Our design team applies modern CAD software to create 3D models of the bearing complete with the chock and roll neck. Just as crucial is detailed FEM analysis for optimal bearing components and backup roll necks. To validate and update our bearing dimensioning software, we regularly record bearing data under true load conditions in mill stands. Using model techniques, we simulate the fluid flow and physical properties and analyse the elasto-hydrodynamic behavior of the bearing.
It makes sense to revamp and extend older mills so they can handle today’s challenging products. That ensures your long-term competitiveness.
Included in the critical components are the backup roll and bearing unit. To start with, we team up with you to determine the current status of your bearing system. Then we perform a thorough analysis. This is how we identify what optimizations will get the best out of your system.
There is plenty of scope for practical improvements in areas such as safe handling of the bearings or better sealing systems. These can make all the difference.
