Vesconite Hilube is a thermopolymer, designed for particularly difficult operating environments. Hilube is specifically recommended for moist and underwater applications. These include the pump and marine industry, where regular maintenance is not practically feasible or cost-effective. Displaying superior wear life, especially in poorly lubricated and dirty conditions, Vesconite Hilube has been shown to offer up to ten times the life of bronze bushings.
Vesconite Hilube incorporates an internal lubricant that translates into an exceptionally low friction coefficient. Combined with excellent dimensional stability, low wear rates and a high load-bearing capacity. Hilube has a PV rating (pressure x velocity) four times that of nylon bushings.
Vesconite is available in a wide range of rods, bushings, plates, and machined custom parts.
Hilube Key Features
No Water Swell
Fully saturated, Vesconite Hilube has a negligible moisture absorption rate (0.5%). Its linear swell rate of 0.07% allows for fine clearances in the majority of applications. By way of contrast, nylons absorb moisture by as much as 9% of total mass – resulting in high swell rates and critical loss of clearance, which can lead to seizures.
