introduction：Deep groove ball bearing imported bearings are mainly used to withstand pure radial load，It can also withstand both radial and axial loads。When it is subjected to pure radial load only，The contact Angle is zero。When the deep groove ball bearing has a large radial clearance，Angular contact bearing performance，Can withstand large axial loads 。The friction coefficient of deep groove ball bearing is very small，The limit speed is also very high， Especially under high speed operating conditions with large axial loads，Deep groove ball bearings have more advantages than thrust ball bearings。

introduction：Linear bearing is a linear motion system，Used in combination with linear travel and cylindrical shaft。Due to the bearing ball contact with the bearing jacket point，The steel ball rolls with little friction resistance，Therefore, linear bearings have low friction，And relatively stable，Does not vary with bearing speed，Can obtain high sensitivity、Smooth linear motion with high accuracy。
