Product Description
The EF6 THK Bearing Unit is a precision ball screw bearing support unit designed for non-locating (floating) side mounting applications. This block-design housing unit is engineered to work seamlessly with THK's precision ball screw systems and is ideal for applications requiring flexible shaft support with minimal radial load constraints.
Key Specifications:
- Inner Dimension: 6mm shaft diameter
- Bearing Configuration: 1x 606 ZZ deep groove ball bearing
- Housing Type: Block design for compact, flexible mounting
- Combination Type: EK/EF compatible pairing for complete ball screw support systems
- Material: Steel construction for durability and reliability
- Preload: Without preload - designed for non-locating arrangement
- Seal Type: ZZ seals (contact seals) for basic protection
- Scope of Delivery: Includes circlip for secure installation
Performance Features:
- Non-Locating Design: Deep groove ball bearing allows axial shaft movement, making it ideal for the floating end of ball screw assemblies
- Flexible Support: Without factory preload, this unit accommodates thermal expansion and shaft movement while maintaining smooth operation
- Compact Mounting: Block design enables space-efficient installation in confined spaces
Applications:
The EF6 is an excellent choice for precision machinery requiring flexible linear positioning, including:
- Industrial automation equipment
- Machine tools and CNC systems
- Precision assembly systems
- Automated manufacturing machinery
- General-purpose precision positioning applications
When paired with a fixed-side FK or EK bearing unit, the EF6 completes a robust, standardized ball screw support system capable of reliable long-term operation with minimal maintenance requirements.
