Key Features & Applications
- Long-Profile Design (L): Extended length (91.9 mm) delivers enhanced rigidity, moment resistance, and motion stability compared to standard carriages, ideal for long-stroke systems.
- Six-Row Full-Complement Balls: Maximizes load-carrying capacity in all directions with smooth operation, suitable for moderate to high loads.
- Light Preload (V1): Minimizes internal clearance with low friction, ideal for applications prioritizing smooth movement over maximum rigidity.
- Standard Precision (G3): Balances precision and cost, suitable for general industrial automation requiring reliable positioning.
- X-Life Quality: Premium materials and heat treatment ensure long service life, high wear resistance, and consistent performance.
- Wide Compatibility: Matches all KWSE20-series guide rails; widely used in packaging machinery, material handling systems, general machine tools, and industrial automation equipment.
Suffix Explanation
- L: Long-profile linear carriage.
