Locknuts from SKF
SKF have introduced their new HMS locknuts that are designed to improve the process of locking, mounting and demounting large components.
HMS locknuts consist of a slotted ring body fitted with a clamping bolt that provides more effective locking and mounting than traditional models. By tightening the bolt the nut is located without clearance around the whole circumference of the shaft. Traditional locknuts have between four and eight slots machined into the shaft, which necessitates a corresponding number of collars and bolts. However, with no axial slots needed for fitting the locking devices, HMS locknuts provide substantial component savings. The lack of axial slots and locking nuts also speeds up the placing of the nut and gives secure fastening all around the shaft.
HMS locknuts are suitable for fast and exact axial location of large components such as gearwheels, flywheels and large-size bearings.
