The Stelron SSF Series Anti-Friction Slide is an extension of the SS & SSP Series. This unit permits mounting in a position perpendicular to that normally used for other units. In addition, an external pilot diameter is provided to allow accurate positioning of the slide axis when alignment is an important consideration. Integral felt wipers protect and lubricate the bearings, assuring low friction and long life. Since the internal construction is identical to that of the SSP Series, the same general engineering data is applicable to both types of units.
