In electric motors, two types of shaft supports are used: rolling and sliding bearings. The choice depends on power, speed and operating conditions. Let's look at the differences.
Rolling bearings
The most common type is ball and roller bearings. Installed on most engines of low and medium power.
- Pros: low friction, easy replacement, accessibility, do not require a complex lubrication system.
- Cons: noisier, limited to the maximum speed of large machines.
Sliding bearings
The shaft rotates in a sleeve with an oil film. They are used in powerful, high-speed and low-speed heavy machines.
- Pros: quiet operation, huge resource, withstand heavy loads.
- Cons: require a lubrication system, more difficult to maintain and repair.
Comparison
| Parameter | Rolling | Sliding |
|---|---|---|
| Application | Low/medium power | Large machines |
| Noise | Higher | Lower |
| Maintenance | Simple | Complicated |
| Replacement | Fast | Requires qualifications |
What is important for operation
Most industrial engines in Tashkent use rolling bearings - their replacement is simple and inexpensive. Powerful machines with plain bearings require lubrication control and professional maintenance. In any case, timely diagnosis of bearings prolongs the life of the engine.
