💡 How does correct belt tension and tracking setup affect the lifespan of a bench sander motor?

Solid maintenance habits stop premature failure so you avoid costly replacements down the road. Here is how it breaks down
- Proper tension keeps the belt centered which reduces strain on the three-bearings and extends the motor life considerably
- A handy habit includes verifying the belt angle lock daily since loose setups vibrate the frame and loosen internal parts
- Monitoring load prevents overheating because forcing the grind stresses the windings so let the belt do the work naturally
