Applications
\nThe SL-HM Hydraulic Nutis specially designed for slitting line applications and is suitable for:
\nAxial locking of cutter shafts on metal slitting machines.
\nLocking of tool holders on rotary shears.
\nLocking of cutter holders.
\nFastening of tools, fixtures, and clamping devices on forming shafts.
\nClamping and fastening fixtures used in forming operations.
\nFastening of other shaft-mounted tools and fixtures.
\nWorking Principle
\nThe SL-HM Hydraulic Nutis a high-performance hydraulic locking device developed for slitting machine applications.
\nIts operating principle is simple: a T-handleis used to rotate the pressure screw, which pushes the pressure pistoninward. This increases the pressure of the sealed hydraulic medium, causing the annular pistonto extend and generate axial clamping force for locking rotating tools such as spacers, cutters, and other shaft-mounted components.
\nThe operator can simultaneously check the scale on the thrust indicatorto confirm whether the required clamping force has been reached.
\nAdvantages of the SL-HM Hydraulic Locking Nut
\nThe main body is manufactured from chrome-molybdenum steel, providing high strength and durability. The surface features knurling and black oxide treatment. Its lightweight design and dedicated operating wrench allow convenient installation and removal.
\nProvides high axial clamping force to securely lock slitting blades without deformation under axial pressure.
\nHelps reduce blade wear, extend blade service life, shorten blade-setting time, improve machine utilization, and minimize burr formation on slit material.
\nNo external oil filling is required. Axial clamping force remains stable, with reliable sealing and no oil leakage.
\nSealed grease-type design requires no external pressure release.
\nRequires only a small amount of grease for optimum performance, providing clean and environmentally friendly operation.
\nCustom special-shaped hydraulic nuts and threadless hydraulic nutsare available according to customer requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"
