Total Indicated Runout - Why is it important while selecting your polyurethane rollers?

07/15/2025

How important is total indicated runout (TIR) when selecting a polyurethane drive roller? TIR measures how concentric a rotating part is. In this video, we compare an off-the-shelf competitor roller (0.008” TIR) to Meridian Laboratory’s ML6 roller (0.0005” TIR), 16 times more precise. Excessive TIR causes bounce, vibration, misalignment, or jams. ML6 rollers consistently achieve <0.001” TIR, ensuring smooth performance in precision applications. Watch to see the difference.
