A treadmill is the most common fitness instrument that can be found in almost every gym, or in a house of health-conscious people. Although its primary function is to help a person in walking, jogging, or running within a closed area, tens of features have been added to it over the years to make it user-friendly equipment. However, like all the other mechanical instruments, a treadmill does have finite longevity. Depending on the brands, specifications, and parts quality, this machine can last as long as 10 years. Here, the highlights of this article will be parts replacement options for a treadmill.


Common parts that need replacement

For a treadmill, there are four parts that are needed to be replaced more often if not used properly. Those parts are-

1. Walking belt: A belt needs to be replaced if the runner finds problems like improper belt tension, loss of smoothness, and a worn-out look.

2. Motors and controller: Sometimes when the belt tension and speed don’t seem to be accurate, the problem might lie with the motor instead of the walking belt.

3. Rollers: Sometimes the runners hear grinding noise while using the treadmill. And this sound might signal the problems in the roller.

4. Drive belt: A user will experience braking issues when this part isn’t working properly.
