SPIETH

Spieth is a technological leader and provider of mechanical connecting, bearing and locking solutions for drive and guide components.

Spieth connecting components are one-piece, rotationally symmetrical elements that fulfill their clamping, gripping, locking and guiding functions thanks to their elastic deformation. Axial force is applied to them to activate the function. As a result of the elements’ geometry, all elastic movements are made with maximum symmetry and take advantage of the high production quality of the Spieth components to align the connection.

• Precision Locknuts

Precision nuts with a high-quality locking system (premium thread-locking). Spieth locknuts with the unique Spieth principle can be set exactly to the demanding tasks in mechanical engineering with extreme precision and even clamping forces on the thread flanks.

• MSR - Standard Locknuts

Can be freely, infinitely and exactly positioned. Reliable locking without additional grooves or locking plates. Quick and precise assembly and disassembly.

• MSR (Inch) – Standard Locknuts

Imperial locknuts designed with a thread range of 17mm x 32 threads/in to 200mm x 8 threads/in or 5/8” x 18 to 3” x 12.

• MSA - Reduced Face Contact Locknuts

MSA series locknuts with a reduced contact surface and some of which have smaller external diameters than the MSR series are particularly suitable for the assembly of angular ball bearings and cylindrical roller bearings (ISO diameter series 9).

• MSF - Low Profile Locknuts

For applications with limited installation space.

• MSW - Heavy Duty Locknuts

Can be freely, infinitely and exactly positioned. Reliable locking without additional grooves or locking plates. Quick and precise assembly and disassembly.

Keyless Clamping Sleeves

Friction-locked shaft-hub connections providing all-round pressure. They are more accurate, precise, efficient, and easier to assembly and more service-friendly thanks to the Spieth principle.

• DSK/DSL - Integrated Clamp Screws

Ready-to-use friction-locked shaft-hub connection for quick and easy assembly. For shafts with an h-tolerance zone.

• DSM - Integrated Clamp Screws

Ready-to-use friction-locked shaft-hub connection. For motor shafts in accordance with DIN 748 with a k/6/m6 tolerance zone.

• AK/IK – External Clamp Force Initiation

Friction-locked shaft-hub connection that can be automated. For shafts with h tolerance zone. Clamping force initiation can be freely configured. Series IK for clamping force initiation from the shaft.

• AL/IL – External Clamp Force Initiation

Friction-locked shaft-hub connection for shafts with an h-tolerance zone. Clamping force initiation can be freely configured. Series AL for clamping force initiation from the borehole.

• Guide Bushings

Spieth guide bushings – round guidance and clamping with adjustable play – open up new dimensions for modern, efficient and economical machine designs with high power densities and high levels of dynamic stress thanks to the Spieth principle.

• FDK/FDL – Guide Bushings (External Play Adjustment)

Precise round guidance with adjustable play. Good value for money and ready-to-use. Sliding friction in combination with a minimal guiding tolerance is possible. Adjustable during assembly. Connecting parts are easy to produce. High attenuation. Simple and easy assembly and disassembly.

• FSK/FSL – Guide Bushings (Internal Play Adjustment from Clamp Screws)

Precise round guidance with adjustable play. Good value for money and ready-to-use. Sliding friction in combination with a minimal guiding tolerance is possible. Adjustable during assembly. Connecting parts are easy to produce. High attenuation. Simple and easy assembly and disassembly.

• FAK/FAL – Guide Bushings with Clamping (External Force Initiation)

Precise round guidance and clamping with adjustable play. Good value for money and ready-to-use. High degree of radial rigidity. High attenuation. Simple and easy assembly and disassembly, even with large dimensions.

• Hydraulic Sleeves

Spieth Hydraulic Guiding and Clamping Sleeves guide and automatically clamp machine components such as quills, guide bars, clamp and support posts on automatic mechanisms and machines.
