1/4" x 1" Ultra-Glide High Performance Ball Bearing

Using the same quality standards as our regular steel bearings, these Ultra-Glide bearing assemblies feature satin-smooth Delrin sleeves. Delrin 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 Gibraltar, Corian Surely and Fountainhead. etc. Plexiglas and other clear acrylics and plastic laminates. Not recommended for regular wood applications due to a higher wear factor. Include Teflon 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 Teflon dust shields. 1/4" of inner diameter. 12? of degree taper.
