Where can you buy ball bearings?How to select ball bearing?

The following factors are mainly considered when choosing:
1. Bearing load
The size, direction, and nature of the load on the bearing is the primary basis for selecting the type of bearing.
(1) Load size and nature Ball bearings should be used for light and medium loads; roller bearings should be used for heavy loads or impact loads.
(2) Load direction
For radial loads, deep groove ball bearings, cylindrical roller bearings or needle roller bearings can be used. When pure axial load, thrust bearings can be used. That is, when there is radial load and axial load, if the axial load is not too large, deep groove ball bearings or angular contact ball bearings or tapered roller bearings with smaller contact angles can be selected; if the axial load is large, The two types of bearings with larger contact angles can be selected; if the axial load is large and the radial load is small, the thrust angular contact bearings can be used, and the radial bearing and the thrust bearing together can also be used as the support structure.

2. Bearing speed
(1) Ball bearings should be preferred when high speeds are used;
(2) When the inner diameter is the same, the smaller the outer diameter, the smaller the centrifugal force. Therefore, in the high-speed, we should choose ultra-light, special light series of bearings.
(3) The limit rotational speed of thrust bearings is very low, and the frictional heat is severe during high-speed operation. If the axial load is not very large, angular contact ball bearings or deep groove ball bearings can be used to withstand pure axial forces.

3. Alignment requirements
When the axis of the shaft does not coincide with the centerline of the bearing due to factors such as manufacturing and installation errors, when aligning the axis of the inner and outer rings of the bearing due to force bending, aligning ball bearings or self-aligning roller bearings should be used.

4. Allowed space
When the radial space is limited, a needle roller bearing or special light and ultra-light diameter series bearings can be selected. When the axial dimension is limited, bearings with a small width, such as a narrow or very narrow width series, can be selected.

5. Installation and disassembly
In the bearing housing is not divided and must be installed and dismantled along the axial direction of the bearing and the need for frequent installation and removal of the bearing machinery, should be preferred inner and outer ring detachable bearings (such as 3 categories, N, etc.); when the bearing is in the long axis When mounting, a bearing with a conical hole in the inner ring (post-code number 2 is K) can be selected for easy assembly and disassembly.

6. Tolerance level
Dynamic bearing tolerances are divided into 6 levels: 0 (ordinary), 6, 6X, 5, 4 and 2. Ordinary level is the lowest, and level 2 is the highest. Ordinary level is the most widely used. For most machines, a bearing with a tolerance of 0 is sufficient, but high-precision bearings should be used for machine spindles, precision machinery, instruments, and high-speed rotating shafts that require strict rotational accuracy.

7. Price
Different types of bearings, the price is different, the lowest price of deep groove ball bearings, roller bearings higher than the price of ball bearings, angular contact bearings than the high price of radial contact bearings. The higher the tolerance level, the more expensive the price. In the premise of meeting the requirements of use, inexpensive bearings should be used as far as possible.
