B66250HTL

  • Material: HTL
  • Thickness: 0.066"
  • Inner Dia.: 10.000"
  • Outer Dia.: 11.125"
  • Friction Ring

High Thermal Engaging (HTE) has the thermal capacity of Kevlar®, with improved consistency and shudder resistance for today's demanding applications.

  • Dark gray
  • .045" or .066" Thickness
  • Replacement for Tan or Kevlar material.

High Thermal Lockup (HTL) has high thermal and exceptional torque capacity required for the most demanding torque-holding applications.

  • Khaki
  • .066" Thickness

Extreme Torque Lockup (XTL) provides 30% more torque holding capacity than HTL and is only for extreme duty lockup applications.

  • Dark gray/green
  • .050" Thickness
  • Only available in a few sizes for severe applications

High Thermal Slipping (HTS) is designed for slipping applications which require high thermal capacity, and is the benchmark for consistency, durability and shudder resistance.

  • Gray/green
  • .045" or .066" Thickness
  • Replacement for spun-wound, woven or other carbon based materials.
