Deep Groove Ball Bearings, Deep Groove Ball Bearings) is the most common rolling bearing a type. Prototype deep groove ball bearing by a case and an inner ring, a group of steel ball and a set of cage structure, deep groove ball bearing type code is 6.
Deep groove ball bearing is mainly used for under pure radial load, also can also bear radial load and axial load. When the only subject to pure radial load, the contact Angle is zero. When deep groove ball bearing with large radial clearance, the angular contact bearing performance, can bear the larger axial load. Deep groove ball bearing friction coefficient is very small, limit speed is high, especially in the axial load a lot of high-speed operation conditions, deep groove ball bearing ratio thrust ball bearing is more superiority.
