Key Design & Features
- Six-Row Full-Complement Design: Maximizes load capacity by eliminating the cage and packing maximum steel balls. The 6-row contact geometry (4 rows at 45° for pressure, 2 rows at 60° for tension) uniformly absorbs forces and moments from all directions.
- Long Carriage (L): Extended length (119.3mm) provides greater support span, significantly improving resistance to pitching, yawing, and rolling moments compared to the standard KWSE30. Ideal for long-rail, overhung, or high-disturbance loads.
- High Rigidity: Induction-hardened and precision-ground raceways deliver exceptional static and dynamic rigidity, ensuring stable, precise positioning under heavy loads.
- Light Preload (V1): Delivers zero backlash with smooth, low-friction motion, ideal for precision machines requiring moderate dynamics and high accuracy.
- Robust Sealing System: 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 TKSD30 rails and accessories, simplifying system design and inventory.
Suffix Interpretation
