HIWIN MGN7 (MGN07C/MGN07H) Miniature Linear Guide Slider
The MGN7 (including MGN07C standard block and MGN07H extended block variants) is a narrow-type miniature linear guide slider from HIWIN's MG Series, designed for seamless integration with MGNR07 profile rails (7mm width). It features a Gothic arch contact design with four-point contact, delivering balanced load capacity across radial, reverse radial, and lateral directions, plus exceptional rigidity against moment loads.
The MGN7 (including MGN07C standard block and MGN07H extended block variants) is a narrow type miniature linear guide slider from HIWIN's MG Series, designed for seamless integration with MGNR07 profile rails (7mm width). It features a Gothic arch contact design with four-point contact, delivering balanced load capacity across radial, reverse radial, and lateral directions, plus exceptional rigidity against moment loads. All steel components (block, rail, balls, retainer) are made of corrosion-resistant martensitic stainless steel as standard, making it ideal for compact precision applications in harsh or clean environments. The ball retainer design prevents balls from dislodging during rail separation, enabling safe and easy assembly.
