Hallsta Paper Mill measures bearing condition with SPM HD
"Since April 2009, we have been engaged in a project together with SPM, where we have measured bearing condition on four of our twin wire presses with SPM HD® measuring technique. To maintain pulp quality, it is essential that these presses work properly. Any breakdowns also lead to major costs for damaged rolls."
"Over the years, we have tried a number of different measuring techniques on these presses, but SPM HD is the first one to detect developing bearing damages. The measuring technique is very reliable and has not generated any false alerts; every time the system has indicated damage, it has proven correct when we dismounted the bearing. The forewarning time has been as long as up to six months. The technique is easy to use and the measuring results are easily understood. Thanks to SPM HD, we have found six damaged bearings, which we have been able to attend to through planned replacements." Per Ljungström, Preventive Maintenance Engineer, Hallsta Paper Mill
