Germany · Precision machine elements — locknuts, clamping sets, guide bushings and plain bearings
Spieth-Maschinenelemente GmbH & Co. KG was founded in 1953 in Esslingen, Baden-Württemberg, Germany. It specialises in precision connection technology built on the "Spieth principle" — axial clamping force is converted into a uniform, all-round radial clamping force, giving a highly accurate, friction-locked shaft-hub connection. Products are machined to tolerances in the thousandth-of-a-millimetre range and serve machine tools, automation and test equipment.
We carry the Spieth range of precision locknuts, clamping sets, guide bushings, guide gibs and radial plain bearings, matched to shaft/bore diameter, clamping force and installation space. Common MSR/MSA locknuts and FSK guide bushings are stocked; less frequent sizes are sourced through the manufacturer and established distribution channels with documentation. All units are original and new.
Below are commonly requested parts. Unlisted numbers can also be quoted — just ask.
Spieth uses the friction-locked principle: axial clamping force creates a uniform, all-round radial grip, giving high concentricity and locking accuracy that survives repeated assembly — ideal for precision spindles and drivetrains.
Give us the shaft diameter, hub bore, transmitted torque/axial force and the space available; we check the DSK/DSL, DSM, AK/IK and AL/IL series and propose the right size.
Yes. FDK/FDL, FSK/FSL and FAK/FAL guide bushings and the FLW guide gib are ordered by article number, with clearance set as needed.
Common MSR/MSA locknuts and FSK guide bushings are stocked for fast shipping; special sizes are sourced through the manufacturer and established channels, confirmed in the quote.
Yes. We buy through the manufacturer and established distribution channels and can supply the matching paperwork; units are original and new.
