Key Design & Features

Six-Row Full-Complement Design: Eliminates the ball cage to maximize rolling element 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 & Moment Resistance: Induction-hardened and precision-ground raceways ensure outstanding static and dynamic rigidity, providing excellent resistance to pitching, yawing, and rolling moments under heavy loads.
Light Preload (V1): Implements 0.04C light preload to achieve zero backlash while maintaining smooth, low-friction motion, perfect for precision machines with moderate dynamic loads.
G2 Precision Class: Manufactured to ISO 14728 G2 accuracy standards, guaranteeing tight tolerances for high-precision positioning and repeatability.
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, reducing downtime.
Interchangeability: Fully interchangeable with standard INA TKSD45 rails and accessories, simplifying system design, installation, and inventory management.
