INA Linear Guide Carriage KWSE25-V1
The INA KWSE25-V1 is a six-row, full-complement ball linear guide carriage from Schaeffler's KWSE series (part of the KUSE linear guide system). Engineered for exceptionally high load capacity, rigidity, and precision, it features a standard-profile design with light preload, ideal for heavy-duty linear motion applications requiring stable, accurate positioning under combined loads. It is compatible with INA TKSD25-series guide rails.

Key Design & Features
- Six-Row Full-Complement Balls: Maximizes load capacity with maximum rolling elements; four rows at 45° (pressure load) and two rows at 60° (tension load), absorbing forces from all directions.
- High Rigidity & Moment Resistance: Optimized for high static/dynamic rigidity and excellent resistance to tilting, yawing, and rolling moments.
- Light Preload (V1): Delivers zero backlash with smooth motion, suitable for precision machines with moderate dynamic loads.
- Full-Complement Design: Eliminates cage, increasing ball count for superior load capacity vs. standard four-row carriages.
- Robust Sealing: Dual end seals and perimeter seals protect internal components from dust, chips, and fluids.
- Easy Lubrication: Integrated lubrication holes enable convenient re-greasing without disassembly.
- Precision Manufacture: Carriage and rail raceways are induction-hardened and precision-ground for consistent accuracy.
Suffix Interpretation
- KWSE25: Standard-profile six-row ball carriage for 25mm rails
- V1: Light preload (0.04C)
- (Accuracy class G2/G3/G4 typically added as suffix, e.g., KWSE25-V1-G2)
Typical Applications
- Heavy-duty CNC machine tools (milling, boring, grinding machines)
- Large-scale automation and material handling systems
- Industrial robots and precision positioning stages
- Machine building with high load/rigidity demands
- Packaging, printing, and textile machinery
- Precision measuring and testing equipment
