GUIDANCE

Bearings, roll bearings

Be sure the table is having a nice rotation, use the adequate roller bearing. From this choice depends the final aspect of the piece. Axial –radial bearing gather in one set a solution easy to install. It maintains geometry under heavy tilting efforts, keep a good concentricity under radial forces, and is few affected by workpiece weight. The concept allows high speed rotation. It can be associated as well to worm gear as to torque motor application.
