Some of our largest competitors use a cheaper alumina-ceramic sleeve to make their liners. Although these liners last a little longer than standard chrome-iron liners, they only last about half as long as zirconia-ceramic liners. Our liners are made from zirconia-ceramic material in order to provide the longest life and best wear performance.

Features include:

  • 90 – 92 Rockwell C bore hardness
  • Zirconia-Ceramic sleeve press fit and honed to size
  • Ceramic sleeve press fit and secured by safety lip
  • Forged steel hull
  • Available in sizes from 4-1/2" to 7"
  • Significantly outlasts inferior alumina-ceramic liners
