Vesconite Superlube

Vesconite Superlube is a bearing material with one of the lowest coefficients of friction of any bearing material available. It has a coefficient of friction lower than virgin PTFE (polytetrafluoroethylene).

Vesconite Superlube is exceptional in that coupled with this low friction are excellent load-carrying capabilities with ultra-low wear rates. We keep stock of rod, hollow bar, plate and, using our 80 CNC machines, machine to your drawings.

KEY FEATURES

Low friction

Vesconite Superlube has a friction coefficient of 0.05 to 0.08 under typical loads of 3 to 10MPa when tested dry against steel in long-term tests. The friction is lower than any other plain bearing material tested in long-term tests without external lubrication. The friction is similar to virgin PTFE, except that virgin PTFE cannot sustain a long-term test under any realistic loading as it wears away too quickly, for example when loaded to ≥ 1 MPa.

High load bearing strength

Vesconite Superlube is ideal for long-term bearing loads of up to 10MPa where an exceptional wear life is required.

Hard wearing

Vesconite Superlube is extremely hard wearing, with low wear as a function of the load and velocity.

No water swell

Vesconite Superlube exhibits negligible swell with prolonged exposure to water.
