If you notice that the air in your home isn't blowing as well as it used to, you should consider troubleshooting your blower bearings
. This problem can be caused by a variety of factors. One of the most obvious is that the motor is not turning smoothly or is overheating. This can be caused by the motor's bearings failing, or rust formation in the inside of the motor.
Blower bearings often have double-row ball bearings. These are more susceptible to failures than other styles. You can determine the bearing's condition by monitoring its temperature.
Problems with blower bearings can occur in a number of ways. These issues can lead to unusual noises and elevated temperatures. Ideally, bearing temperatures should be below 100 degrees Celsius. However, this temperature may rise as the blower starts up. Generally, the bearings will reach a temperature of 10 to 40 degrees Celsius above room temperature. One solution to bearing issues is to replace the entire motor. However, this may not resolve the problem in the long run. To avoid these problems, it's important to use vibration isolation. Using this method can prevent noises and uneven running.
Premature bearing failure can cause considerable downtime and lost productivity. The best way to avoid bearing failure is to prevent it from happening in the first place. Premature failure can be caused by many factors, but fortunately, most are preventable. Some of these factors include improper mounting and alignment, improper lubrication, and operational stress. Improper storage is another common cause.
