Why you need this linear shaft kit Delivers precise, lowfriction linear motion that reduces vibration and wear, improving repeatability for machines and fixtures. Simplifies installation and alignment with complete hardware: shafts, bearing blocks, and support units ready for mounting. Durable construction minimizes maintenance and replacement costs in demanding environments. What's included Linear shafts in diameters of 8 mm, 10 mm, 12 mm, and 16 mm with lengths from 300 mm to 800 mm to match your design requirements. 4 SCS UU bearing blocks for smooth, lowfriction, quiet operation that supports accurate linear travel. 4 SK support units that securely mount the shafts and maintain reliable alignment during use. Shafts made from hardened steel for longterm wear resistance. Key features and benefits Function: Provides controlled linear guidance for sliding components, reducing backlash and improving positional accuracy. Compatibility: Works with standard SCS UU bearing blocks and SK support configurations; suitable for integration into existing linear motion assemblies. Size options: Multiple diameters and lengths let you pick the stiffness and travel range needed for your application. Material and performance: Hardened steel shafts resist wear and maintain straightness under load; bearing blocks deliver quiet, lowfriction movement. Typical applications 3D printers and CNC routers: Improve axis accuracy and reduce vibration for better surface finish and dimensional control. Robotics and pickandplace equipment: Provide repeatable linear motion for endeffector positioning and small payload handling. Camera sliders, inspection stages, and lab automation: Smooth, quiet travel for imaging, metrology, and precise sample handling. Installation tips Choose shaft diameter and length based on load, span, and required stiffness. Secure SK support units at both ends for alignment; use the SCS UU bearing blocks to mount moving assemblies. Periodic lubrication will extend service life and maintain quiet operation.
