BALL BEARING con cuscinetti a sfera

The Ball Bearing System – spring tension with ball bearing: it is always a system with a directly adjustable knob, but it is considered among the most sophisticated and among the best tensioning systems. In addition to the classic knob, it has a circular structure with a stabilized ball collection ring in its interior; ball bearings further stabilize the blades, spreading tension. Its stability makes cutting comfortable, effortless. The Ball Bearing screw does not come loose easily, in fact, it holds the set adjustment for a long time All these features make the Ball Bearing system especially efficient in daily professional use. In case one of these pieces is lost, an experienced grinder will quickly replace it.
