💡 Why does a treadmill belt slip during heavy runs?
A faulty deck tension axle lets the running surface drift right out of center. Installing this handy rear idler assembly brings everything back into proper alignment.
- Axle preload torque locks the roller housing against deck shift
- Increased track friction kills belt slap and reduces motor strain
- High tensile steel core takes constant cardio mileage without bending
