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:
Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
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. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 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.
Horizontal lathe milling machine transformation
The existence of waste machine tools in various manufacturers has certain universality. Our company has a number of long-term waste horizontal lathes. After milling and transformation, it has also shown new vitality. The following are introduced: (1) Processing objects are shown in Figure 1. Requires the removal of the riser system to ensure the size of the pattern. (2) Reconstruction measures The partial map of the transformation system is shown in Figure 2. Remove the three-jaw self-centering chuck, insert the mandrel 1 into the taper hole of the machine spindle, and use
