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. 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 alarms; 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."

SPM^®HD

SPM^®HD is a development of the well known and reliable True SPM^® method, commonly recognized as the best method for measuring bearing condition on rotating machinery.

Highly advanced digital technique and RPM-based sampling frequency makes it particularly well suited for condition monitoring on low speed applications. Extraordinary signal quality and 24 bit A/D conversion provides razor-sharp resolution and exceptional detail in spectrums and time signals. Time signals are very easily interpreted; the type and extent of the damage is therefore simple to determine. Occasional measurements will provide a reliable diagnosis. Up to six months forewarning gives ample time to plan maintenance and repairs.
