Production

Products

(Tandem thrust Roller bearings)

IDC Tandem Thrust Roller Bearings = Multi-stage axial roller bearings designed to handle extremely high axial loads in limited space, with precise alignment, low friction, and long service life.

 
They are used in heavy industrial machinery and extruder gearboxes where axial forces are intense. 

    • Extruder gearboxes for injection molding and profile extrusion applications in the plastics industry

    • Pelletizing systems used in the feed and food industries

    • Plastic granulate production in the petrochemical sector

    • Drilling equipment for industrial applications

    • absorbtion of high thrust loads, generated by back pressures from extruder screw

    • small radial space consumption

    • small distance of shafts in twin screw extruders realizable

    • high lifetime

    • low friction torque

    • even load distribution

    1. Gearboxes for single & twin‑screw extruders (plastic & rubber industry) 

    2. Heavy-duty gear reducers 

    3. Printing machinery 

    4. Construction machinery 

    5. Metallurgy equipment 

    6. Deep-hole drilling machines 

    7. Friction welding machines
