THK Ball Splines
The Ball Spline is an innovative linear motion system, in that
balls accommodated in the spline nut transmit torque while linearly
moving on precision-ground raceways on a spline shaft.
One significant
difference between this design and a conventional design of this
kind is that a single spline nut can exert a preload. As a result
of this ability, the THK Ball Spline is well suited for use under
severe service conditions involving vibration and the application
of impact loads, and in locations that require highly precise
positioning and high-speed operation. |
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. |

The balls
are held in place by the retainer, which is made of special
synthetic resin, and is built into the
interior of the spline nut. The retainer causes the balls
to circulate in line and prevents them from falling off
if the spline shaft is removed. THK
