SMC offers these parallel grippers in three stroke variants, each with six different piston diameters of 10, 16, 20, 25, 32 and 40 mm. Their strokes range from 20 to 200 mm. Thanks to a modified groove shape on the housing of the MHL2 parallel grippers, the D-M9 series limit switches can be integrated directly if required. Tools and fastening elements are not required. In order to be able to react as flexibly as possible to different installation situations, four grooves are available.

Depending on the model, up to 10 percent weight has been saved during the revision of the series. Numerous options, such as a dust-protected version or the choice of opening or closing stroke, make it possible to tailor the parallel grippers precisely to the specific requirements of an application. All models are already equipped with improved dust protection as standard. To reliably prevent the ingress of microparticles down to 10 µm, the parallel grippers can be ordered with an optional double dirt wiper. On all models, a dirt wiper ensures that a homogeneous lubricating film can constantly protect the surface. This is one of many prerequisites for a long service life. NBR and fluororubber are available as seal materials.

Double piston grips powerfully

On both sides of the parallel grippers, oil-impregnated plastic guides with metal seals on the piston rods ensure particularly smooth running. The grippers in the MHL2 series, on the other hand, are able to grip powerfully when it counts. This is ensured by a double piston inside, which generates an excellent holding force. The fingers of the gripper are synchronized using a special rack and pinion mechanism.

Many options available

With numerous ordering options, SMC offers the possibility to configure the pneumatic parallel grippers of the MHL2 series to fit perfectly. In addition to the standard housing, a heat-resistant cylinder for applications up to 100 °C is also available. Fluorocarbon rubber or EPDM can be selected as the sealing material. For users in the food industry, variants with fluorine grease or aluminum complex soap grease are available. In the highly dust-protected version, which reliably protects against the ingress of microparticles up to 10 µm, the parallel grippers include a high-performance wiper with a stable lubrication function.
