As one of the hard to find large ball bearings, NSK 68/500 bearings are well appreciated by abroad and domestic customers, including Singapore, Indonesia, Colombia, South Africa, United States, Egypt, Iran, Brazil, Mexico, Spain, etc. Static equivalent load refers to pure radial or axial load that provides the same amount of permanent set as the maximum permanent set produced in the contact surface of the rolling elements and raceway when receiving the maximum load under actual load conditions. This is used for bearing selection under load conditions where the bearing is stationary or turns at extremely low speed.
