Self-locking threaded fasteners assessed by institutions
According to tests undertaken by institutions such as MIT, the Goddard Space Flight Center and others, Spiralock's thread locking form outperforms standard fasteners in terms of resistance to vibration, axial-torsional loading, joint fatigue, and thermal extremes.
Benefits of split roller bearings in papermaking machinery
The continuous nature of papermaking, the huge production capacity and the substantial capital investment means that unplanned downtime in paper plants is extremely expensive. And planned maintenance windows are becoming shorter and less frequent. Yet the opportunity for slashing downtime by using split roller bearings instead of solid bearings is often ignored.
