•  Four wheel groups “Bertoli ø 150 x 45”, twin installation, can be partitioned, two fixed and two pivoting, with threadguards.
  >    Our particular system of fork swivelling on vertical hub, allows to distribute the load on two ball bearings, and guarantees a great handling and long life. The rounded form of the rubber ring makes better all these characteristics.
  >    The rubber rings are belted with multiple layers of special rubberized canvas, to guarantee non-deformability and long life.
  >    Natural rubber ring studied and made to obtain more elasticity, long life, minimum traction effort.
  >    Imperforabile
  >    Acid, oil, solvent proof
  >    Trace proof
  >    Thermal resistance from + 180°C a – 45°C
•  Traction effort lower than 100 N/t: a top performance in its field
