Stainless Steel Sliding Bearing for Shafts in Harsh Environments

A stainless steel expansion sleeve (also called a stainless clamping sleeve, taper-lock sleeve, or corrosion-resistant locking assembly) is a high-strength, anti-corrosion fastening component used to create a secure, keyless connection between shafts and hubs in demanding environments.

The stainless steel expansion sleeve is a precision mechanical coupling component designed for keyless connection between shafts and bores. Made of high-grade stainless steel, it offers exceptional strength, corrosion resistance, and durability in harsh operating conditions.

• Keyless Fixation: Hydraulic or mechanical expansion ensures secure clamping without keyway stress.
• Corrosion Resistance: AISI 304/316 stainless steel resists chemicals, moisture, and high temperatures.
• Zero Backlash: High concentricity guarantees precise power transmission.
• Reusable: Demountable without damaging shafts or bores, ideal for maintenance.

• Corrosion Resistance - Ideal for humid, chemical, or marine applications (e.g., food processing, offshore equipment).
• Hygienic & Non-Contaminating - Passivated surface meets FDA/EU standards for sanitary use.
• High Strength - Maintains clamping force under heavy loads (comparable to alloy steel).
• Temperature Tolerance - Performs in extreme cold (-50°C) or heat (+400°C with special grades).
• Zero Magnetic Interference - Suitable for MRI machines or sensitive electronics.

• Precision machinery (spindles, gearboxes)
• Marine & chemical equipment (shaft fixation in corrosive environments)
• Wind power & energy systems (couplings, rotor assemblies)
