Fitting Sleeve Bearings

  • August 2020

Article

When sleeve bearings are rebabbitted or replaced, an important step during assembly is to check the contact between the sleeve bearing and the journal which rides in it. The use of self-aligning sleeve bearings (also called spherical or ball fit) renders this step almost unnecessary. Still, cylindrical sleeve bearings should be inspected to make sure the contact area is sufficient. This article is specific to checking and correcting the wear pattern when installing a new sleeve bearing in an electric motor.

Cuando se rebabitan o se reemplazan cojinetes de deslizamiento, un paso importante durante el montaje consiste en verificar el contacto entre el cojinete y el muñón del eje que monta sobre el. El uso de cojinetes de deslizamiento auto alineables (también denominados esféricos o de ajuste esférico) hace que este paso sea casi innecesario. Aun así, los cojinetes de deslizamiento cilíndricos se deben inspeccionar para verificar que haya suficiente área de contacto. Este es un artículo específico para verificar y corregir el patrón de desgaste al momento de instalar cojinetes nuevos en un motor eléctrico.

It happens to just about every EASA service center. A machine shows up for repair; it has leads, and there’s a motor, but the machine is a pump. Most often, it’s a close-coupled pump or a submersible pump. If your response is, “We don’t work on those here,” because you’re thinking, “We don’t know anything about repairing pumps,” you may be turning your back on some very profitable work.
