A marine engine running at 4,500 rpm for 4 hours will spin its propeller shaft through the strut bearings over a million times. Vesconite Hilube is the advanced polymer that's the perfect long-lasting bearing material for this high-wear application.
Vesconite Hilube is internally lubricated. Even in dirty or silty water, the material provides superior low-friction performance with an exceptionally long wear life—more than 10 times that of bronze. And unlike nylon or rubber, it won't soften or swell.
Due to its dimensional stability and high load strength, it doesn't squeak like some polymers. This is as important for quiet trolling as it is for towing a skier or motorsailing. And because the propeller shaft runs smoothly within the bearing, it doesn't vibrate or suffer from stick-slip.
The potential for shaft, log or strut damage due to low-quality bearings is high. For the custom or OEM builder, it's hard to beat Vesconite Hilube. The advanced polymer offers a full range of benefits that provide economical, trouble-free results and years of service.
Vesconite Hilube is offered as machined parts, or as stock shapes that are easily machined to +/-0.001". Hollow bar, solid rod and plate shapes are available in a wide array of dimensions and thicknesses.
