Roller bearings have a higher load carrying capacity than ball bearings. As a result, the radial forces are supported by roller bearings only, namely cylindrical roller bearings, tapered roller bearings or spherical roller bearings. The material used for the bearing rings and rolling elements is through hardening rolling bearing steel or, in ...

When a mill wants to increase paper machine speed, enhance roll reliability, extend maintenance intervals, improve paper quality, or eliminate maintenance problems, a roll modernization is the perfect solution. It can raise roll performance to a level higher than before. Modernizations are usually needed for: • higher machine speeds

• PROGRAM PROFILES: Represents the profile of the program being used (speed during speed based programs and incline during incline based programs). • FAN: Indicates fan setting (low, medium, high). • TRACK: Follows progress around a simulated track. Segments light up with every 12.5 meters completed. One lap around the track is 400 meters.
