1.Brief description of deep groove ball bearing

Deep groove ball bearing is the most common type among ball bearings.The basic structure of deep groove ball bearing include an outer ring,an inner ring, a group of steel ball and a set of cage. Deep groove ball bearing has two types: single row and double rows bearings. The simple structure,convenience,and large production contribute deep groove ball bearing to be the most widely used kind. Deep goove ball bearing is nonseperatable and the design is very simple. This kind of bearing don't need special maintainance

 · Single Row Deep Groove Ball Bearings: Single row deep groove ball bearings are the most commonly used bearing type, which can accommodate radial and thrust loads. These bearings can be used at high speeds. The self-aligning capacity of deep groove ball bearings is limited; therefore the bearing locations must be accurately aligned. 

· Double Row Deep Groove Ball Bearings Double row deep groove ball bearings have, contrary to their former design, no filling slots. This is the reason that these bearings can accommodate thrust loads in both directions. These are fitted with cages of glass-fibre reinforced polyamide 66 and lubricated with grease. This ball bearing is not suitable, where angular misalignments have to be accommodated
