High performance bullnose live centres

ZA Series – robust – precise

Our bullnose live centres have sturdy roller bearings where the loads are heaviest. Combined with large axial and radial deep section ball bearings this design allows high loads with high concentricity and long life. BRUCKNER bullnose live centres sustain their reliability even when conditions are tough. For cylindrical grinding operations BRUCKNER bullnose live centres are market leaders.
