Ultra-Glide™ 1/4" x 7/8" High Performance Ball Bearing Guide Assembly

Using the same quality standards as our regular steel bearings, these Ultra-Glide™ bearing assemblies feature satin-smooth Delrinr sleeves. Delrinr is an industrial synthetic plastic material similar to nylon, and will leave no marks on the material being cut. Applications include solid-surface materials such as Gibraltarr, Corianr, Surelyr & Fountainheadr. etc.; Plexiglasr & other clear acrylics; and plastic laminates. Not recommended for regular wood applications due to a higher wear factor. Include Teflonr dust shields. These bearings provide a better seal to increase bearing life while routing materials that generate very fine dust particles (such as solid surface). Includes new Teflonr dust shields.
