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 Supelube is exceptional in that coupled to 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.
