Rulon Rod Seals

Rulon ® is the Saint Gobain Performance Plastics tradename for a family of reinforced proprietary PTFE compounds. This unique family of materials compounds. This unique family of materials offers the combination of high compressive strengths, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. These materials are used in bearing and seal applications at temperature extremes from -400°F to +500°F
(-240°C to +260°C) with or without additional lubricants. Rulon ® materials also have the unique property of no "slip
stick" --- no erratic motion at low speeds.
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 orthrust bearing, it can also be bonded to nearly any surface to provide wear resistance and reduce friction. MAROON in color.
Where to use Rulon®:
Low cost, high performance dry bearing for continuous services to 20,000 PV or intermittent service to 50,000 PV.
Low temperatures to -400°F., where oils are useless.
High temperatures to 550°F.
Corrosive substances, non lubricating fluids, high or low humidity.
Lubricated applications where wear may occur during starting and stopping.
Oscillating bearings or any case where stick-slip is undesirable.
Space and weight-saving applications.
Where bearing lubrication is undesirable or impossible.
