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 – 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® 641 – White in colour, it is produced from FDA compliant materials whilst possessing excellent load and wear characteristics.
The compatibility of Rulon® 641 with a wide range of mating surfaces, including Mild steel, 316 and 303 stainless steels as well as harder
materials, make it a good choice for many food and pharmaceutical bearing applications.
Rulon® 641 gives excellent continuous non-lubricated service up to 10,000 PV – higher for intermittent service. Whilst the load capacity of
Rulon® 641 is generally limited to 1000 psi at room temperature, deformation is a result of load, temperature and wall thickness.
Rulon® W2 – A black PTFE based material that has been developed for use in fresh- water applications. Rulon® W2 exhibits properties that are
enhanced when wet, demonstrates excellent wear characteristics, a low friction (one of the lowest wear rates in fresh-water) and good thermal dissipation.
Rulon® W2 is compatible with most metal substrates and soft mating surfaces. It is a good alternative to Rulon® J when superior chemical
resistance is required. However, it should not be used on very soft mating surfaces or where electrical insulation is desired.
Rulon® 123 – Glossy black non-abrasive compound for softer mating surfaces, such as stainless steel. FDA, USDA and NSF compliant,
this material has excellent chemical resistance. It is less expensive than Rulon® J, but is slightly less flexible and higher in wear.
Rulon® 123 releases black wear debris over time and should not be used in ultra-dry, vacuum applications, or where electrical insulation is required.
It has a high deformation resistance, good thermal and electrostatic dissipation and a low coefficient of friction. Rulon® 123 has a
maximum operating temperature of 300deg C (550deg F)
Rulon® 488 – Dull turquoise in colour and originally developed for use with painted surfaces. It has been used in veneer dryer bearings
in the plywood industry.
It has a higher load capacity than Rulon® J and better abrasion resistance than both Rulon® J and Rulon® 123.
Rulon® 488 exhibits excellent wear resistance, especially in extremely dry environments making it a material of choice in hydrogen and
natural gas compressors. An almost universal chemical resistance enables it to withstand corrosives and acids sometimes present in trace
amounts in these environments.
Rulon® 957 – Speckled green in colour, this material was developed specifically for noise dampening and abrasion resistance,
such as in commercial or residential clothes dryers.
Rulon® 957 provides low friction operation on softer mating surfaces at higher loads than Rulon® J.
Excellent performance is achieved on coated metals, particularly porcelain. Other benefits are an overall reduction in the weight of
the finished product, cost reduction due to rapid manufacturing methods and vibration absorption.
Chemical resistance is similar to Rulon® J. If you require specific information regarding Rulon® 957, please forward your technical
requirements to firstname.lastname@example.org
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.
Rulon® F – Green in colour, this grade has superior abrasion resistance with excellent insulating properties.
Rulon® F provides excellent wear resistance, especially in dry conditions. This material suitably slides against a wide range of mating
surfaces but is not recommended for contact with strong bases or steam.
Used in a wide range of wear component and bearing applications, Rulon® F is currently used as the liner in one of the composite
journal bearing range (Rulon® FCJ).
Rulon® 142 – Specially formulated linear bearing material exhibiting low wear, high thermal dissipation and good dimensional stability.
Dull blue-green in colour, Rulon® 142 has excellent mechanical properties and is the material for machine tool applications.
Low deformation characteristics limit the amount of misalignment that can occur with other bearing materials.
Strong acids and bases should be avoided when using Rulon® 142 as they may affect the fillers. If you require specific information
regarding Rulon® 142 and its chemical resistance, please forward your technical requirements to
Among the many benefits when using Rulon® 142 are the virtual elimination of stick-slip, vibration dampening, self lubrication, long life,
uniform friction, ease of application and design diversity.
Rulon® 945 – Black PTFE-based material exhibiting very low wear and deformation under load, making it ideally suited for demanding thermal
applications. Rulon® 945 actually has the lowest deformation of all Rulon® grades. In addition, it also possesses excellent chemical resistance
and good dimensional stability.
It is not suitable for applications requiring electrical insulating properties.
Rulon® 945 is best suited for use against hard mating surfaces like hardened steel substrates since it does have moderate abrasive qualities.
Rulon® 1045 – Dull gold coloured material that exhibits an excellent ability to elongate in a flip seal application. In addition
to outstanding frictional characteristics, Rulon® 1045 offers the added benefits of increased sealing efficiency as well as energy savings.
Low deformation properties allow Rulon® 1045 to be effective as a bearing or sliding surface.
Rulon® 1045 is resistant to many harsh chemicals found in the application environment where it is typically used. It is also compatible with
most commercially available lubricants for extra friction reduction.
Rulon® 1337 – A tan coloured material produced entirely from FDA compliant components. Rulon® 1337 demonstrates excellent physical
properties and is chemically compatible with most chemicals except concentrated sulphuric acid. Wash down of food areas and pharmaceutical
processing environments are typical of where this material offers much flexibility.
Rulon®1337 is compatible with most commercially available natural lubricants for improved reduction in friction.
A slightly lower coefficient of friction than Rulon® J allows this material to offer extended life and less abrasion with softer mating surfaces.
Chemical resistance is similar to Rulon® AR. If you require specific information regarding Rulon® 1337, please forward your
technical requirements to email@example.com

Rulon® 1410 can also be used as a liner material for substrates requiring any of the above characteristics.
Rulon® 1439 – FDA compliant white material suitable for immersed service with improved wear characteristics over most other PTFE compounds. The
white colour makes Rulon® 1439 aesthetically beneficial for food and pharmaceutical applications.
The properties of Rulon® 1439 allow it to effectively be utilised as a bearing or sliding surface.
Resistant against many harsh chemicals found in the application environments where it is typically used. Rulon® 1439 is compatible with most
commercially available lubricants for an improved reduction in friction. If you require specific information regarding Rulon® 1439 and its
