In accordance with the sizes of deep groove ball bearings can be divided into:
(1) miniature bearings ---- nominal diameter size range of 26mm bearings;
(2) small bearing ---- nominal diameter size range of 28-55mm bearings;
(3) small and medium-sized bearings ---- nominal diameter size range of 60-115mm bearings;
(4) large bearing ---- nominal diameter size range of 120-190mm bearings
(5) large bearing ---- nominal diameter size range of 200-430mm bearings;
(6) ---- large bearing diameter size range of 440mm or more beari
Method of extending the bearing’s lifetime
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2. Don't allow strong impact, such as hammer striking, transfer roller pressure
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
7. Bearing should not be ultra cooled.
|Single-Row Deep Groove Ball Bearings|
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.
|Extra Small Ball Bearings and Miniature Ball Bearings|
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:
|Maximum-Type Ball Bearings|
|Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.|
|The inner groove of magneto bearings is a little shallower than that of deep groove bearings. Since the outer ring has a shoulder on only one side, the outer ring may be removed. This is often advantageous for mounting. In general, two such bearings are used in duplex pairs. Magneto bearings are small bearings with a bore diameter of 4 to 20 mm and are mainly used for small magnetos, gyroscopes, instruments, etc. Pressed brass cages are generally used.|
