The most commonly used bearings are Deep-Groove Ball Bearings. Thanks to their simple design, they are easy to maintain and not as sensitive to operating conditions thus are used in a wide range of different applicaitons.
In addition to radial forces, they absorb axial forces in both directions. Their low torque also makes them suitable for high speed.
1、Basic parameters
Deep groove ball bearings are one of the most common types of rolling bearings.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. Deep groove ball bearing type has single row and double row two, deep groove ball structure is also divided into sealed and open two kinds of structure, open refers to the bearing without sealing structure, sealed deep groove ball is divided into dustproof seal and oilproof seal. Dustproof seal cover material for steel plate stamping, only play a simple prevent dust into the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease inside the bearing from spilling out.
Single row deep groove ball bearing type code for 6, double row deep groove ball bearing code for 4. Its structure is simple, easy to use, is the most common production, the most widely used type of bearings.
2、Structure and Types
Bearing structure
Deep groove ball bearing structure is simple, compared with other types of easy to achieve high manufacturing accuracy, so it is easy to series mass production, manufacturing costs are also lower, the use of extremely common. In addition to the basic type of deep groove ball bearings, there are various variants of structure, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seal, deep groove ball bearings with stop groove, deep groove ball bearings with large load capacity with ball loading gap, double row deep groove ball bearings.
Bearing Types
Deep groove ball bearing is mainly used to bear radial load, but also commonly used to bear radial and axial combined load. Especially the mechanical equipment speed is very high, should not use thrust bearing, the bearing can be used to bear two-way pure axial load, and no maintenance during the work, is a lower price, a wide range of bearings. Deep groove ball bearing models are: deep groove ball bearings (60000 type); deep groove ball bearings with outer ring stop groove (60000N type); deep groove ball bearings with dust cover on one side and stop groove on the other side (60000-ZN type); deep groove ball bearings with dust cover on both sides and stop groove on the outer ring (60000-2ZN type); deep groove ball bearings with dust cover on one side ( 60000Z type); deep groove ball bearings with dust cover on both sides (60000-2Z type); deep groove ball bearings with seal on one side (60000-LS type, 60000-RZ type); deep groove ball bearings with seal on both sides (60000-2LS type, 60000-2RZ type); deep groove ball bearings with flange outer ring (F60000 type); deep groove ball bearings with dust cover on one side deep groove ball bearing with dust cover on one side (F60000-Z type); deep groove ball bearing with dust cover on both sides (F60000-2Z type), a total of 11 types of deep groove ball bearing.
According to the size dimensions of deep groove ball bearings can be divided into.
(1) Miniature bearings ---- with nominal outer diameter size range of 26mm or less;
(2) Small bearings ---- with nominal outside diameter size range of 28-55mm;
(3) Small and medium-sized bearings ---- with nominal outer diameter size range of 60-115mm;
(4) Medium and large size bearings ---- with nominal outer diameter size range of 120-190mm
(5) Large size bearings ---- with nominal outer diameter size range of 200-430mm;
(6) Extra large bearings ---- with nominal outer diameter size range of 440mm or more.
Applications
Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yoyos, etc.
