Vesconite Bearings Component
Vesconite Hilube marine bearings
Water-lubricated Vesconite Hilube polymer bearings for stern tubes, propeller shafts, rudders and on-deck machinery.
Description
Vesconite Bearings supplies stern tube bearings, propeller bearings, rudder bearings and other on-deck bearings in Vesconite Hilube, a polymer the company describes as particularly suited to wet and marine conditions. Fresh water and saltwater act as lubricants for the material.
Key features
- Close clearances, which reduce vibration
- No swelling in water, no delamination or distortion under high loads, and no corrosion
- No lubrication needed; resistant to oils and fuels
- Easy to fit and remove; prolongs shaft life
- Dry coefficient of friction on stainless steel of 0.08 – 0.12; low squeal supports ship-quieting
Applications
Stern tube, propeller shaft and rudder bearings on vessels from yachts to commercial ships. On the 36-meter sailing yacht Miss Silver, two Hilube bearings (5¼″ OD, 4¼″ ID, 17″ long) replaced phenolic-backed rubber propeller bearings.
