Deep groove ball bearings are composed of an outer ring, an inner ring, a group of steel balls and a group of cages.
Deep groove ball bearings are the most commonly used rolling bearings.
Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear the combined diameter and axial load. When the speed is higher and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. This kind of bearing has small friction coefficient and high limit speed. But not impact resistant, not suitable for heavy load.
FAQ
1What is the meaning of bearing DN value?
Sliding line speed limit DN value [product of bearing inner diameter (mm) and shaft speed (r/min)], foreign studies have been completed on the 6 power bearing DN value is 3.0×10, the present condition of our country is 2.5 to 3.0×10 6 power research goal, there is a certain gap.
2How to know its diameter by bearing type?
Generally, the nominal inner diameter of bearings can be known from the bearing type, but the outer diameter and width dimensions should be checked for relevant information. The relationship between the nominal inner diameter and the code name of the bearing is:
1) The inner diameter is 0.6 ~ 10 (non-integer), and the code is directly expressed by the nominal inner diameter in millimeters, such as the deep groove ball bearing 618/2.5, that is, D =2.5;
2) The inner diameter 10 ~ 17 has special code, and the code of inner diameter 10, 12, 15 and 17 are 00, 01, 02 and 03 respectively. For example, 6201, d=12;
3) The inner diameter ranges from 20 to 480, which is the quotient of dividing the inner diameter by 5. If the quotient is less than two digits, add "0", such as 08. For example, 23208, d=40;
4) If the inner diameter is greater than or equal to 500 or above and 22, 28, 32, it is directly expressed by the number of inner diameter in millimeters, and is separated by "/" between size series, similar to 1). If 230/500, d=500; 63/28, so d is equal to 28.
3What does SKF bearing 6200-2RS2/C3GHH mean?
Bearing type and rear code description is as follows:
6200: Basic model (deep groove ball bearing, size 10×30×9).
2RS2: Contact seal with fluorinated rubber ring lined with steel plate on both sides (Note: 2RS1 is contact seal with vulcanized rubber ring lined with steel plate on both sides).
/C3: clearance meets the standard of 3 groups, clearance is greater than 0 group.
GHH: G-- grease injection (i.e., grease lubrication); H (immediately after G) - high temperature grease, operating temperature range -20 ~ 130℃; H (last bit) -- the grease actually used is high temperature oil, and the upper limit of temperature is > 130℃.
4Are 6311 bearings and 6411 bearings the same size?
The inner diameter and outer diameter are the same. The size of steel ball 6411 is larger than that of 6311, and the height is a little higher.
Applications: small gasoline generator, motor, contact plate, solenoid valve, thread grinder, heat transfer equipment, electric belt, vertical sawing machine, gas turbine, vehicle lights and other equipment.
