Bearing number Identification

Bearing number Identification


    We always call the different types of  bearing number,but actually what does mean it.For example 6001 2RS what does mean it,Lets see.



   6001 2RS

 
Above shows the number of bearing,So lets see 
(6)001 
6 Number shows that the which type of bearing. 6 number for Deep Grove ball bearing.

6(0)01 
0 This number shows the series of bearing which reflect the robustness of bearing.As inner and outer thickness usually increase along with the ball size.

0 Extra light
1 Extra light trust
2 Light
3 Medium
4 Heavy
9 Very thin section

60(01)
The 3rd and 4th bearing number shows the bore size of the bearing.00 to 03 have designated bore size depending on the number.
00 10mm
01 12mm
02 15mm
03 17mm

While the number more than 03 simply have a bore size multiplied with 5 times that of the 3rd and 4th digit.

6001 (2RS)
 
2RS Shows the rubber seal on both sides of bearing.
Only RS shows rubber seal on one side of bearing

2Z or ZZ

2Z or ZZ shows the metal seal on both sides of bearing.

How to control Temperature and Humidity in Air Handling Unit

  How to control Temperature and Humidity in Air Handling Unit Overview Air Handling unit is a system used to supply temperature and Humidity controlled filtered air to the cleanroom. For air filtration various types of filters are used in AHU. And for temperature and Humidity controlling cooling and heating coils are provided in AHU. Goals Control the temperature of air used in the cleanroom  Control the humidity of air used in cleanroom  Air filters Specifications    The air Handling unit consists of Air filter  Cooling coil Heating coil Air blower HEPA Filter  Controlling of Temperature and Humidity  By Cooling Method  The cooling coil recirculates the chilled water having temperatures between 4°C to 6°C. This chilled water comes from the Chiller through centrifugal pumps. When we start the Air Handling unit blowers sucks the air through the pre filters of the air Handling unit. When blowers sucks air, it passes through the cooling co...

AIR FLOW, AIR VELOCITY, ACPH, AHU CAPACITY

Air Changes per Hour AIR VELOCITY AND ACPH OF ROOM OR AREA   Procedure to be followed: Air Velocity Measurement and Calculation of Air Changes: Objective : To demonstrate  that the   air system is balanced and capable of delivering air velocities and providing number of air changes per hour in the respective rooms as   per requirement. Equipment to be used: Hotwire Anemometer or capture Hood Pre Requisite: Air Volumes through supply and return grills and filters should be adjusted as per the design requirement of Air Change Rate and Differential Pressure. Test Method : Ensure that the Supply blower of the AHU is "ON" prior to the start of the observations. For compliance of air change rate, velocity to be measured at 5   different locations to below the each terminal or Grill (Four Corners and center) with the help of calibrated Anemometer. Calculate the   average  velocity of the air coming from Plenum HEPA filter / supply air grill. Calculate the air...

Chiller Approach Temperature

 Chiller Approach Chiller Approach is a essential check point for ensuring that the chiller is a running at peak efficiency.When the chiller condenser approach temperature is within operating range,it indicate the condenser tubes are clean and chiller runs efficient.When increased approach temperature reduces the efficiency and it need maintenance. What is Approach Temperature? Chiller Approach temperature is the temperature difference between the liquid refrigerant temperature that leaving the condenser and the leaving cooling water temperature.This temperature difference is called chiller approach temperature. Effects of Approach Temperature:- If the  Condenser approach temperature is within the operating range that indicate the condenser coils are in good condition and cleaned.In this condition chiller runs efficiently. If the condenser approach temperature is out of the operating range that indicate the condenser coil scaled from inner side due to which heat transfer not d...
