Bearing selection
Thread Content
During the training, I encountered a problem: there is a hot oil cantilever pump (with balance ribs and an impeller diameter of 500 mm), and its bearings have burned out; it’s not possible to determine the bearing codes. The diameter of the shaft journals is 70 mm each. How should I choose the bearings? I thought it over and chose bearings from the NU series and the 6 series. I would like to ask fellow sailors which model of bearings you would choose?
One set of NU314EM, two sets of 7314AC2 installed back to back! First, check the bearing dimensions to see if it can fit in the bearing housing!
One end is fixed (mounted back-to-back with 7314), while the other end moves freely – NU314
Install 7314+NU314 back to back, or double-row angular contact ball bearings 3314+NU314
