The rotary ball spline can be used for both rotational motion and linear motion. It can be used in scalar robots, the vertical shaft of assembly equipment, and tool changers and loaders.
Istotech Rotary Ball Splines consists of a spline shaft and a nut. The nut has a spline portion and a rotating portion.
Reduced Number of Parts
Because of the single-body construction consisting of the rotating portion which is equipped with cross roller elements and the spline portion, the number of parts is reduced and the cumulative installation error is reduced.
Compact and Light
The cross roller is directly attached to the ball spline’s external cylinder, resulting in a compact and light design.
