Treadmill Overview
What Is Treadmill?
Nowadays, a treadmill or treadwheel is used to practice walking, climbing, or running purposes. However, the origin of treadmills dates back to 4000 years ago, meant for grinding grain by human or livestock' power. Later in the 1800s, it was a tool for torturing inmates.
In the modern-day, treadmills or treadwheels are not responsible for punishing or grinding; instead, it is a right-hand man that helps people get in shape, lose weight, and release stress.
The components of the modern treadwheel are conveyor belts and flywheel or electric motor. Users will run on the surface of the conveyor belt, which moves by the power generated from the flywheel.

Health Benefits Of Using Treadmill
- Running on a treadwheel mitigates the impact of exercising on the knee and foot compared with running or jogging outdoors. Outdoor terrain is rough, and you might end up injuring yourself when misstepping on a rock or a hole on your running track.
- A workout on a treadmill instead of jogging outside will save you from exposing yourself to hazardous substances and pollutants in the air.
- Many unexpected incidents might happen to you that you can not control. Still, treadmill exercising allows you to control everything from the speed distance to the terrain's inclination.
- Walking or jogging on a treadwheel improves your mental and physical health. It helps relieve stress, enhance your immune system, and make you happier. Those who want to lose weight, lose fat, and build muscle also benefit from this practice.

What Cause Treadmill Loud When Running And How To Fix It
Treadmill Belt
The most common culprit of your treadmill loud when running is the belt. It sounds like a whirring, buzzing sound. Aside from dust and oil, cleaning beneath your belt may be able to aid as well.
Oiling the belt every month will help it work properly without noise. To achieve the best result, you should use lubricants which have the main ingredient is silicone.
After lubricating and cleaning, pay attention to the tension of the belt. Fasten it if it loose by tinkering with the bolts closed to the roller.
Motor
It's quite an unusual case. The engine, powered by a motor, seldom makes disturbing noises as it usually goes through several quality tests. However, when moisture or water gets into motor or fan bearings, they may damage and generate sounds.
When you're in this circumstance, you shouldn't try to fix it yourself as you might end up damaging the whole machine. Instead, contacting the experts is a better idea.
Roller
Rollers can make your treadmill loud when running from time to time. The good news is that you can fix it on your own easily and quickly without consulting professionals.
To begin, separate the covers and inspect the neighboring screws for looseness. Use a screwdriver to tighten the screws if necessary. Also, make sure to inspect the roller attached to the belts and lubricate them as necessary.
Treadmills that cost more are usually quieter than low-price models. If the noise from your treadwheel is torturing you, you may want to consider upgrading to a higher-quality one.
Uneven Placement
The machine's vibration or noise may result from an uneven or misplaced surface. Exercising on a treadwheel that isn't perfectly adjusted could be a little dangerous, as well. Your floor may potentially be damaged or scratched by using these fitness devices.
Putting the machine to a flat, clean surface is one of the best options. However, replacing your running belt or roller could be necessary if this issue continues.
Belt tension might be lost as a result of repeated usage. Then, you'll need to purchase a new one and change it. To replace the running or roller belt, read the handbook carefully and follow its steps.

Misaligned Parts
The loose and misaligned bolts and nuts also cause the treadmill loud when running. When a bolt comes free, it might generate noises that imply something is damaged within the bolt head. To fix it, gently open the machine and tighten the bolts.
If the worst happens, a damaged or malfunctioning internal element will need a new one. It's advisable to consult the manufacturer and see whether they can help you get your warranty back.
But once it becomes too much of a headache and no longer worthwhile, you may want to look into purchasing a new treadwheel.
Bearings
Broken bearings are also the most common source of your treadmill loud when running. To inspect the condition of bearings, you can find them in the front of the machine, then add some oil to lubricate them. If the noise doesn't disappear, you might need to replace it.
Others
Sometimes the treadmill loud when running does not come from the broken or misaligned internal parts. It is due to the owner's wrong usage. When you are running too hard on the belt, it also creates deafening noise.
Therefore, slowing down the speed or declining the vertical oscillation would be of great help.
Maintenance To Prevent Treadmill Loud
Lubricate
To avoid the treadmill loud when running, lubricating it periodically is necessary. We highly recommend you oil the running machine annually if you don't use it usually. Otherwise, a quarterly lubrication should do the trick, given that you exercise on the treadwheel daily.
A reminder is not to abuse lubricant, especially WD-40, as it might impair your belt.
Cleanse
After each usage, be sure to clean off your treadwheel. Doing it is significantly more critical for those who regularly work out.
When water or moisture leaks into the machine, it can lead to metal corrosion, making the machine noisy when operating and the development of germs and fungi.
Using a cleaning kit for the treadwheel may be more convenient than using a moist towel.
Besides, this task prevents any dust from getting inside the parts of the machine and causing any damage. Vacuum the surrounding area where you place the machine every week.
Check For Worn Parts
Any rusted or worn parts also cause the treadmill loud when running. As such, you should examine the deck and belt weekly for any signs of wear and tear.
In terms of nuts and bolts, check them monthly to replace the corroded bolts and tighten the loosened nuts.
Place A Mat
The purpose of a mat beneath a running machine is to preserve the ground rather than the machine itself. An anti-scratch mat can protect the floor and reduce noise it might cause if the treadwheel is installed in an upper-story room.
Conclusion
That's all the causes and solutions for the treadmill loud when running. You can handle these issues by yourself without further assistance from the experts. However, when the problems are out of control, asking for help is a better option.
To keep yourself from these unnecessary hassles, you should spend a few minutes periodically examining your running machine to make sure that it is in optimal condition.
