INA Linear Guide Carriage RWU25-E-H-V3-G1
The INA RWU25-E-H-V3-G1 is a high, narrow carriage with full-complement roller recirculation from Schaeffler's RWU-E-H series. Designed for ultra-high load, high-rigidity linear motion, it delivers exceptional moment load resistance across all axes and ultra-precise positioning for heavy-duty machinery. It is compatible with standard TSX25 linear guide rails and suitable for oil or grease lubrication.

Key Features & Design
- Full-Complement Rollers: Maximizes load capacity and rigidity via maximum rolling elements; line contact for high stiffness.
- High/Narrow Profile (H): Compact footprint ideal for space-constrained, high-load designs.
- Integrated Sealing: Equipped with end seals and sealing strips to resist dust, metal chips, and contaminants.
- Lubrication System: Features relubrication connectors for easy maintenance; pre-greased for initial use.
- High Rigidity: Excels in resisting X/Y/Z axis moments and stable positioning under heavy loads.
- Interchangeability: Matches standard TSX25 rails and accessories, simplifying installation and inventory management.
Suffix & Naming Notes
- E: Full-complement roller recirculation system, oil/grease lubrication.
- H: High/narrow carriage design.
- V3: Heavy preload (0.12C); other options: V1 (light), V2 (medium).
- G1: Ultra-precision accuracy class (ISO 14728).
