Replacing bearings is one of the most frequent and inexpensive operations when repairing an electric motor. But the price can vary significantly depending on the type of machine and bearings. Let's look at what the cost is made up of and why it is dangerous to delay this work.
What makes up the price
- The cost of the bearings themselves.Depends on the size and manufacturer. Imported bearings (SKF, FAG) are more expensive, but last longer.
- Dismantling is labor-intensive. On stuck bearings, removal takes longer, sometimes a puller or heating is required.
- Condition of the seats. If the fit on the shaft or shield is broken, restoring the seat is a separate job.
Signs that it’s time to change the bearings
Do not allow it to jam - this can cause damage to the shaft and winding. Replacement is needed if:
- A hum or howl that increases with speed.
- Increased engine vibration.
- Heating of the bearing shields.
- Shaft play when rocking.
Why you can’t pull
A worn bearing is a chain reaction. The rotor begins to touch the stator, the iron is destroyed, the winding overheats and fails. As a result, instead of inexpensive replacement of bearings, you get a complete rewinding of the winding - and this is ten times more expensive. Timely diagnosis in Tashkent pays off many times over.
What is included in the work
High-quality replacement of bearings includes: disassembling the engine, removing old bearings, checking the seats, installing new bearings with proper heating/pressing, adding lubricant, assembling and checking the stroke. After assembly, the engine must be checked for runout and heating.
