Bearings are in the process of mechanical transmission fixed and reduce the load coefficient of friction components. Can also say that when the other parts in the shaft relative motion, used to reduce friction during power transmission coefficient and holding shaft center position fixed parts. Bearings are one kind of modern machinery and equipment vital components.

Steel is installed on the bottom of the hinge a number of similar components.
Retractable roof comprises a total of nine ball bearing manufacturer plate is divided into two parts: one is 4 , and the other part of the 5 . On either side of each plate are fixed with angled steel . There are 10 frames across 77 meters of the stadium . Each steel wheels supported by a set of ports can be installed in the center court along both sides of the track move . Ready to close the retractable roof , the northernmost part of the stadium to keep the folded state , parked in another part of the southern end . To ensure the accuracy of the roof moves , you need to install a high-precision electronic actuators, servo motor and rocker synthesis system . This system will separate the steel , while steel Slim bearing the upper and the steel parts of substantially begin until the two parts of the top center of the pitch joints combined stacked flat . Steel is installed on the bottom of the hinge a number of similar components. Schaeffler FAG spherical roller bearings assembled in these hinge . These bearings due to friction is small, and can be carried out right kind of compensation is selected. These bearings are grease lubricated through high-performance , during use, requires minimal maintenance
