  • One of the most popular and copied mill stands in the world.
  • Drive housing encloses all gears in oil tight case.
  • Precision Timken tapered roller bearings (inboard side).
  • Roller bearings, rotating in hardened sleeves (outboard side).
  • Features toggle-link gear train to maintain full gear mesh through entire top roll shaft adjustment.

  • Alloy steel roll spindles, carburized, hardened, and ground.
  • Hardened hex-type clamping nuts.
  • Micrometer screws to facilitate accurate adjustment of spindles after roll changes.
  • Toggle-type idler gears permit maximum roll adjustment but maintain constant gear mesh.
