Key Design & Features
- High, Long (HL) Design: Extended-length (104.3mm), narrow-width (48mm) carriage with increased height (40mm), delivering maximum load capacity and rigidity in space-constrained setups.
- Six-Row Full-Complement: Eliminates ball cage to maximize steel ball count, providing exceptional load capacity in all directions (compression, tension, lateral).
- 6-Point Contact Geometry: 4 rows at 45° (pressure) + 2 rows at 60° (tension) for uniform force absorption and outstanding moment resistance.
- Light Preload (V1): 0.04C light preload ensures 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.
- Robust Sealing: Equipped with double-lip end seals and longitudinal side seals to prevent contamination ingress, extending service life.
- Easy Maintenance: Features integrated lubrication holes for convenient re-greasing without disassembly.
- Interchangeability: Fully interchangeable with INA TKSD25 rails and standard accessories.
