This listing offers a 4piece lot of SHF12 linear bearing shaft supports, designed to mount and guide linear bearings along shafts in compact motion systems. Part of the SHF shaft support family, these components help keep bearings aligned and provide a stable platform for smooth, repeatable motion in 3D printer and CNC router builds. The size specified for this lot is SHF12. Key benefits Improves shaft alignment and rigidness for precise linear motion. Reduces play and vibration, contributing to better dimensional accuracy in prints and cuts. Simple integration into frames and assemblies that use SHF12 shaft supports. Precisiondesigned surfaces support consistent performance over multiple uses. Key attributes Size: SHF12 Quantity: 4 pieces per lot Type: Linear bearing shaft support Application: Suitable for 3D printers and CNC routers Material: Not specified in listing Performance: Engineered to provide stable support for linear bearings and shafts, aiding reliable, repeatable movement Use cases 3D printer axis support: reinforces X, Y, or Z axis shafts to improve print quality and axis stability. CNC router gantry: provides reliable shaft support for smooth, accurate cutting or routing. XY/XYZ stages in hobbyist or lightindustrial setups: helps maintain precise alignment in compact linear motion systems. Note: This description reflects the size SHF12 and the 4piece lot as specified. Please verify compatibility with your shaft diameter and mounting requirements before use.
