THK'S New Types SLS/SLF Ball Splines Feature Caged Technology
for Even Smoother Motion
 Schaumburg, IL - (September 5, 2006) With the addition of
its Types SLS/SLF, THK combines Caged Technology with its
successful ball spline design.
The ball spline is a direct motion system in which the balls
embedded in the spline's external nut can convey torque while
making smooth linear motion in the rolling groove of the
precisely ground spline shaft. The incorporation of THK Caged
Technology, and an optimized design of the ball circulation
path, enhances this smooth movement in even vertical applications.
THK Caged Technology employs a synthetic resin cage with
a patented curvature that cradles each ball and separates
it from the next. The spaces between the rolling elements
retain grease and act as a lubrication system for long-term
maintenance-free operation. Additional benefits of Caged
Technology for the Types SLS/SLF include high-speed operation
due to evenly spaced balls, high rigidity equivalent to an
LT shaft (±10%) and low noise with the use of a resin
circulation path and optimum ball diameter.
Types SLS/SLF are available in spline shaft outer diameters
from 15 to 100 mm. They are interchangeable with THK's Type
LBS. Application examples using Type SLS/SLF include inspection
machine, medical equipment, wafer transfer, printing machine
and pressing machine.
THK manufacturers the widest range of linear motion products
including conventional LM guides, ball screws, mechanical
actuators and ball splines and more. All THK products have
been designed and manufactured to meet the strictest requirements.
THK's experienced Global Engineering Team can provide customized
linear motion solutions with our standard linear motion products
as well as our mechatronics products for your most demanding
applications.
