Ball bearing PTFE Rulon®

rodsheetgranular

Overview
Omniseal Solutions supplies genuine Rulon® PTFE-filled fluoropolymer compounds, originally developed in the 1950s (Rulon® A). Available in hundreds of formulated grades, Rulon® materials are engineered for manufacturing bearings, piston rings, cup seals, wear components and other critical parts across industrial sectors.

Key properties
Rulon® materials provide a low coefficient of friction, long wear life, strong abrasion resistance, chemical inertness and the ability to perform across wide temperature and pressure ranges.

Typical solutions and applications

• Bearings
• Piston rings
• Cup seals
• Formed parts and wear components
• Basic shapes (molded and extruded rods, tubes and sheets)

Material grades and color cues
Distinct fillers produce identifiable grades and color cues used for grade identification (for example: LR is maroon, J is gold, W2 is black, 641 is white). Fillers modify mechanical and tribological characteristics to extend application range.

Processing methods
Materials are processed by automatic and hand molding, extrusion, machining, skiving, stamping and forming. The chosen method depends on component geometry and intended end-use (e.g., automatic molding for bearings, skiving for sheets).

Features & benefits

• Excellent wear resistance
• Friction control (low friction)
• Superior chemical and corrosion resistance
• Low weight solutions

Examples of typical grades / use-cases

• LR – general-purpose, compatible with hardened steel substrates and chemically inert to most commercial chemicals
• J – optimized for softer mating surfaces and extreme cold temperatures
• W2 – carbon-filled grade developed for fresh-water applications with strong wear performance when wet
• 641 – FDA/USDA-compliant grade for food and pharmaceutical bearing applications

Technical specifications

• Low coefficient of friction
• Long wear life and strong abrasion resistance
• Chemical inertness (resistant to most chemicals except specific aggressive reagents)
• Capable of continuous service across a wide temperature and pressure range
• Available in hundreds of formulated grades to tailor mechanical, thermal and tribological performance
• Typical form factors: powders, molded shapes, extruded rods, tubes, sheets, finished machined components
• Processing options: molding (automatic, hand), extrusion, machining, skiving, stamping, forming
• Certain grades available with regulatory compliance (e.g., FDA/USDA/USP classifications for food/pharma use)
