Makers, 3D printer builders, and CNC hobbyists who demand consistent, low-friction motion need a bearing wheel engineered specifically for V-slot and V-groove rail profiles — not a generic round bearing pressed into service.\u003c\/p\u003e\n\u003cp\u003eThe V625ZZ is a dedicated V groove guide pulley bearing machined from bearing steel with double metal shields (ZZ) for dust and debris resistance. It measures 5mm bore × 22mm outer diameter × 5mm width (approximately 0.20\" × 0.87\" × 0.20\"), with a precision-ground V groove profile on the outer race designed to seat flush against V-slot aluminum extrusion and similar rail systems.\u003c\/p\u003e\n\u003cp\u003eTypical applications include 3D printer X\/Y\/Z axis carriage wheels, CNC router gantry guide rollers, laser engraver linear motion assemblies, and custom DIY automation rigs where a compact, low-profile bearing wheel is required to track along V-groove extrusion rails.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard V-slot aluminum extrusion rails (20×20, 20×40, 40×40 profiles).
