Innovative spreader roll technology from Voith

Healing powers

Steel Ball
Ceramic Ball

Steel ball bearings are essential components in spreader rolls, but over time they become damaged and also cause considerable damage to the raceways. Unlike ceramic balls.

As ceramic is harder than steel, the material can withstand the millions of rolling movements during production far better. What’s more, ceramic balls have the capacity to polish, smooth and “heal” any imperfections on the raceway surfaces caused by the tiny particles that often break off during operational life. “Combined with a very special design for spreader roll bearings, it takes just one ceramic ball to provide self-healing power for a longer life,” highlights Thomas Weisshappl, Director Spreader Roll Global, Voith Paper.
