Bearings for Papermaking Industry
Ever thought of how many bearings would a paper machine require? A modern paper machine can be more than 10 metres wide, 20 metres high and 200 metres long. These large machines incorporate as many as 15000 bearings! The operating conditions of these bearings depend on where they are placed. However, rolling bearings that are used here must withstand extreme heat, moisture, shaft deflections, high speeds and long lifetimes. A paper machine has a large number of rolls that consist of medium and large-sized rolling bearings & plain bearings. The spherical rolling bearings dominate the papermaking industry. Deep groove ball bearings, angular contact ball bearings and tapered roller bearings are used in accessory units of the papermaking industry. Spherical roller bearings, angular contact bearings and cylindrical roller bearings are used in the field of finishing and converting. Rolling Bearings & Plain Bearings Requirements of Bearing Arra...
