As cryogenic applications operate at extreme temperatures, the applications demand the most of all their components, especially bearings. Systems approach absolute zero (0° K), which means it becomes increasingly difficult to utilize liquid lubrications and so specialist substitutes need to be introduced. Standard 52100 steel bearings will provide poor performance in these conditions resulting in a short service life, premature failure, and could even cause initial machine seizure.
In Liquid Natural Gas pumps, cryogenic testing for bearings is conducted by UNASIS’ highly skilled technicians, allowing us to maximize the performance of your cryogenic bearings.

UNASIS manufacturing has decades of experience when it comes to handling low-temperature applications in the cryogenics sector. As members of the British Cryogenic Council, UNASIS employees have deep knowledge and understanding of applications and can utilise our vast resource of information to aid in solving your cryogenic bearings problems.


One common issue with bearing design and selection is clearance control within the bearing assembly. If there is a thermal mismatch between the housing, shaft, and bearing it can essentially eliminate the bearing clearance which renders a bearing useless. Therefore, it is vitally important to collaborate with bearing specialists like UNASIS manufacturing, who have thousands of successful projects that influence our bearing design.
