Issue:
How many bearings are used on the screw compressors?
Resolution:
Number of Bearing used in Pueblo-built screw compressors:
- RTHA and RTHB All had 9 bearings which included a reverse thrust bearing on the male and female rotors.
- RTHC and RTHD All have 7 bearings The reverse thrust bearings from the RTHA/B design were removed.
- Intermediate and GP (RTAA, RTWA, RTUA) Original design had 9 bearings which included the reverse thrust bearings. They were later deleted and now have 7 bearings total.
- GP2 (RTAC) All have 7 bearings. The design did not include the reverse thrust bearings.
The breakdown is as follows:
Male -
- Suction 1 bearing
- Discharge 3 bearings
Female
- Suction 1 bearing
- Discharge 2 bearings
Four of the bearings are classified as Cylindrical or "Roller" type while the other three are Angular Contact or "Thrust" type.
- GP4 (RTAE) - All have 8 bearings. The design did not include the reverse thrust bearings.
The breakdown is as follows:
Male:
Suction - 1 bearing
Discharge - 3 bearings
Female:
Suction - 1 bearing
Discharge - 3 bearings
Four of the bearings are classified as Cylindrical or "Roller" type while the other three are Angular Contact or "Thrust" type.
