Product Description
The FF30 THK Bearing Unit is a precision housing unit designed for non-locating (floating) side support applications in ball screw drive systems. This bearing unit provides flexible shaft positioning and accommodates thermal expansion, making it an essential component in high-precision linear motion applications when paired with a fixed-side FK bearing unit.
Key Specifications
- Inner Dimension: 30mm shaft diameter
- Bearing Configuration: 1x 6206 ZZ deep-groove ball bearing
- Design: Flange design for easy mounting and integration
- Preload: Without preload - allows free floating motion for thermal compensation
- Seal Type: Without seal - open design for low-friction operation
- Material: Steel construction for durability and load capacity
- Compatibility: FK/FF combination model, part of THK's precision ball screw support system
- Scope of Delivery: Includes circlip for secure shaft retention
Features & Benefits
- Deep-groove ball bearing (6206 ZZ) ensures smooth rotation with minimal friction
- Non-locating design allows axial shaft movement to accommodate thermal expansion and contraction
- Open seal design reduces operating resistance and maintenance requirements
- Flange design provides secure, rigid mounting in various industrial applications
- Preload-free configuration simplifies installation and reduces assembly complexity
- Works seamlessly with FK fixed-side units for complete ball screw support systems
Typical Applications
- CNC machine tools and precision machining centers
- Industrial automation equipment
- Semiconductor and electronics manufacturing systems
- Medical device machinery
- High-precision linear motion systems requiring thermal compensation
- Ball screw drive systems where floating bearing support is required
