Overview of Air Bearings and Design Configurations

Overview of Air Bearings and Design Configurations Richard Pultar OPTI521 Deceer 14, 2016 Introduction Air bearings are a type of bearing that use pressurized air to create an air gap between two surfaces. As a result, the bearing surfaces do not contact which eliminates many problems associated with traditional bearings.

Inner Wheel Bearing Recommendation for a Nuer 84 Spindle

The inner and outer bearing surfaces on a nuer 84 spindle are different diameters. The outer bearing will ride on a 1.00 inch diameter surface and the inner bearing will ride on a 1.378 inch surface. It sounds like you have the correct outer bearing and now are in need of the correct inner bearing. For that you would want the part # L68149
