Product Description
The BF17 THK Bearing Unit is a standardized housing unit designed for non-locating (free) side support in ball screw applications. This block-design unit provides reliable support and smooth linear motion using a single deep-groove ball bearing, complementing fixed-side bearing units in dual-bearing screw assemblies.
Key Specifications:
- Inner Dimension: 17mm bore size
- Bearing Configuration: Single 6203 ZZ deep-groove ball bearing
- Arrangement Type: Non-locating arrangement for free-side support
- Preload: Without preload - allows for axial freedom and thermal expansion accommodation
- Sealing: Sealed bearing (ZZ designation) provides basic contamination protection
- Material: High-quality steel construction for durability
- Design: Block-type housing for easy mounting and secure locating
- Scope of Delivery: Includes circlip for secure shaft retention
Applications:
The BF17 is ideal for:
- General industrial ball screw assemblies as the free-side support unit
- Machine tool positioning systems requiring dual-bearing support
- Automation equipment with precision linear motion requirements
- Systems where thermal expansion accommodation is necessary
- Applications paired with BK-series fixed-side bearing units
As part of THK's comprehensive BK/BF bearing unit line, the BF17 offers standardized compatibility with precision ball screws while delivering the deep-groove bearing support necessary for non-locating (free) side mounting with minimal maintenance.
