Applications

  • Activation of transporting rollers on hot-rolled lines at iron & steel plants
Obeki Rollers

Characteristics

  • OBEKI Roller Table-type motor torque for roller track
  • Applications with high temperatures and atmospheric humidity
  • Mechanically resistant to highly variable mechanical loads
  • Study of the work cycle in new projects to correctly size the motors (analysis of resistance torque, accelerator torque, momentum, etc…)
  • Radial fin framework improves surface cooling and condensation evacuation
  • Assembly of B3 legs or B5 flange. Others on request
  • Circular, square or rectangular flanges. Made to measure for simple assembly in existing installations
  • Cast iron, ductile iron and machine-welded steel frames
  • Protection level up to IP66 in motor and terminal box
  • Designed for any type of service (S1, S2-30', S3…)
  • Insulation class H
  • Terminal box available in back, top or side position, depending on the physical requirements of the assembly
  • Possibility of a stator sealed in resin to protect against condensation
  • Stainless steel screws
  • NU-type front roller bearing
