Key Features
- 4-Way Equal Load CapacityThe 45° contact angle configuration ensures equal load resistance in radial, reverse-radial, and lateral directions, enabling versatile mounting in any orientation.
- High Rigidity & Auto-AdjustmentTHK’s proprietary Gothic arch groove design (DF arrangement) delivers self-aligning capability, absorbing installation errors to maintain backlash-free, smooth motion.
- Ball Retention StructureThe integrated ball retainer prevents balls from dislodging when the block is removed from the rail (excluding HSR8/10/12 models).
- Universal StandardizationComplies with global size standards, ensuring interchangeability with other HSR-series models for easy system integration.
- Low Friction & Long LifePrecision-ground ball grooves minimize differential sliding under preload or offset loads, ensuring low friction, high wear resistance, and long-term precision retention.
Typical Applications
- CNC machine tools (milling, lathe machines)
- Heavy-duty industrial robots
- Precision measuring instruments
- Injection molding machines
- Automated handling/conveying systems
- Medical diagnostic equipment
