiries for the above are welcomed.
Rubber and water make the perfect combination for a bearing material and a lubricant.
The natural resilience of rubber gives the bearing its shock, vibration and noise absorption properties. The shape of the Aqualube bearing is the main reason for its success. Unlike many other bearings in the market the Aqualube bearing strips are shaped in such a way that a hydrodynamic water wedge is formed between shaft and bearing, even at very low shaft speeds.
Water is the perfect lubrication medium, particularly for marine craft, because of its natural abundance, non-compressibility, cooling properties, and low coefficient of friction when between bearing strip and shaft.
The water enters the bearing through the longitudinal grooves and moves radically between the propeller shaft and the bearing face in a thin lm. Once this lm,
Or wedge, has developed the shaft does not actually come into contact with the bearing.
