SKF 718909 Locknut Impact Spanner Wrench 150-190mm

SKF 718909 TMFN 23-30 is a heavy‑duty hook‑style impact spanner designed to drive SKF locknuts in bearing applications without marring the nut face. It accepts locknut diameters from 150 to 190 mm and is part of SKF's TMFN series, featuring a 319 mm overall length and a robust spheroidal cast‑iron head with a phosphated finish and a galvanized steel handle for corrosion resistance. The hook design concentrates impact energy into the nut, enabling efficient mounting and dismounting in tight spaces and reducing risk of nut damage, such as when working with SKF locknuts inside split pillow block housings (SNL). Typical uses include installing or removing locknuts on bearing housings, adapters, and sleeves in maintenance or repair scenarios where air impact or manual tooling would be impractical. With its 150–190 mm capacity, 319 mm reach, and purpose‑built geometry, the 718909 TMFN 23-30 provides a reliable, energy‑transmitting solution for service technicians handling SKF bearing assemblies.
