Choosing the right size air bearing for your application is important to ensure that it performs appropriately and meets the requirements of your application. Here are a few factors to consider when selecting the size of an air bearing: Load-bearing capacity: The load-bearing capacity of an air bearing is determined by the pressure of the gas film and the size of the bearing surfaces. It is important to ensure that the air bearing is capable of supporting the required load without failing or deforming. Envelope Size Accuracy Operating conditions: The operating conditions of the air bearing, such as temperature, humidity, and contamination, can also affect its performance. It is important to consider these factors and choose a size that is appropriate for the operating environment.
