Adjustable Round Guiding and Clamping Elements

Product catalog summary

Overview: The document details the specifications, applications, and assembly procedures for SPIETH Adjustable Guide Bushings, Series FAK and FAL. These components are designed for precise mechanical engineering applications, offering adjustable play and high damping performance for slideways.

Specifications: The guide bushings are made from spring-hardened steel with a plastic slide coating. They are configured to ISO tolerance levels, with the outside diameter at h5 and the borehole at G6. The maximum run-out is 0.01 mm. The plastic coating requires lubrication with petroleum-based lubricants as per DIN 51502 and 51517.

Functional Principle: The guide bushings allow for adjustable play between the housing, guide bushing, and sleeve. The play can be adjusted for a firm fit, ensuring freedom from play when clamped. The metallic support provides high radial rigidity.

Applications: These guide bushings are suitable for precise mechanical engineering fields where precise sleeve or column guidance is required. They are particularly useful in machine tools where absolute freedom from play is needed at standstill.

Benefits: The guide bushings allow for easy mounting with existing assembling play, even for large dimensions. They ensure maximum radial rigidity and can be adjusted for narrow guidance play during the mounting process.

Assembly Instructions: The document provides detailed steps for assembling the guide bushings, including inserting the guide bushing and ring piston, mounting the flange cover, and adjusting the shim ring. It emphasizes the importance of cleaning components and using low-viscosity machine oil before assembly.

Clamping and Transmittable Forces: The guide bushings are clamped hydraulically for complete freedom from play. The document provides formulas for calculating transmittable torque and axial force, considering the effects of lubrication and plastic coating on sliding properties.

Special Versions and Recommendations: Special versions of the guide bushings can be requested. The document also provides recommendations for minimum housing wall thickness and guidelines for adjusting guide play.

Figures and Diagrams: The document includes diagrams illustrating the execution of connecting components, sleeve guidance and clamping, and assembly examples. These diagrams help visualize the assembly process and the functional principle of the guide bushings.

Adjustable Round Guiding and Clamping Elements-3

Fields of application: > Series FAK-FAL guiding bushes areround linear guiding and clamping elements for all fields of precise mechanical engineering. The use of guiding bushes is called for wherever precise sleeve or column guidance is required and the sleeve/column has to be additionallyprecisely centrally clamped in anyoptional position. This is required,for example,for slee- ves on machine tools in which ab- solute freedom from play at standstill is called after positioning. The se- quence of clamping and release can be repeated as often as required. Benefits: > The simple to produce surrounding...

Adjustable Round Guiding and Clamping Elements-6

Assembly 1. Insert the guide bushing and ring piston into the housing borehole without exerting force.2. Mount the flange cover looselywithout the shim ring.3. Insert the sleeve. 4. Tighten the clamping screws atthe flange cover evenly crosswise until loss of play is indicated by stiffer sliding action of the sleeve. 5. Precisely gauge the mounting gapfor the shim ring, remove the cover.6. Adjust the high of the shim ring.Recommendation: Measured moun- ting gap + approx. 0.02 mm for contact surface compression. 7. Mount the flange cover and theunderneath shim ring, tighten thescrews crosswise.8....
