Roll Coverings

Valley Rubber pulley lagging and roll covering provides superior coefficient of friction – and meets high standards for reliability. We have years of experience in factory compounding and applying a variety of rubbers to pulleys and rollers – including:

  • MSHA approved FR-IC-163/1 Neoprene – Special fire resistant material
  • Viton – High temperature (600° F)
  • High release and temperature resistant (500° F) Silicone
  • Nitrile – Oil and abrasion resistant
  • Hypalon – Chemical and abrasion resistant
  • EPDM – Acid and ozone resistant
  • High tensile and high rebouond natural rubber
  • Carboxylated Nitrile – 85 durometer proprietary blend – which has been shown in various field applications to outwear polyurethane
  • Rubber/Ceramic – Hot Vulcanized Lagging
  • Plus – Silicone, Natural Rubber, Neoprene, SBR and more

Benefits of Our Rubber Lagging

  • Quick turnaround
  • Wide variety of covering compounds
  • Certified fire resistant compound
  • All covering ground for concentricity to bearing journals
  • Large diameter, up to 60″ (Up to 63″ in certain applications)
  • Industrial rolls, up to 14 ft. long
  • Pulley repair if necessary
  • Balancing of pulley if requested
  • Variety of surface finishes
    • Crowned
    • Plain
    • Chevron
    • Diamond
  • Hot vulcanized ceramic lagging

Benefits of Our Ceramic Lagging

  • Superior Bonding through hot vulcanizing to the pulley
  • Exceptional bonding strength between the rubber and the ceramic tile
  • Ceramic tile – 92% Alumina Oxide
  • Increased co-efficient of friction values
  • Excellent Performance in wet and muddy applications
  • Superb Performance under dry conditions
  • Unmatched wear performance, durability and load carrying capabilities due to special wear resistant ceramic tiles, advanced rubber compound, and vulcanization process
  • Improved traction, stability and belt aligning capabilities
  • Sophisticated appearance due to the innovative lagging design, especially developed for the most extreme applications

Our vulcanization method is superior to cold-bonding methods.
