Permanent magnet bearings are transforming sectors like turbomachinery, pumps, motors, generators, and flywheel energy storage systems. Offering benefits such as non-contact operation, low maintenance, and lubrication-free performance, permanent magnet bearings show advantages over traditional mechanical bearings.
SmCo and NdFeB magnets are commonly used in permanent magnet bearings for their ability to generate a strong magnetic field suitable for applications requiring magnetic support and levitation. Especially, for applications demanding high reliability at operating temperatures above 200°C, SmCo magnets are the go-to choice.
When it comes to shapes, round and ring magnets are predominantly used in permanent magnet bearings.
