Key Design & Features
- High, Narrow (H) Design: Compact, slim-width (44mm) carriage with standard height (30mm), ideal for space-constrained installations requiring high rigidity.
- Six-Row Full-Complement: Eliminates ball cage to maximize ball count, delivering 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 high moment resistance.
- Light Preload (V1): 0.04C light preload ensures zero backlash with smooth, low-friction motion.
- G3 Precision: Manufactured to ISO 14728 G3 accuracy for reliable precision positioning.
- Robust Sealing: Double-lip end seals + side seals protect against contamination, extending service life.
- Easy Maintenance: Integrated lubrication holes enable convenient re-greasing without disassembly.
- Interchangeability: Fully interchangeable with INA TKSD20 rails and standard accessories.
