The Tides Marine SureSealTM and seriesOneTM Shaft Seals are drip-free, self-aligning propeller shaft seals that are OEM equipment on many well known brands and types of vessels. The SureSeal supports propeller shaft sizes ranging from 1 inch up to 8 inches and from 25 millimeters to 160 millimeters.

The Upper Rudder Bearing Standard (URB-STD) and the Upper Rudder Bearing-Low Profile (URB-LP) are both ABS and Lloyds approved, self-aligning design which accomodates up to 10 degrees of off-axis alignment between the mounting surface (rudder shelf) and the rudder stock. Tides Marine rudder bearings can be produced in custom sizes and lengths if needed

Tides Marine produces more than 150 different mast luff groove shapes (internal flat / internal round) as well as most common external track shapes. The track is UV stable, unaffected by salt water and available in seamless lengths to 64 feet. Measurements are done with our patented measuring discs which are sent out at no charge.
