Kinds of bearings for Motorcycles, Electric Bicycles, Electric Motors (Scooters), Electric Tools, Fans, Sports Apparatus, Washing Machines, Dust Collectors, Ventilators, Textile Machines, Running Machines (Treadmills), Household Appliances, Water Pumps, Agricultural Machines, Precision Machineries, etc.

 

First, the concept of deep groove ball bearings
Each ring has a cross-sectional circumference of the ball about one-third of the continuous groove type raceway radial ball bearings for precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc., for the machinery industry the most widely used class of bearings. Simple structure, easy maintenance. Mainly used to bear radial load, but also bear certain axial load, when the bearing radial clearance increased, with angular contact ball bearing performance, can bear large axial load. This kind of bearing friction coefficient is small, extreme high speed, size range and diverse. Solid and durable, versatile and low noise operation, can operate at high speed and ease of installation. Single row deep groove ball bearings otherwise seal design, can no longer lubrication and no maintenance. Single row with filling gaps and double row ball bearings for heavy working conditions.

Second, bearing Caution
Compared with the general machinery parts, high precision rolling bearings, therefore accordingly should be careful when using.
1) Keep clean the bearing and its surrounding
2) When using carefully: careless to bearing a strong impact, it will appear bearing scars, indentation, fracture and other injuries if using.
3) Use the right tools
4) Note bearing rust: Avoid damp places, but also not to sweat stained, should wear gloves.
5) Users should be familiar with the bearing
6) Develop a job specification bearings used

b, and the periphery of the bearing cleaning
c, install parts of the size and processing quality inspection
d, the mounting operation
Check e, after the installation
f, demolition work
g, maintenance (periodic inspection)
h, supplemental lubricant

Third, bearing custody
Bearing at the factory are coated with an appropriate amount of anti-rust oil and rust-proof paper packaging, as long as the packaging is not damaged, the quality will be guaranteed. But long-term storage, to be less than 65% humidity and a temperature of about 20 ℃ under the conditions, and stored on a shelf above the ground 30cm appropriate. In addition, the storage places should avoid direct sunlight or contact with cold walls.

Fourth, bearing maintenance
In order to give full play to the bearing and long-term to maintain its proper performance, we must effectively do regular maintenance (periodic inspection). Through appropriate periodic inspection, so that early detection of failures, prevent accidents in the first place, to improve productivity and economy is very important. 1, cleaning
The bearings removed for inspection, the first good appearance record with photography and other methods. In addition, to confirm the remaining amount of lubricant and lubricant sampling, and then cleaning bearings.
a, bearing coarse washing and cleaning points for sperm washing, and placed in the bottom of the container using a metal grid.
b, coarse wash, brush with oil or grease and other clear adhesive material. In this case, if the rotation in the oil bearing, note damage due to foreign body rolling surface.
c, sperm washing, in the oil slowly rotating bearings should be carefully carried.
Cleaning agent used is generally neutral water-free diesel or kerosene, is sometimes necessary to use warm lye. No matter what kind of cleaning agent used, filter should always be kept clean.
After cleaning, immediately bearing coated anti-rust oil or antirust grease.
2, inspection and judgment
In order to determine whether the removed bearing re-use, to focus on checking the accuracy of its size, rotation accuracy, internal clearance and with the surface, raceway, cage and ring.
On the test results, it can be judged with a bearing or bearings are proficient.
Judgment criteria based on mechanical properties and degree of importance and inspection cycles vary. If the following injury, the bearings must not be reused and must be replaced.
1) fracture and defect bearing components.
2) rolling surface raceway was peeling.


Bearing at the factory are coated with an appropriate amount of anti-rust oil and plastic drums, as long as the packaging is not damaged, the quality will be guaranteed. But long-term storage, to be less than 65% humidity and a temperature of about 20 ℃ under the conditions, and stored on a shelf above the ground 30cm appropriate. In addition, the storage places should avoid direct sunlight or contact with cold walls.

 

Material

Bearing consists of inner and outer ring and cage, dust cover/sealing ring and ball four. NIN bearing ring and ball using refined bearing steel GCr15 (AISI 52100) manufacturing, cage using brass (H62) or high quality cold rolled steel ((SPCC) BQB402) stamping made, if necessary can be used to enhance engineering plastics manufacturing, dust cover adopts imported special material (SP CCJISG314) or stainless steel belt (1 cr18ni9) made of nitrile oil resistant rubber sealing ring by phosphating steel skeleton and hot pressing.
Bearing steel, stainless steel chemical composition as shown in the table below:
