- Open Type (OP) Design: Specially engineered with a side opening to allow travel over supported shafts (shafts mounted on continuous rails). This configuration is essential for long-stroke systems where shaft deflection must be prevented.
- Optimized 20 mm Bore: Provides a balanced ratio between size and load capacity, making it a standard choice for medium-duty CNC routers and automation lines.
- Polyamide Cage: Features a high-quality resin cage that reduces friction, noise, and vibration during high-speed linear travel.
- Integrated UU Seals: Equipped with protective rubber seals on both ends. These seals are notched to match the open profile, ensuring that dust is excluded and lubricant is retained within the ball circuits.
