Key Features & Design
- Four-Row Full-Complement Balls: Maximizes load capacity and rigidity by using the maximum number of rolling elements.
- Integrated Sealing: Equipped with end seals and sealing strips to protect against contaminants (e.g., dust, metal chips).
- Lubrication System: Features lubrication connectors for easy relubrication; pre-greased for initial use.
- High Rigidity: Optimized for moment load resistance (X/Y/Z axes) and stable positioning.
- Interchangeability: Compatible with standard KWVE20-series rails and accessories, simplifying installation and inventory management.
Suffix & Naming Notes
