PTFE rod Rulon® XL

plate

Product summary
Rulon® XL is a tan-colored filled PTFE bearing material optimized for use against aluminum (including anodized) substrates. It exhibits very low wear compared with other Rulon® grades, low deformation under load and excellent chemical resistance. Its non-abrasive character reduces galling of softer mating surfaces. Rulon® XL also demonstrates excellent outgassing performance and is noted as particularly suitable for vacuum service. Avoid use with strong alkalis.

Advantages

• Very low wear compared with other Rulon® grades
• Low deformation under load
• Exceptionally good chemical resistance
• Compatible with a wide range of mating surfaces (avoid alkalis)
• Non-abrasive — reduces galling of softer mating surfaces
• Excellent outgassing capability — particularly suitable for vacuum service
• Recommended for moderate to high speed dynamic service running against soft metals
• Some source information is inconsistent regarding steam: parts of the source state it is not recommended for steam, while other parts indicate it can be used in steam, wet and dry environments

Applications

• Vacuum pumps, mixers, compressors, appliances, insulators, linear slides, shaft support, wear bands
