Top mounting with four cylinder screws (resistance min. 12.9), these are included in the supply scope. Pistons and bolts from from hardened steel, tempered, ground and nitrided. All parts nickel plated. Supply scope includes hinge pins and tension plates, but not clamping levers. Oil supply via threaded port or oil channel in fixture body. Application: The lever-type clamping fixture is used in clamping devices where workpieces need to be freely accessible and must be placed in from above. Particularly well suited for clamping in clamping pockets. Good corrosion resistance and high surface hardness (approx. 615 HV) is provided by chemical nickel plating (specifications MIL-C-2607 AE, ASTM B733 and AMS 2404D). Features: Top flange version, lever mechanism can be turned in the range of 180º in 90º steps. Special designs are possible. Note: Proximity switch and electrical pressure-point monitoring can be supplied on request. Dimensions: Order no. Article no.
