Bearing Solutions for Pulp & Paper Manufacturing

Paper machines are among the longest industrial machines in the world, with thousands of bearings operating across conditions ranging from the wet and chemical-laden forming section to the high-speed, high-temperature dryer section.

Key Applications:

- Wet end (forming & press sections): Roll bearings use mounted Spherical Roller Bearings or cylindrical Roller Bearings with water and chemical resistance, often in stainless steel housings with specialized seals.

- Dryer section: Dryer cylinder journals use Spherical Roller Bearings or Cylindrical Roller Bearings operating at 100–150°C, requiring high-temperature grease or oil-air lubrication on high-speed machines.

- Calenders: Rolls use high-precision Cylindrical Roller Bearings to control roll deflection and ensure uniform line pressure.

- Winders & rewinders: Tapered Roller Bearings or cylindrical roller bearings handle significant radial and axial loads.

Selection Considerations: 

The wet end demands water and chemical corrosion resistance. The dryer section requires careful thermal expansion management and lubrication. As machine speeds exceed 2,000 m/min, bearing precision and dynamic performance become increasingly critical.
