Pressure installation usually uses press, and can also use nuts and bolts. Last resort can be installed using hand hammers, lightly, steady, accurately, and to avoid the severe impact.

Make the bearing expansion after oil heating, and then installed in the shaft, thermal sets installation can avoid unnecessary external force, complete the installation in a short time

1) The general heating should not exceed 100 ° C, heat thoroughly.
2) Does not allow bearings contact the bottom of tank.

Thermal sets installation can also use induction heating device to heat bearings, make the bearing expansion, then installed in the shaft.

Compared with general mechanical parts, the rolling bearings have high precision, so they must be used carefully accordingly.
1) Keep the bearings and the surrounding clean
2) Installation carefully

If there is a strong blow to the bearings because of careless use, bearing will have scars, indentation, fracture and other injuries.
3) Use right tools
4) Pay attention to the anti-rust of the bearings

Avoid the use in moist places; avoid direct contact, people need wearing gloves.
5) The people who make the installation should be familiar with the bearings
6) Make the bearing operating norms or installation process.

Lubricant added 

For bearings, lubrication is an important issue for their performance. Whether Lubricant or lubrication manner is appropriate will greatly affect the life of bearings.
The role of lubrication as follows:
Lubricate bearings parts, reduce friction and wear
Take away the bearings internal heat produced by friction or other reasons,

Make the rolling bearings contact surface regularly form appropriate oil film to extend the fatigue life of bearings
Anti-rust and dust of bearing
Bearing lubrication methods can be broadly divided into grease lubrication and oil lubrication, its general comparison shown in the following table

Grease lubrication compare with the oil lubrication

 

 

Grease lubrication can last a long time without adding grease, and its seal set structure is relatively simple, so it is widely used.
Grease lubrication has the style of pre-filling grease in sealed-bearing, and the style of filling appropriate grease in the internal shell, supplementing or replacing grease from time to time

In addition, for the machines of which there are several mechanical bearings need lubrication, also use the way of centralized lubrication to connect lubrication places by pipelines.

1）The filling of grease

Grease filling amounts vary according to the structure and volume, generally 1/3 to 1/2 of capacity is suitable.
When excessive loading, the grease will be metamorphic because of mixing, aging and softened, and should pay attentation to.
But for low-speed bearings, in order to prevent foreign body penetrating, sometimes fill to the 2/3 to 1of the volume

2)Supplementary and replacement of the grease
The replacement and added of the grease are closely related with the lubrication methods, no matter we chose what way , we must use clean lubricating grease, and pay attentation to avoid the intrusion of external foreign body.
The grease should be added to with the same brand.
When adding grease, it is particularly important to ensure that the new grease into the internal bearing.

Oil lubrication apply to a certain degree of resistance and high temperature, and it can also reduce vibration and noise reducing effective, mostly for fat lubrication NA occasions.

  

Lubricating oil can be divided into:
1) oil bath lubrication
2) oil drop Lubrication

3) splash lubrication
4) cycle lubrication
5) Spray lubrication
6) Oil Mist Lubrication
7) lubricating oil and gas
