THK Retainer Ball Spline "SLS/SLF"
Achieving high speed, low noise, and long lifespan! The SLS/SLF type, which expands THK's retained technology into ball splines, is newly introduced!
[Features] ○ High-speed response → The adoption of a ball retainer maintains a aligned circulating motion, enabling high-speed response and allowing for high takt time of the device. ○ Low noise, good sound quality, low dust generation → The use of a ball retainer eliminates collisions and mutual friction between balls, achieving low noise, good sound quality, and low dust generation. ○ Long-term maintenance-free → The significant improvement in grease retention capability due to the adoption of a ball retainer enables long-term maintenance-free operation. ○ Smooth operation (small rolling variation) → The adoption of a ball retainer and a new circulation method achieves stable and smooth movement with small rolling variations.

Detailed information
-
"SLS" (Medium Load Type) The outer diameter of the spline nut has a straight cylindrical shape. It can be fixed to the housing using a key, allowing for torque transmission.
-
"SLS-L" (Heavy Load Type) This is a heavy load type with a longer spline nut that has the same outer diameter as the "SLS." It is ideal for situations where high torque is applied in areas with limited space or where overhang loads and moments are present.
-
"SLF" It is a flange type that can be fixed to the housing with bolts. Assembly is easy, and compared to fixing with keys, it allows for a shorter housing length.
