Paper Making

Quality Bearings for Paper Making

Nowadays, the paper and paperboard are extremely huge and their length can reach 200 meters. The paper web pass many rolls and the rolls are all supported by bearings. In general, paper mills contain the wet part and drying part. The configuration of paper mills differs according to the products they produce. But no mater the paper mills are fast or slow, wide or narrow, they must all be configured to the maximum efficiency and profit. Paper mills work continuously without stop until planned maintenance is carried out. The priority requirement for the bearings is the safe operation and reliability. Meanwhile, the lubrication and maintenance are also important.


The Function of ZWA Bearings in Paper Making 


In the past 3 years, ZWA is dedicated to the R&D of bearings for paper mills. ZWA bearings applied in paper mills can adapt to the misalignment and length change of the rolls. With ZWA bearings, the customer can realize the following goals:

  • Reduce the operating cost 

  • Reduce the maintenance cost

  • Increase the productivity 

  • Optimize the operation of mills 

  • Easy for mounting and dismounting 

  • Prolong the working hours 


ZWA' s Different Bearings In Paper Making 


ZWA’ bearings for paper mills cover from wet part to drying part, from drive rolls, plan press rolls, drying cylinders to vacuum rolls etc.


For drive rolls, ZWA’s exploiter series spherical roller bearings and circular ring roller bearings with good lubrication help to reduce the misalignment and water present. The spherical roller bearings can bear more misalignment of the roll and circular ring roller bearings can eliminate the residual load and prolong the service life. 


For plain press roll, ZWA’s spherical roller bearings with precision 5 are capable of reaching high running accuracy at high speeds. Those bearings are with even more strict tolerance and higher precision which reduce the friction and increase the reliability. 


For drying cylinders, ZWA spherical roller bearings can work well under high working temperature and higher stress.


For vacuum rolls, ZWA’s spherical roller bearings with P5 precision help to prolong the bearing service life and reducing the maintenance cost.

  • Spherical Roller Bearings

    Spherical Roller Bearings

    Spherical roller bearings are self-aligning and have 2-row rollers, a common spherical outer-ring raceway and 2 inner-ring raceways. The geometry of spherical roller accommodate the bearings to bear huge radial loads and resist the impact forces and dynamic loads. The bearings are active to misalignment of the shaft relative to the housing. Take it for example, the misalignment is caused by the deflection. The feature of spherical roller bearings is its special ability for bearing both radial and axial heavy loads. Spherical roller bearings usually undergoes more frictional losses and work at relative lower speeds.
  • Tapered Roller Bearings

    Tapered Roller Bearings

    Tapered roller bearings, also known as TRB bearing, are also a kind of bearing can be separated, a tapered raceway featured the inner and outer rings. In general, tapered roller bearings can bear both radial and axial loads. According to the different number of columns rollers, it can be divided into single row, double row and four row types. As a china tapered roller bearings manufacture, tapered roller bearings with the basic precision P5 provided by ZWA Bearings can accommodate to meet different requirements of the working condition, especially in those harsh working equipment like rolling mills. For those 4-row tapered roller bearings, ZWA usually adopt the same case hardened steel as TIMKEN to guarantee the best precision and performance of the bearings.
  • Cylindrical Roller Bearings

    Cylindrical Roller Bearings

    Cylindrical roller bearings mostly consist of the cage, the rollers and guided by two capped edges on a ring. It is a kind of bearing can be separated. Inner ring is independent and exchangeable. With this feature, it’s convenient to assemble or disassemble. In general, cylindrical roller bearings can bear high radial load and on the other hand, with the bearings structure, it can run well under high rotating speed.
