Key Design & Features
- Six-Row Full-Complement Design: Eliminates ball cage to maximize steel ball count, delivering exceptional load capacity. The 6-point contact geometry (4 rows at 45° for pressure, 2 rows at 60° for tension) uniformly absorbs forces and moments from all directions.
- High Rigidity: Induction-hardened and precision-ground raceways ensure outstanding static and dynamic rigidity, providing excellent resistance to pitching, yawing, and rolling moments.
- Light Preload (V1): Implements 0.04C light preload to achieve zero backlash while maintaining smooth, low-friction motion.
- G2 Precision Class: Manufactured to ISO 14728 G2 accuracy standards, guaranteeing tight tolerances for high-precision positioning and repeatability.
- Robust Sealing: Equipped with double-lip end seals and longitudinal side seals to prevent contamination ingress, extending service life in harsh industrial environments.
- Easy Maintenance: Features integrated lubrication holes for convenient re-greasing without disassembly.
- Interchangeability: Fully interchangeable with standard INA TKSD20 rails and accessories.
Suffix Interpretation
- KWSE20: Standard-profile six-row ball carriage for 20mm rails
