INA Linear Roller Carriage RWU45-E-L-V3
The RWU45-E-L-V3 is a long-type, four-row linear recirculating roller bearing carriage from INA (Schaeffler Group), part of the RWU45 series. It features a full-complement roller design, standard E-type roller system, and medium preload (V3). Engineered for high-load, high-rigidity applications requiring extended moment support and precise linear motion.

Key Features & Applications
- High Load & Moment Capacity: Four-row full-complement roller design delivers exceptional static/dynamic load ratings and enhanced moment resistance, ideal for heavy-duty machinery.
- Long Carriage (L): Extended length (178.3 mm) improves stability under overhung loads and increases support span, suitable for long-stroke systems.
- Medium Preload (V3): Eliminates internal clearance, boosts rigidity, and ensures precise positioning accuracy under variable loads.
- Smooth Motion: Precision-ground raceways minimize friction, enabling consistent, low-vibration travel over long distances.
- Versatile Compatibility: Matches all RWU45-series linear guide rails; widely used in CNC machine tools, automation lines, presses, and heavy industrial equipment.
Suffix Explanation
- E: Standard linear recirculating roller bearing system.
- L: Long-type carriage (extended length).
- V3: Medium preload class (standard preload).
