STK400/Z18 Expansion Sleeve Shaft Locking Device – Bore Diameter 25 to 40 mm, CNC Tool Fastening Sleeve

The STK400/Z18 Expansion Sleeve is a high-precision shaft locking device with a keyless connection structure, designed for use in various CNC tools and mechanical assemblies. Utilizing axial force, this device enables the inner and outer sleeves to shrink and expand, providing a secure fit between the shaft and hub. This tight fit generates enough friction to efficiently transmit torque, ensuring reliable and smooth mechanism operation in high-performance applications.

Key Features:

  • Keyless Connection: Features a keyless connection structure, eliminating the need for traditional keyways while providing a secure grip on the shaft and hub.
  • Axial Force Mechanism: Uses axial force to shrink and expand the inner and outer sleeves, ensuring a tight fit and maximizing torque transmission.
  • High Friction Fit: Generates enough friction to transmit torque, making it ideal for high-load and precision applications in CNC tools.
  • Wide Bore Diameter Range: Suitable for shafts with bore diameters ranging from 25 mm to 40 mm, offering flexibility for various mechanical assemblies.
  • Efficient Mechanism Operation: Enhances the reliability and lifespan of machinery by providing a play-free and vibration-resistant fit.
