ball Deep Groove Ball Bearing 10x30x9

Deep groove ball bearing (gb/t 276-2003), formerly known as single row radial ball bearing, is the most widely used rolling bearing. It is characterized by low friction resistance and high speed. It can be used for mechanical parts that bear radial load or combined radial and axial load at the same time. It can also be used for mechanical parts that bear axial load, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

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.

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.

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
