High Precision Deep Groove Ball Bearings Corrosion Resistant Long Life
628ZZ deep groove ball bearing hand drill drill polishing machine angle grinder special bearing
1. Deep groove ball bearings generally consist of a pair of rings, a set of cages, and a set of steel balls.
2. Its simple structure and easy to use make it the most common and widely used type of bearing.
3. This type of bearing is mainly used to bear radial load, but it can also bear a certain amount of axial load in any direction.
4. When the radial oil gap of the bearing is increased within a certain range, this bearing has the properties of an angular contact ball bearing and can also bear a large axial load.
5. After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the housing can be limited to the axial range of the bearing.
6. At the same time, when the housing hole and the shaft (or the outer ring to the inner ring) are relatively inclined, (no more than 8ˊ-16ˊ, determined according to the clearance), it can still work normally. Since there is a tilt, the bearing life must be reduced.
7. Used in the fields of textiles; mining; automotive; machine tools and other fields.

Outer spherical bearing with housing is divided into bearing core and bearing housing
1. Spherical spherical bearing is a bearing unit that combines rolling bearing and bearing housing.
2. Most outer spherical bearings have a spherical outer diameter and are mounted together with a bearing housing with a spherical inner hole.
3. The structure is diverse, versatile and interchangeable.
4. At the same time, this type of bearing also has a certain self-aligning design, easy to install, and has a double structure sealing device, which can work in harsh environments.
5. The bearing housing is generally formed by casting. Commonly used seats are vertical seat (P), square seat (F), convex square seat (FS), convex round seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. ( T).

The outer spherical bearing with a seat is divided into a bearing core and a bearing seat.
It is called by the bearing core plus the bearing seat in the name, such as the outer spherical bearing with set screw UC205 and the vertical seat is called UCP205.
Due to its strong interchangeability, the bearing core can be freely assembled in bearing housings of the same specification and different shapes.
