Types of Rulon

Rulon AR

Rulon® AR is a derivative of the original Rulon® A material, and continues the tradition of chemical resistance and long wear, plus reliability for continuous, non-lubricated service.

Rulon AR
Rulon J

One of the original Rulon compounds, Rulon® J is a reinforced material that combines the best in wear and friction properties with superior value.

Rulon LR

Among the most popular variations of Rulon®, Rulon® LR is the “Go-To” material for general purpose bearing applications. Rulon LR has a superior chemical inertness, with a ceramic filler for better dielectric and thermal insulation.

Rulon W2

Designed with fresh water in mind, Rulon® W2 provides one of the best wear rates, plus low friction and good thermal dissipation in fresh water applications. Rulon W2’s key properties actually improve when wet, do not absorb moisture, and can help prevent shaft distress in a wetted environment.

Rulon 1045

Rulon® 1045 delivers the unique ability to elongate in a flip seal application for enhanced sealing efficiency. It also gives excellent friction resistance and is compatible with most commercial lubricants. And its low-deformation properties allow it to easily adapt to sliding surface bearing applications.

Rulon 123

Rulon® 123 is known for a high resistance to deformation, low friction and good thermal and electrostatic dissipation, the material is also compatible with most mating surfaces. It features a self-lubricating design and has a maximum operating temperature of 550°F (300°C).

Rulon 142

When you have a need for exceptional vibration resistance, superior mechanical strength, and good dimensional stability, consider the versatile Rulon®142. This low-deformation compound exceeds most materials in preventing catastrophic failures on machine tool guideways. It is also our most cost effective linear bearing material.

Rulon 488

With excellent wear — especially in extremely dry environments — Rulon® 488 is the material of choice for veneer dryer bearings used in plywood and similar industries. Rulon® 488 gives excellent wear and corrosion resistance, and is durable enough for use in hydrogen and natural gas compressors.

Rulon 1410

Rulon® 1410 offers similar properties to our Rulon® 1045 — both are good materials for applications requiring elongation, such as flip seals. Rulon® 1045 offers the added benefit of energy savings from increased sealing efficiency.

Rulon 1410
Rulon 1439

Rulon® 1439 is a white FDA compliant material that is suitable for immersed service with better wear characteristics than most other PTFE compounds. Its color makes it aesthetically pleasing for food and pharmaceutical applications.

Rulon 1439
Rulon XL

When your application involves aluminum substrates, depend on Rulon® XL to provide significantly-enhanced wear, even better than other materials. Tan colored and compatible with a range of mating surfaces, Rulon XL presents excellent outgassing capability for use in vacuum applications.

Rulon XL
Rulon 641

Rulon® 641 is manufactured from FDA compliant materials which possess excellent load and wear characteristics. It offers excellent, continuous non-lubricated service up to 10,000 PV – higher for intermittent service. While the load capacity of Rulon® 641 is generally limited to 1,000 psi at room temperature, deformation is a function of wall thickness, temperature and load.
