When used in place of a linear bush, the Ball Spline can be provided with a compact design, as it has a load rating more than ten times greater than that of a linear bush with the same shaft diameter. Capable of withstanding overhanging loads and moments, the THK Ball Spline provides a high degree of safety and an extended service life.
Ball Spline types LT and LF have four or six trains of load-bearing balls to hold two or three crests on the spline shaft from both sides, so that an appropriate preload is unforcedly applied.
