Quality bearing paper
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 paper roller bearing

In the past 3 years, ZWA is dedicated to the R&D of bearings for paper mills. ZWA paper bearing applied in paper mills can adapt to the misalignment and length change of the rolls. With the bearings of ZWA, a local China bearing factory, 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, the spherical roller bearings with precision 5 from ZWA, who is known as the China Spherical roller bearing supplier, 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.
