Extremely smooth sliding is realized.
By building in a high accuracy holder to the finite stroke type that has no resistance against steel ball circulation, variations in the sliding resistance value is made extremely minimal, and a light and smooth sliding is realized even in case it is used for vertical axis.
Although the Design is Compact, it boasts High Rigidity and High Accuracy
Since it adopts a structure in which steel balls of large diameters are arranged in two rows, and are made to come into contact with the track at 4 points, while it realizes small compact size of the outer cylinder outside diameter against the axial diameter, it exhibits high rigidity in all directions.
Since a suitable preload is added, there is no gap in the rotating direction, and an accurate positioning is possible.
