3. Good wear resistance 
4. Good dimensional stability 
5. Good toughness against impact load 

2RS double-sided rubber seal cover

1. oil resistance 

2. wear resistance 

3.Good heat resistance 

OEM is welcome.We can customize according to customers' requirements.

Deep groove ball bearings have the characteristics of low frictional resistance and high rotation speed.
It can be used on machine parts which could withstand radial load or combined load of radial and axial simultaneous action. Can also be used on machine parts which bearing axial load.

The deep groove ball bearings are widely used in gearboxes, instrumentation, motors, power tools, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller pulley shoes, Yo-Yo and so on. 

With the rapid development of industrial and mechanical automation, deep groove ball bearings are becoming more and more widely used. 

Due to featues of simple structure, convenient use and widely appliction , deep groove ball bearings have won the favor of many manufacturers and consumers.

Step 1: Known the operating conditions of the bearing

1. Main functions and structures of the machine : for example, motor-spindle, conveying speed and torque.
2. Mounting position of bearing
3. The bearing need bear the size, direction, nature, and if need impact load or not.
4. Lubrication condition of bearing.
5. Environmental conditions around the bearing. Such as: corrosion, cleanliness, humidity, environmental temperature, heat dissipation, etc.
6. Working speed and temperature of the bearing.

Step 2: bearing structure selection

1. Dimension space;
2. Bearing capacity, including size, direction and nature
3. Limit speed;
4. Rigid
5. Tolerance grade;
6. Tuning performance
7. Installation and disassembly requirements;
8. Price and availability;
9. Supporting form.

Step 3: bearing size selection

1. Service life and reliability requirements;
2. Basic rated dynamic (static) load;
3. Bearing size;
4. Limit speed;
5. Allowable axial bearing capacity (for radial bearing).
6. Safety factor;
7. Size space.

Step 4: bearing accuracy selection

1. Function and structure of the main machine: it belongs to precision machinery such as machine tools or common equipment
2. Accuracy of shaft and housing; 
3. Friction torque
4. Rotation speed;
5. Vibration and noise;
6. Stiffness Clearance

Step 5: bearing clearance selection

1.Structure and material of shaft and shell;
2.coordinate
3. Environmental temperature and working temperature of the bearing;
4. Working speed of bearing;
5. The load required by the bearing;
6. Allowable deviation of the ring.

Step 6: Cage structure selection

1. Working speed of bearing;
2. Vibration and noise
3. The nature of the load: whether the impact load;
4. Lubricant and lubrication mode;
5. Guide mode of cage.

Step 7: lubrication selection

1. Working speed of bearing;
2. Bearing load and properties;
3. Lubrication mode;
4. Sealing method.

Step 8: selection of installation and disassembly

1. Cooperation;
2. Installation and disassembly methods.
