Rulon

Rulon® LR

Rulon® LR – Like Rulon® AR, a maroon colour material best known for its versatile design properties.

Rulon® LR is capable of operating at up to 10,000 PV for continuous non lubricated sleeve bearings. Higher values are possible
for intermittent service.

Rulon® has an almost universal chemical inertness. From chemicals encountered in commercial practice, only molten sodium and fluorine,
at elevated temperatures and pressure show any signs of attack.

Rulon® LR has compatibility with most hardened steel substrates. Mild steel is acceptable but harder running surfaces are better.

Rulon® J

Rulon® J – Dull gold in colour, it has one of the lowest coefficients of friction of most reinforced PTFE materials. Ideally suited for stop/start
applications where stick slip is a problem. The tribological properties of Rulon® J also make it suitable for wear and bearing component applications.

Rulon® J – is an all-polymeric reinforced PTFE compound that operates exceptionally well against soft mating surfaces such as 316 stainless
steel, aluminium, mild steel, brass and many other types of plastic. This special ‘shaft friendly’ material is low in friction and wear
as well as being self-lubricating.

Rulon® XL

Rulon® XL

Rulon® XL – Tan coloured material best for use against aluminium (including anodised) substrates. Rulon® XL exhibits very low wear in
comparison to other Rulon® grades.

Compatible with a wide range of mating surfaces, but not recommended for use with alkalis. A non-abrasive character enhances the
frictional performance to prevent galling of softer mating surfaces.

Rulon® XL is the best material for vacuum service.

Other advantages are that Rulon® XL combines low deformation under load with exceptionally good chemical resistance.
