Frequently Asked Questions
Q: What is the difference between SK and SHF linear shaft support styles?
A: SK supports are pillow-block style with a round bore and side-mounting bolt holes, making them ideal for frame-side mounting. SHF supports are flange-type with a flat mounting base and are better suited for surface or base-plate mounting. Both provide excellent shaft alignment for CNC and 3D printer applications.
Q: Which shaft diameter should I choose for my CNC router or 3D printer?
A: Select the size that matches your linear rod diameter. Common sizes include 8mm for compact 3D printers, 10mm and 12mm for mid-size CNC routers, and 16mm or 20mm for heavier-duty motion systems. Measure your existing rod or consult your machine's BOM (bill of materials) before ordering.
Q: Are these shaft supports compatible with standard linear rods and bearings?
A: Yes. These SK and SHF shaft supports are designed to the standard metric dimensions widely used in CNC, 3D printing, and automation applications and are compatible with standard chrome or hardened linear rods and LM-series linear bearings of the corresponding diameter.
