Product Description
The EF10 THK Bearing Unit is a precision housing unit designed for supported-side (non-locating) applications in ball screw drive systems. This block-design bearing unit is engineered to work in tandem with fixed-side support units, providing reliable radial support for ball screw assemblies.
Key Specifications:
- Inner Dimension: 10mm shaft diameter
- Bearing Configuration: 1x 608 ZZ deep-groove ball bearing
- Design Type: Housing unit with deep-groove bearing for non-locating (supported-side) arrangement
- Preload: Without preload - optimized for free-running support
- Mounting Style: Block design for secure installation
- Combination Series: Part of the EK/EF combination series for BNK precision ball screws with finished shaft ends
Performance Features:
- Material: High-quality steel construction ensures durability and longevity
- Sealing: Without seal - suitable for clean operating environments
- Scope of Delivery: Includes circlip for secure fastening
- Design Advantage: Deep-groove bearing configuration provides smooth radial support without axial preload constraints
Applications:
The EF10 is ideal for use as the supported-side bearing unit in precision ball screw assemblies, particularly suited for:
- BNK precision ball screw systems with finished shaft ends
- CNC machinery and automation equipment
- Industrial linear motion systems
- Precision positioning applications
- Clean, controlled operating environments where maintenance accessibility is important
The EF10 works seamlessly with EK fixed-side support units to provide a complete, balanced bearing support system for demanding precision applications.
