Place the entire bearing into the low-temperature chamber and cool it down to -120℃ to -180℃. As the metal bearing cools, it shrinks and its inner and outer diameters become smaller. Thus, it can be easily installed onto the shaft/bearing housing. After returning to room temperature, the bearing expands, forming a tight interference fit.
Five key benefits of the bearing itself:
1. Damage-free installation, preserving bearing accuracy
2. Avoid high temperatures that could damage bearing grease and heat treatment properties
Cold mounting is performed at low temperatures throughout the process, ensuring no impact on the bearing's metallography, quenching hardness, or original lubrication.
3. Uniform coordination and stable force distribution
4. Compatible with high-precision bearings
Cold fitting meets micrometer-level assembly requirements, ensuring dynamic balance.
5. High assembly efficiency, suitable for mass production ,Assembly can be completed within minutes of cooling
