Rod RPTFE Rulon® 142

sheetrolltubular

Overview
Rulon® 142 / 142S / 242 are metal-filled PTFE-based bearing materials formulated in a dull blue-green color. They provide low wear, good dimensional stability, high thermal dissipation and effective vibration damping for linear bearing and sliding applications. Strong acids and bases should be avoided as they can attack the metal-filled fillers.

Benefits & Features

• Virtual elimination of stick-slip
• Effective vibration dampening
• Self-lubricating behavior
• Uniform and predictable friction
• Long service life with low deformation
• Easy to machine and adaptable to diverse designs

Typical Offerings & Product Forms
Available as packings, stamped parts, extruded profiles, machined components, molded shapes, wear bands and seal rings. Materials are supplied molded and precision-machined from high-performance PTFE and filled PTFE composites to control wear and friction for specific environments.

Applications

• Linear bearings and slides
• Machine tool components (gibs, guideways, rotary tables, lathe parts)
• Compressors and hydraulic presses
• Piston rings, molded bearings and related components
• Motor mounts, pipe supports, appliances and parts requiring vibration damping and dimensional stability
• Suitable for wet, dry and vacuum environments
