BF35 THK Bearing unit
The BF35 THK Bearing Unit is a precision housing unit designed for floating-side support applications in ball screw drive systems. This block-design bearing unit is engineered to provide reliable, cost-effective linear motion support in standardized ball screw assemblies.
Key Specifications:
- Brand: THK
- Article Type: Housing unit for non-locating arrangement with deep groove bearing
- Inner Dimension: 35mm shaft diameter
- Bearing: 1x 6207 ZZ deep-groove ball bearing
- Configuration: BK/BF combination for standardized ball screw systems
- Material: Steel construction for durability
- Design: Block-mount configuration for flexible installation
- Preload: Without preload - optimized for floating-side support
- Seal Type: Without seal - standard design for general applications
- Scope of Delivery: Includes circlip for secure mounting
Performance Features:
The BF35 utilizes a single deep-groove ball bearing to accommodate axial and radial loads while allowing for thermal expansion and contraction. As a non-locating (floating-side) support unit, it works in tandem with a fixed-side bearing unit (BK series) to create a complete ball screw support system.
Applications:
The BF35 is ideal for use as a floating-side support unit in standardized ball screw assemblies, particularly in:
- Industrial automation equipment
- Machine tools and CNC systems
- General-purpose linear motion applications
- Cost-sensitive automation systems
- Standard precision machinery requiring reliable support
This bearing unit provides a practical solution for applications where floating-side support is required, delivering dependable performance in standard ball screw drive systems without the added complexity of preloading mechanisms.
