Key Features & Applications
- Extreme Load Capacity: Full-complement four-row roller configuration delivers exceptional dynamic and static load ratings, suitable for heavy-duty machinery.
- High Rigidity & Stability: Medium preload (V3) eliminates clearance, enhancing rigidity, positioning accuracy, and resistance to deflection under complex loads.
- High, Narrow, Long Design (HL): Optimized for applications requiring elevated height, reduced width, and extended support length, improving moment resistance.
- Smooth & Precise Motion: Precision-manufactured roller raceways ensure low friction, consistent travel, and high repeatability.
- Wide Compatibility: Matches RWU45 series linear guide rails, suitable for CNC machine tools, automation lines, precision presses, and heavy industrial equipment.
Suffix Explanation
- E: Standard linear recirculating roller bearing system.
- HL: High, narrow, long carriage design.
- V3: Medium preload class (standard preload).
