Grades of Rulon®
Rulon® LR is the best-known, most widely used Rulon® formulation and has a long reputation for high wear resistance, low friction, good electrical properties, and chemical inertness. Rulon® LR makes a great sleeve, flange, or thrust bearing. It can also be bonded to nearly any surface to provide wear resistance and reduce friction. Color: maroon.
Rulon® J is the best Rulon grade for aluminum and soft mating surfaces. It provides the lowest coefficient of friction of all Rulon® and provides good wear and abrasion resistance. Rulon® J can be run on non-ferrous and non-metallic mating surfaces such as 316 Stainless, brass, and other plastic. It is used in both bearing and seal applications, but is generally not suitable for use in alkaline or oxidizing acid solutions. Color: dull gold.
Rulon® 641 is FDA compliant and was specifically developed for food and drug applications. It is designed to run dry without any moisture or lubrication. Color: white.
Rulon® 142 material is used for extremely heavy loads, and it is ideal for linear bearing applications such as slide ways in machine tools and heavy equipment. It may also be used in expansion joints and bridge pads. Rulon® 142 material provides low friction, excellent non-lubricated wear properties, and good heat dissipation. It is etched on one side for adhesive bonding to the steel substrate and competes with Busak+Shamban’s Turcite® B product. Color: turquoise with a bronze tint.
Rulon® 123 is FDA compliant and is excellent for wet or submerged applications. It provides excellent service against soft and non-ferrous mating surfaces. Color: black.
Rulon® W2 is a black PTFE-based material developed for use in fresh-water applications. It exhibits low friction and excellent wear characteristics (one of the lowest wear rates in fresh water), as well as good thermal dissipation, preventing shaft distress. Its properties are enhanced when wet. Rulon® W2 is compatible with most metal substrates and soft mating surfaces, is DWGV (European) certified for applications in contact with drinking water, and is a good alternative to Rulon® J when superior chemical resistance is needed. Rulon® W2 should NOT be used on very soft mating surfaces or where electrical insulation is necessary. Color: black.
Rulon® AR was the first commercially available reinforced PTFE and is still quite popular today. It offers the best combination of flexibility and load-carrying properties and has high wear resistance, low friction, and good electrical and chemical properties. Rulon® AR fillers are ceramic in nature, so mating surfaces should be RC35 or harder. It’s used in seals, piston cups, and some bearings. Color: maroon.
