Air End Repair -AC - 03/Sept/2009

Common Air End Failure and Repair

WHY ?

Its Bearings need to replace regularly ?

The bearings are to hold both the rotors in horizontal position;

they are not to rub against each others.

A failed Rotary Screw Air Compressor's Air End:= Atlas Copco GA132, we dismantle on Thursday, 3rd September, 2009 from a factory in Prai Industrial, Penang.

Four Point Ball bearing position and set clearances of rotors end cover clearances !!!!!

  

  Air End Bearings:= 

 Types and size of bearings: 

QJ 315 = 2 sets 

NU 315 ECJ/C3 = 4 sets 

 Note:= 

There are three types of bearing cage to choose from, there are NU 315 ECJ = Steel cage 

NU 315 ECP = Polyamide cage [ a type of plastic material ] 

NU 315 ECM = Brass cage

Rotary Twin Screw Oil Flooded Air Compressors !

Typical Air End Failure

The Bearings that hold the Twin Rotors in position; need to replace regularly, 

Otherwise !!!!!

The Twin Rotors :

The Male - usually the drive,

The Female - usually follow

Air End Bearings: 

Type and sizes of bearing for this air end are:

HM 911210 = 4 pcs HM 911244 = 4 pcs 

NU 211 ECM/C3 = 1 set 

NU 311 ECM/C3 = 1 set 

 Note:= 

There are three types of bearing cage to choose from, there are NU 311 ECJ = Steel cage 

NU 311 ECP = Polymide cage [ a type of plastic material ] 

NU 311 ECM = Brass cage
