A four-point contact ball bearing makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads because it can handle all three simultaneously. They are primarily used for slow to moderate-speed applications, or where oscillatory movement is predominant. Read More

A static load bearing is the weight applied without any build up of energy, and therefore is to remain motionless. Force, pressure, and gravity remain static or are applied gradually. A dynamic load bearing is measured by the application of rapid force or pressure to an object.In static loading all Read More
