How to Reduce Operating Costs Through Bearing Remanufacturing?

  • In many industrial applications, bearing failure will seriously affect the operating cost. The bearing remanufacturing service can bring considerable benefits.How to Reduce Operating Costs Through Bearing Remanufacturing?
  • Combined with our bearing manufacturing standards, processes, equipment, quality, knowledge and expertise, SKF’s professional bearing remanufacturing services can bring many significant benefits to end users:How to Reduce Operating Costs Through Bearing Remanufacturing?

● prolong the service life of bearings

● reduce machine downtime

● reduce total life cycle costs

● reduce the impact on the environment

● improve spare bearing inventory

● improve overall asset reliability

How to Reduce Operating Costs Through Bearing Remanufacturing?

  • Only by understanding the specific application occasions of bearing manufacturing and use can the correct process be adopted, so as to ensure that the remanufacturing of bearing meets the requirements of application occasions.
  • The operation of bearings in continuous caster under extremely harsh and polluted working conditions is a typical application of bearing remanufacturing. 
  • In SKF’s bearing remanufacturing process, not only the bearing damage will be comprehensively analyzed, but also the cost will be carefully calculated. It usually includes:How to Reduce Operating Costs Through Bearing Remanufacturing?

● visual inspection to find out the type and depth of bearing damage

● measurement includes parameters such as clearance, Ovality and wall thickness difference of ferrule

● carry out additional non-destructive testing according to requirements or bearing specifications

  • The remanufacturing process also includes waste bearing cleaning and waste disposal, which contributes to the work of the enterprise in the field of sustainable development.
  • In this process, according to the needs of customer applications, SKF can also propose remanufacturing schemes to transform the bearing characteristics, change its specifications or upgrade to higher specifications, including:

● installation of sensors

● provide integrated lubrication

● provide sealing and coating solutions

Prevent damage

  • After remanufacturing, the use of SKF’s predictive maintenance expertise can avoid the recurrence of damage requiring remedial work:

● record all data of each remanufacturing case through the advanced management process, and specify the code for each bearing to track each bearing in the future life cycle

● SKF’s various monitoring services can provide information about the mechanical status of the plant

● provide failure root cause analysis, find out the causes and influencing factors of bearing damage, and formulate a comprehensive corrective plan

SKF has many remanufacturing service centers around the world.

  • In China,   SKF (Shanghai) Industrial Services Co., Ltd. (ISC Shanghai) is a joint venture established by SKF group in China to provide remanufacturing services for bearings and related products.How to Reduce Operating Costs Through Bearing Remanufacturing?
  • It is committed to providing remanufacturing services for large-size bearings, continuous casting bearings, backing bearings, slewing bearings and other related products to customers in China’s iron and steel industry and other industries. At the same time, it provides continuous casting roll system solutions for the iron and steel industry to ensure the normal operation of continuous caster and stable equipment operation.How to Reduce Operating Costs Through Bearing Remanufacturing?

  • In either case, the game will be reduced. Therefore, if the bearing before installation does not have a certain clearance, negative clearance will be generated after installation. 
  • The rolling body (ball or roller) inside the bearing will bear additional load, increase friction torque and temperature rise, and make the bearing bite or damage prematurely. Moreover, when the bearing rotates, the rolling temperature is higher than that of other parts, and its thermal expansion will also reduce the clearance. Therefore, the bearing is also required to have a certain clearance.
  • But it doesn’t mean that the larger the clearance, the better. If the clearance is too large, vibration and noise will be generated when the bearing rotates, and the load distribution inside the bearing will deteriorate, resulting in early damage. Therefore, the clearance must be appropriate and appropriate.
  • When the bearing has internal clearance, if the inner ring is fixed, the outer ring will be in a multi degree of freedom movable state. 
  • According to its movement direction, the clearance can be mainly divided into radial clearance, axial clearance and angular clearance. The geometric relationship of these three clearances is determined by the internal size of the bearing. In addition, the clearance also determines the contact angle of the steel ball in the bearing.
  • Mechanical knowledge is complex and diverse. A small part will have great functions and many classifications. Such as bearings. As long as the rotating equipment is inseparable from the bearing, it is known as “industrial grain”.
  • For people who are often in contact with machinery, we all know that the role of bearings can not be underestimated. The relevant knowledge and functions of bearings are inevitable in our work and life. Here is a brief introduction to the basic knowledge of bearings.
