Desiccants for Absorption air dryer

Activated alumina/Desiccant beads have a white, spherical, non-toxic, odorless, insoluble in water and alcohol. They are able to stand out thermal shock and abrasion with highly mechanical stability and strong absorption (impervious). The particle shape does not expand or crack after absorbing.
Air compressor oil uses

Air compressor oil uses

The movement of screw is pineaple-sharpened, therefore it's nescessary to use lubricating oil with theaim to reduce the corrosion and softly operate. The bearing is completely stay in air end so it is also lubricated with air compressor oil.

How to read bearing parameters

Wednesday - 02/01/2019 04:02

When using the bearing, we see the parrameter. The information on the bearing is a range of letters and number which shows information of; type of bearing, dimensions, accuracy, and other parameters  etc. So, How to understand the parameters correctly, this articale may be useful: 

vong bi 2,bearing parameters
Bearing

1.According to  TCVN 3776-83 the bearing parameter will be understood as following: 

- Ball bearing is abbriviated by numbers. Two last numbers show the inner diameter from 20 to 495 mm, these number is as 1/5  as the real dimensions. The number has inner diameter from 10 to 20 mm signed 00 (10mm), 01 (12mm), 02 (15mm), 03 (15mm), 03 (17mm).
For example: The number 150212 on the bearing mean: 1 range bearing  (0), outer ring (5), light load (2), width (1), inner diameter 60 mm (12×5).
- Other examples:

2. Meaning of load :

- The third number from right to left. 

1 or 7

Very light load 

2

 Light load only

3

Medium load only 

4

Heavy load only

5

Very heavy load only

6

Medium load same as 3 but it's thicker 

8-9

Really load only; 814, 820, 914

 3. Meaning of classification:

 The 4th number from right to left indecates the bearing 0-9.    

0

The 1 layer ball bearing 

1

The 2 layer ball bearing 

2

1 layer short cylindrical roller  bearing 

3

2 layer short cylindrical roller  bearing 

4

1 layer long cylindrical rollerbearing 

5

Twisted cylindrical bearing 

6

Thrust ball bearing 

7

Tapered roller bearing 

8

Not radial thrust ball bearing

9

Cylindrical roller thrust bearings

4. Structural meaning :

 The number from right to left.  

3

1 row  cylindrical roller thrust bearing, burrless inner thrust ring without 

4

The same as 3  with barrier ring

5

1 groove baking in the outter ring 

6

1 basket stoping oil made of steel sheet

9

 1 row short thrust  cylindrical roller bearing, there is a ring thrusting the ballroller. 

 
For example:
  Read the 60304 bearing paramaters.
-          ID 04x5 = 20mm
-          Load: Medium

-          1 layer ball bearing 
-          1 basket stoping oil made of steel sheet
Note : If there is 3 last number , the last number is ID (D<20mm).
        Ex : 678 , d=8mm, light load, thrust ball bearing 

5. Bearing gap:
