rolă încrucișată

Inelul de rotire cu rolă încrucișată este compus din două virole, cu structură compactă, greutate redusă, precizie ridicată și spațiu de asamblare mic. Rolele se intersectează una câte una, astfel încât inelul de rotire să poată suporta sarcini mari axiale, radiale și momente de răsturnare. Rulmenții cu role încrucișate cu un singur rând sunt potriviți pentru echipamente de ridicat și alte mașini de construcții.

  • Diametru exterior: 602mm~4726mm
  • Ball Diameter: 25mm~50mm
  • Sarcina nominală: 104kN~1980kN

Crossed roller slewing rings consist of square raceways and cylindrical rollers instead of balls. The complete contact of the rollers (compared to only 4 ball points) increases the load capacity of this type of bearing, especially for radial loads. This type of bearing also has less internal clearance than ball bearings, typically 0.0-0.03mm (preloaded) axial and radial. While this increases the starting torque, it also increases the precision and stiffness of the bearing, making it especially useful in precision applications.

  • Suitable for medium to heavy duty applications
  • Precizie și precizie ridicate
  • High Rigidity and Rigidity
  • constant rotational resistance
  • higher rotational torque
  • Accepts all combinations of axial, radial and tilting moment loads
  • Available in gearless, internal and external gear versions
  • Can be used for induction hardened gears
  • Typical sizes range from 300mm-2000mm, other sizes are available upon request.
  • Different anti-corrosion coatings available
  • Pinionii potriviți sunt disponibile pentru toți rulmenții de rotire.
