Duralon ® is a registered trademark of Rexnord Corp. 11-29-05 Two sensor mounting slots are standard. They accept “round profile” magnetically operated sensors (shown on pages 12 & 13) which fit flush or below the bearing block surface. Toolbar is slightly narrower than the bearing block to allow side mounting without interfer- ence between the toolbar and the mounting surface. A gap of 0.030" is typical.

Duralon ® is a composite of a Teflon ® /Dacron ® fabric liner bonded to a supporting filament-wound, high strength, fiberglass and epoxy resin shell. Resistant to corrosion, moisture and temperature to 325°F, the bearing is reliable in any environment. It has an extremely high load bearing capacity, very low friction, and will not gall or score the piston rod (see physical properties in the table below).
