Special Versions of Locknuts

In addition to the well-known advantage of the Spieth locknut design (high locking effect, easy to install / good serviceability), the customized design also reduces the number of components of the spindle, which in the end leads to less tolerances and as a consequence a higher precision of the spindle system.

Spieth locking systems allows reliable securing of bearings even at high rotational speed. As the elastic membrane system assures fast and easy assembly, disassembly and re-usability of the locknut, overhaul times for the tools could be reduced to a minimum.

Spieth locking principle of the locknut with an elastic membrane system allows precise setting of pretensioning forces. 360° locking at the shaft assures that forces will be kept during operation of the rotary table.

Spieth locking principle of the locknut with an elastic membrane system allows precise setting of pretensioning forces. 360° locking at the shaft assures that forces will be kept during operation of the ballscrew. The 8µm runout accuracy of the clamping set assures minimized vibrations of the system which will result in a precise positioning of the ballscrew and a long lifetime of the connecting components.
