One. Bearing:
(1) Rolling bearing general theory 1. Rolling bearing
a bearing that tumbling between a load-bearing and mutually moving part; it contains race parts and a roll set with or without a barrier or guide. Can be used to accept radial, axial or radial and axial Combined load.
2. Single row bearing
Rolling bearing with a row of rolling elements.
3. Double row bearing
Rolling bearing with two rows of tumblers.
4. Multi-row bearing
Roller bearing with more than two rows; rolling bearings bearing the same direction of load; the best is to indicate the number of columns and bearing type; for example: "four-row radial cylindrical roller bearing".
5. Full complement rolling bearing
Bearings without cages; the total gap between the circumferential directions of each row of rolling elements is smaller than the diameter of the rolling body and as much as possible.
6. Angular touch bearing angular contact bearing
Rolling bearings with a nominal touch angle greater than 0° and less than 90°.
7. Self-aligning bearing
A raceway is spherical; a bearing that can get used to the angular error and angular motion between the two raceways.
8. Separable bearing
Rolling bearings with separate parts.
9. Not to leave the bearing non-separable bearing
After the end of the device; the bearing ring can not be arbitrarily separated from the rolling bearing.
Note: For bearings that do not leave the part differently; for example, ball bearings with double half rings (02, 01, 08) are not subject to regular abbreviations.
10. Inch bearing inch bearing
The original design dimensions and the rolling bearings indicated in English units.
11. Open bearing
Rolling bearing without dust cover and sealing ring.
12. Sealed bearing
Rolling bearing with sealing ring on one or both sides.
13. Dust cover bearing shielded bearing
Rolling bearing with dust cover on one or both sides.
14. Closed bearing
With one or two sealing rings; one or two dust caps and a sealing ring and a dust cover rolling bearing.
15. Pre-smooth bearing
The manufacturer is now filled with smoothing roller bearings.
16. Instrument fine bearing instrument
Instrument-specific rolling bearings.
17. Combination bearing
Paired into a pair or a set of rolling bearings.
. Noisy å²¢ 1. Radial bearing
It is primarily used for rolling bearings that accept radial loads; its nominal touch angle is between 0° and 45°; the fundamental parts are the inner ring, the outer ring and the roll with or without the cage.
2. Radial contact bearing
A centripetal rolling bearing with a nominal touch angle of 0°.
3. Angular contact radial bearing
A centripetal rolling bearing with a nominal touch angle greater than 0° to 45°.
4. Spherical bearing
Radial rolling bearing with outer spherical surface and wide inner ring with locking parts. It is mainly used for simple outer casing.
5. Tapered bore bearing
A centripetal rolling bearing with a tapered bore in the inner ring.
6. Flanged bearing
On one of its ferrules; usually a radial roller bearing with an outer radial flange on the outer ring or conical outer ring.
7. Roller bearing (rolling bearing)
a radial rolling bearing with a thick section outer ring; as a wheel tumbling on a rail; for example a cam track.
8. Retaining ring type roller (rolling) bearing yoke type track roller (rolling bearing)
Roller bearing with a pair of flat retaining rings.
9. Universal matching bearing
When you choose one or more sets of the same type of centripetal rolling bearings, you can get the characteristics of the paired or grouped devices.

Definition of Plant Extracts:

Plant extracts are substances that are extracted or processed from plants (all or a part of the plant) in the pharmaceutical industry, the food industry, the health industry, the beauty industry, and other industries using appropriate solvents or methods.

The plant extract is a plant-based material that, according to the need for the intended use of the extracted final product, undergoes a physical and chemical extraction separation process that directs and concentrates one or more of the active ingredients in the plant without altering its active ingredient Structure and the formation of the product.
