Flat Roller

For the flat roller, a precision roller compliant with JISB 1506 is installed in the pocket of the cage whose weight is reduced and rigidity is improved by press forming a steel plate into an M shape. The roller has a structure retained in the cage pocket so as to not drop off. This flat roller is used between the two raceways, so it moves in the same direction as that of the table by only half of the amount the table moves. For example, if the table moves by 500 mm, the flat roller moves by 250 mm in the same direction.
The flat roller is ideal for large machine tools such as planers, horizontal milling machines, and cylindrical grinding machines, in addition to locations requiring high accuracy such as surface grinding machines, cylindrical grinders, and optic measuring machines.
