Ball bearing PTFE Rulon® 1337

rodsheetroll

Product Overview Rulon® 1337 is a tan PTFE-based material composed entirely of FDA- and USDA-compliant components. It provides excellent physical properties and broad chemical compatibility (except concentrated sulfuric acid), making it suitable for wash-down environments in food and pharmaceutical processing. It has a slightly lower coefficient of friction than Rulon® J, resulting in extended service life and reduced abrasion against softer mating surfaces. Compatible with most commercially available natural lubricants for additional friction reduction.

Key Benefits

• FDA and USDA compliant formulation for food and pharmaceutical wash-down environments
• Lower coefficient of friction vs Rulon® J for extended life and reduced abrasion on softer surfaces
• Compatible with most commercially available natural lubricants to further lower friction
• Chemically compatible with the majority of chemicals (except concentrated sulfuric acid)
• Good dimensional stability and minimal moisture absorption; suitable for wet, dry and vacuum conditions

Applications

• Pumps
• Mixers
• Compressors
• Appliances
• Chute liners
• Insulators
• Linear slides
• Shaft bearings
• Seals
• Wear bands
