90A / 75D DUAL DUROMETER URETHANE TUBE - DARK BLUE OUTER CORE

3/4" ID X 1-1/2" BEARING OD X 3-7/16" OD X 24" LONG P/N 11546

ITEM MAY HAVE SLIGHT BLEMISHES OR SURFACE IMPERFECTIONS

A low-cost alternative for wheels, casters, rollers, sheaves, etc.

  • Two grades urethane permanently bonded together, resulting in a hard anti-friction hub with softer outer tire.
  • 75 D durometer hub can serve as a bearing in some applications.
  • ID’s, OD’s, lengths and profiles can be machined to fit your application.
  • Use to make low cost OEM components for your manufactured products.
  • Nominal OD’s +/-  2%
  • I.D.’s are slightly oversized to provide running clearance
  • Custom shapes & sizes are available!

ALL DIMENSIONS ARE NOMINAL. TOLERANCE ON ID, OD, AND THICKNESS IS +/- 2% AND LENGTH AND WIDTH IS +/- 1/4".
