These 1" diameter ball bearing rollers are perfect for creating your own outfeed roller tables or conveyor system. Unlike rollers which operate only in a straight line, these 360º universal transfer bearings are particularly suited for curved work created on band saws and router tables as well as straight cutting on bench saws and miter saws. Featuring two screw holes in each bearing surround for solid attachment to the worktable or workbench. Each bearing has a maximum load rating of 110lbs.
