Thermal Shrinking for Bearings, Shafts & Industrial Assemblies

3mm ​High-density dry ice pellets are an effective and controlled solution for thermal shrinking during precision assembly. By rapidly reducing the temperature of metal components—such as bearings, shafts, bushings, and interference-fit assemblies—dry ice causes the material to contract, allowing parts to slide together smoothly without force.This process helps eliminate the need for presses, excessive heat, or mechanical stress that can damage components or alter tolerances. Once the part returns to ambient temperature, it expands to create a tight, secure fit with excellent alignment and holding strength.Using high-density pellets provides consistent cooling, predictable results, and cleaner handling—making them ideal for maintenance teams, manufacturers, and assembly operations that demand accuracy, repeatability, and reduced risk of component damage.
