Shrink Fitting

We deliver expert Shrink Fitting Services using liquid nitrogen for industrial, mechanical and engineering applications. Our experienced team works across London, Kent, Essex, Surrey, West Sussex, East Sussex, Hertfordshire and beyond – read our recent project.

The Shrink Fitting Process uses ultra-cold liquid nitrogen to contract metal parts before assembly. As the part returns to room temperature, it expands to form a precise and permanent fit. This method removes the need for welding and avoids distortion to the component.

Why Use Shrink Fitting?

Shrink fitting offers superior strength compared to press fitting or welding. It’s clean, fast and creates a strong mechanical bond.

We use liquid nitrogen shrink fitting to fit:

  • Gear wheels to shafts
  • Bearings to housings
  • Sleeves onto pipes
  • Rotors, couplings, and bushes
  • Axles and components within aircraft wheel assemblies

Our professional and experienced team completes jobs quickly and safely with minimal disruption to your operations. We handle time-critical or shutdown projects with expert care.

What Is Shrink Fitting?

Shrink fitting is a precision engineering process used to join metal parts by thermal expansion and contraction.

We cool a component using liquid nitrogen, causing it to shrink. Once inserted into a mating part, it returns to its original size, creating a tight interference fit.

This method is ideal for components requiring exact positioning and reliable, vibration-resistant holding power. It works on gears, bearings, rotors, and sleeves.

We will explain how the process works for your specific application. We also offer support before, during, and after installation.

Our Projects Using Shrink Fitting and Liquid Nitrogen

Our team recently completed two very different but equally critical jobs using liquid nitrogen-based methods.

At a commercial site in Croydon, we delivered shrink fitting services to install install a larger nozzle into an existing Valve. Using liquid nitrogen, we cooled the nozzle before fitting, ensuring a tight, leak-free seal without welding or downtime – learn more, please read our nozzle fitting case study.

In the aviation sector, our engineers used a combination of pipe freezing and shrink fitting techniques during aircraft maintenance. This included isolating hydraulic lines and enabling axle replacement on an aircraft wheel assembly — all without draining or dismantling major systems. Discover more, please read our aircraft maintenance case study.

Both projects show the flexibility, safety, and speed of our shrink fitting with liquid nitrogen and pipe isolation services. We bring this same expertise to every job across London, Kent, Essex, Sussex and Hampshire.
