This M3-15T crossed helical gear, also known as skew gear, is specially developed for power transmission between non-parallel and non-intersecting shafts, with 90° shaft layout as the most common application. Adopting a standard 20° pressure angle, it supports customizable helix angle and hand of helix. The precise tooth structure enables smooth meshing and quiet operation, ideal for various light-duty working scenarios.
Featured with Type B single hub, it comes with finished bore, keyway and set screw holes, enabling firm positioning and effortless installation. Reliable and compact, this gear is extensively applied in automated facilities, packaging machines and various small industrial transmission systems.
