Basic introduction:
Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without 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 inside the bearing from overflowing.
The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing code is 4. The utility model has the advantages of simple structure and convenient use, and is the most common and widely used type of bearing.
working principle:
Deep groove ball bearings are mainly subjected to radial loads and can also withstand radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed.
Bearing construction:
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. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with snap grooves, and Deep groove ball bearings with large load capacity of ball notches, double row deep groove ball bearings.
Bearing type:
1, single row deep groove ball bearings
2, single row deep groove ball bearing with dust cover
3. Single row deep groove ball bearing with dust cover and sealing ring
4. Single row deep groove ball bearing with stop groove and stop ring on the outer ring
5. Deep groove ball bearing with ball gap
6, double row deep groove ball bearings
According to the size and size of deep groove ball bearings can be divided into:
(1) Miniature bearings----bearings with a nominal outside diameter range of 26mm or less; (2) Small bearings----bearings with a nominal outer diameter range of 28-55mm; (3) Small and medium-sized bearings--- - Bearings with a nominal outer diameter range of 60-115mm; (4) Medium and large bearings----bearings with nominal outer diameters ranging from 120-190mm (5) Large bearings----nominal outer diameters range from 200 -430mm bearings; (6) Extra large bearings----bearings with a nominal outer diameter range of 440mm or more.
