BF30 THK Bearing unit
The BF30 THK Bearing Unit is a standardized ball screw support unit designed for non-locating (floating) side applications in general ball screw drive systems. This block-design housing unit features a deep-groove ball bearing configuration, making it the ideal complement to fixed-side BK series units in precision linear motion assemblies.
Key Specifications:
- Inner Dimension: 30mm bore size
- Article Type: Housing unit for non-locating arrangement with deep-groove bearing
- Bearing Configuration: 1x 6206 ZZ deep-groove ball bearing
- Design Type: Block design for straightforward mounting and secure locating arrangement
- Material: Steel construction for durability and reliability
- Preload: Without preload—designed for floating-side support with radial load capacity
- Seal: Without seal (open design for compatibility with various operating conditions)
- Combination: Compatible with BK/BF support unit series for standardized ball screw applications
- Scope of Delivery: Includes circlip for secure assembly
Design Features:
The BF30 completes THK's standardized BK/BF bearing support system, providing non-locating support on the floating side of ball screw assemblies. The deep-groove ball bearing delivers reliable radial load capacity while accommodating slight axial movement, allowing the fixed-side BK unit to maintain precise preload control and positioning accuracy.
Applications:
Ideal for:
- General industrial ball screw assemblies requiring standardized support units
- CNC machinery and machine tool positioning systems
- Industrial automation equipment with precision linear motion requirements
- Mechanical drive applications demanding long-term reliability with minimal maintenance
- Systems requiring cost-effective floating-side bearing support without preload adjustment
As part of THK's comprehensive BK/BF bearing unit line, the BF30 offers standardized compatibility with precision ball screws while providing the deep-groove bearing support necessary for floating-side mounting in controlled preload systems.
