Rulon ® LR
The best known, most widely used Rulon formulation. Rulon ® LR has a long reputation for high wear resistance, low friction, good electrical properties and chemical inertness. Not only does it make a great sleeve, flange or thrust bearing, it can also be bonded to nearly any surface to provide wear resistance and reduce friction.
Rulon ® J
This is the best Rulon grade for aluminum and soft mating surfaces. Rulon ® J provides the lowest coefficient of friction of all Rulons, and provides good wear and abrasion resistance. Because this grade is "all plastic", it can be run on non-ferrous and non-metallic mating surfaces such as 316 Stainless, brass, and other plastics. It is used in both bearing and seal applications, but is generally not suitable for use in alkaline or oxidizing acid solutions.
Rulon ® 641
This FDA compliant material was specifically developed for food and drug applications. Rulon ® 641 is designed to run dry without any moisture or lubrication.
Rulon ® AR
This was the first commercially available reinforced PTFE and is still quite popular. Rulon ® AR offers the best combination of flexibility and load-carrying properties. It has high wear resistance, low friction, and good electrically insulative and chemical properties. Since, its fillers are ceramic in nature, mating surfaces should be RC35 or harder. It is and used in seals, piston cups, and some bearings.
Rulon ® 142
A material for extremely heavy loads. Rulon ® 142 is ideal for linear bearing applications such as slideways in machine tools and heavy equipment, and may also be used in expansion joints and bridge pads. This material provides low friction, excellent unlubricated wear properties and good heat dissipation and is etched one side for adhesive bonding to the steel substrate. Rulon ® 142 competes with Busak+Shamban's Turcite ® B Slydway ® product.
Rulon ® 123
This FDA compliant material is excellent for wet or submerged applications. Rulon ® 123 provides excellent service against soft and non-ferrous mating surfaces.
