Product Description
The FF6 THK Bearing Unit is a precision housing unit designed for free-side support applications in ball screw drive systems. This flange-design bearing unit is engineered to accommodate axial float while maintaining smooth linear motion in demanding applications.
Key Specifications:
- Brand: THK
- Article Type: Housing unit for non-locating arrangement with deep groove ball bearing
- Inner Dimension: 6mm
- Bearing: 1x 606 ZZ (deep-groove ball bearing)
- Configuration: FK/FF combination
- Material: Steel
- Design: Flange design for secure mounting
- Preload: Without preload
- Seal: Equipped with ZZ shielded design for basic contamination protection
- Scope of Delivery: Includes circlip for secure installation
Performance Features:
- Deep-Groove Configuration: Allows for axial float, making it ideal for the supported (free) side of ball screw assemblies
- Compact Design: The 6mm inner dimension makes this unit suitable for smaller precision applications
- Low-Friction Operation: Designed without preload for minimal resistance and smooth rotation
- Shielded Bearing: ZZ shields provide protection against dust and debris while maintaining operational efficiency
Applications:
The FF6 is ideal for use as a free-side support unit in precision ball screw assemblies, particularly in:
- Compact CNC machinery and automated equipment
- Precision linear motion systems with smaller shaft diameters
- Laboratory and medical instrumentation
- Applications requiring minimal preload and smooth axial movement
- Systems paired with fixed-side support units for complete ball screw drive assemblies
This bearing unit combines deep-groove ball bearing technology with a practical flange design, making it suitable for reliable operation in both industrial and precision engineering environments where a floating support point is required.
