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 Arrangements in Paper Machines 

The typical requirements are as follows - 

  • Utmost operational reliability 
  • Easy mounting 
  • Compensation for misalignment 
  • Avoidance of corrosion in wet sections 
  • High-speed capabilities 
  • High bearing quality and precision 

 A paper machine is expected to operate without any interruption and should only shut down for maintenance work. Therefore, demand for bearings with utmost reliability and operational safety are given the topmost priority while selecting bearings. The bearings must be able to withstand misalignment and length variations. Properly sealed bearings are chosen to avoid penetration of water and corrosion. 

Spherical Roller Bearings 

According to the present scenario, the papermaking industry shows a continuing increase in output which raises a need for larger machines that can work at higher speeds. Therefore, the bearings must meet the increasing needs of heavy loads and speeds. i.e have a longer service life with reduced maintenance, cost and charges. 

Mostly spherical roller bearings are used in papermaking machines because of their capacity to accommodate radial and axial loads. Spherical Roller bearing permits misalignment between shaft and housing which is important for paper machines. INA and FAG rolling bearings for paper machines deliver excellent design, durability and top quality. 

Services for Rolling Bearing products and applications 

Paper lines have to operate continuously without failures and problems round the clock for 365 days a year. Capital-Intensive paper lines require permanent availability, which is provided by top-quality equipment and an intelligent lifecycle service. Therefore, it is important to use reliable products & services for mounting and maintaining the rolling bearings used in the bearings industry. We at Premier Bearings accept these challenges and try to offer a wide range of services to provide complete bearing solutions for all stages of papermaking.

Schaeffler’s Arcanol: Elevating Bearing Performance with Advanced Lubrication

Image
  Choosing the correct lubricant is essential in ensuring that rolling bearings and linear units can achieve the desired performance and service life. Schaeffler's Arcanol lubricating greases undergo rigorous quality tests before supply. The quality of each batch is thoroughly tested and accounted for. In Schaeffler’s own analytical laboratory, the Arcanol lubricating greases are checked for their chemical and physical properties following strict guidelines to ensure high product quality. Lubricants Schaeffler’s lubricants offer significant benefits, enhancing the running behaviour of bearings and extending the life and operational reliability of the bearing arrangement. The lubricant range is graduated in such a way that it can be used in almost all areas of applications. This is evident as they can withstand various operating conditions and are suitable for all rolling bearings due to their completion of different testing procedures. In 2015, Schaeffler conducted over 50,000 hou...

The Role of Bearings in the Aviation Industry

Image
  Though small in size, bearings are the backbone of many industries that involve rotary machines and equipment. The aviation industry is no exception. However, this industry demands bearings that can handle extreme heat and immense pressures. They should be able to operate efficiently in corrosive environments. In this blog, we look at a few important applications of bearings in this aviation industry. Key Applications of Bearings in Aviation Bearings offer frictionless, smooth rotational, and linear motion between moving parts in the aviation sector. Commonly, in aircraft components, they are used in engines, flight control systems, and auxiliary power units. Flight Control Bearings Control bearings are specially designed to ensure smooth and responsive aircraft maneuvering. But how do these bearings help? Basically, they minimize friction and enable precise movement of control surfaces like ailerons, elevators, and rudders. For example, flight control linkages rely on spherical ...

Types of Main Bearings Used in Marine Industry

Image
  Lead Bronze, Bi-Metal, and Tri-Metal bearings: These three types of bearings play a huge role in the marine industry. They are utilised to support rotating shafts and reduce friction to ensure smooth rotations. These bearings come with distinct benefits such as high load-bearing capacity, wear and corrosion resistance. Let us explore what these three bearings are made of, how many layers they have, and what they are used for. Lead Bronze Bearing Flash layer: This topmost layer is composed of tin and lead. It is 0.035mm thick. This layer’s job is to protect the bearing from getting corroded and dust when not being used. It flashes off when a bearing is running. Nickle Barrier: This 0.02mm thick layer - made of nickel - helps prevent corrosion and avoid diffusion of tin into bearing metal. Lead Bronze: The third layer comes with an anti-seizing property. It is made of lead bronze. This layer is great at preventing parts from sticking together. In the setup, it is the main part th...
