These 5/8" & 1" diameter ball bearing rollers
are ideal for creating your own out feed roller
tables. As the steel balls rotate through 360 degrees
they are particularly suited for curved work created
on band saws and router tables as well as straight
cutting on saw benches and miter saws. There are
two screw holes in each bearing surround for positive
attachment to the worktable.They provide low friction support for most any type of material. Whether you build a table with rollers on it or a simple roller stand, the rollers on it will provide you with an easy and smooth transition from one platform to the next when traveling across them. Simply install them by securing each roller ball to your desired mount with the screws that are provided. Add more roller to make more elaborate jigs or fixtures like a finishing table, table saw extension, band saw out feed table and more. The Roller Balls are made from hardened steel and encased in a durable steel housing, each roller has a load rating of 75lbs.
