Deep groove ball is divided into two types: sealed and open. The open type means that the bearing does not have a sealing structure. The sealed deep groove ball is divided into dustproof seal and oil proof. seal. The dust seal cover material is stamped from steel plate, which is simple to prevent dust from entering the bearing raceway. The oil-proof type is a contact type oil seal, which can effectively prevent the grease from overflowing inside the bearing.

And according to bearing size, there are many types deep groove ball bearing too:
(1) Miniature bearings---bearings with a nominal outside diameter less than 26 mm
(2) Small bearings--bearings with outer diameter between 28-55mm;
(3) Small and medium-sized bearings bearings with outer diameter between 60-115mm;
(4) Medium and large bearings----bearings with outer diameter between 120-190mm
(5) Large bearings---bearings with outer diameter between 200-430mm;
(6) Extra large bearings--bearings with outer diameter between 440mm or more.

The deep groove ball bearing,  has a simple structure and is easy to achieve high manufacturing precision compared with other types, so it is easy to be mass-produced in series, and the manufacturing cost is also low, and the use is extremely common. Ball bearing can be used in gearbox, instrument, electric motor, home appliance, internal combustion engine, traffic vehicle, agricultural machinery, construction machinery, engineering machinery, etc.
