16004 zz Deep Groove Ball Bearing

Small and micro ball bearings
Miniature and instrument ball bearings are divided into two basic types: deep groove ball bearings and angular contact ball bearings. Deep groove ball bearings can be further divided into the following five types according to the detailed design: standard type, flanged outer ring type, wide inner ring type, and expanded type whose outer ring or inner ring radial thickness is much larger than that of ordinary bearings. , The inner and outer rings are both very thin in the radial direction. Deep groove ball bearings can also be divided into “open type”, “dust cover type” and “sealed ring type” according to the form of sealing or dust prevention.

We have a wide variety of deep groove ball bearings. Deep groove ball bearing is also the most common type of bearing, but it is widely used in many fields.

Characteristics of deep groove ball bearing:

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 certain performance of angular contact ball bearing and can bear the combined radial and axial load. When the rotating speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size of deep groove ball bearings, this kind of bearing has small friction coefficient and high limit speed. But it is not resistant to impact and is not suitable to bear heavy loads.

After the deep groove ball bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance of the bearing, so it can be positioned axially in both directions. In addition, this kind of bearing also has a certain centering ability. When it is inclined by 2 ′～ 10 ′ relative to the shell hole, it can still work normally, but it has a certain impact on the service life of the bearing

Processing form

The processing form of deep groove ball bearing parts is as follows:

1. Multi process processing: generally, bearing production requires 20 ~ 40 processes, with more than 70 processes.
2. Forming processing: the working surfaces of bearing parts are all rotary forming surfaces, which are suitable for processing by forming method.
3. Precision machining: most surfaces of bearing parts need to be ground, and the grinding dimension and geometric accuracy are based on μ M is the unit.

According to the size of deep groove ball bearings, they can be divided into:

Miniature bearing —- bearing with nominal outer diameter less than 26mm;
Small bearings —- bearings with a nominal outer diameter of 28-55mm;
Small and medium-sized bearings —- bearings with a nominal outer diameter of 60-115mm;
Medium and large bearings —- bearings with nominal outer diameter ranging from 120 to 190mm
Large bearing —- bearing with nominal outer diameter ranging from 200 to 430mm;
Oversize bearing —- bearing with a nominal outer diameter of more than 440mm.

Deep groove ball bearing Application

Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yos, etc
