3 Offers excellent dust and water resistance In environments where the cylinder is exposed to dust particles and water spray or splash, its dustproof, water-resistant cover offers superior protection. Side seals provide greater lateral dustproofing and water resistance. Side seal The cover in no way interferes with the installation of base cylinder options. Cover units and Side seal units can be installed on the already existing Series MYM/MYC. Which have thenew type end caps with pre-tapped holes. Protective cover only minimally adds to overall length. ase cylinder ase cylinder + to 0mm Water-resistant solid state switches can be mounted onto the ø to ø models. Stroke availability Strokes may be selected in increments of mm. Stroke adjusting unit Strokes can be adjusted either at one end or both ends. With adjusting bolts With low load shock absorber + djusting bolts ( unit) Centralized piping Piping ports are concentrated on one side. Side supports Side supports prevent cylinder tube from sagging in long stroke applications. Interchangeable mounting Cylinder and work piece mounting interchangeability is possible between Series MYMW and MYCW. Features

In such cases, install a side support at the intermediate stroke position. The spacing of the side support must be no more than the values shown in the graphs at right. m. If the cylinder mounting surfaces are not measured accurately, using a side support may cause poor operation. Make sure to level the cylinder tube when mounting the cylinder. For long stroke operation involving vibration and impact, the use of side supports is recommended even if the spacing value is within the allowable limits shown in the graphs.. Support brackets are not for mounting. They should be used only to provide support. 9 l m m l Caution l l MYMW Weight m (kg) (00) (800) (0) (00) (00) (000) (900) MYMW MYMW MYMW MYMW MYMW MYMW MYMW MYMW MYMW MYMW MYMW Support spacing l (mm) MYCW Weight m (kg) (00) (0) (0) (000) (900) (0) (00) MYCW MYCW MYCW MYCW MYCW MYCW MYCW MYCW MYCW MYCW MYCW MYCW Support spacing l (mm)

Install a lead wire cover following the instructions provided below to prevent the lead wire from interfering with the slider. ead wire cover is packaged together with size ø and ø cylinders equipped with auto switches. For ordering the lead wire cover separately, use the following part number: MYMGR8- (ength: m). uto switch mounting position Up to auto switches can be mounted on one side of the cylinder (total of 8 switches on both sides). When multiple auto switches are used, be sure to use the lead wire groove and pull the lead wires out from the edge of the cylinder.

How to mount auto switch/install lead wire cover. Insert and slide in the auto switch from the side of the cylinder and secure it with the screw provided. (Refer to Figure.). Cut the lead wire cover to the desired length using a cutter or tube cutter. (Refer to Figure.). First place the lead wires into the lead wire cover. Then, install a lead wire cover onto a cylinder body. (Refer to Figure.). Make sure that the lead wires do not interfere with the slide table at any stroke range.

Three factors must be considered when computing calculations for selection: a) Maximum load weight b) Static moment c) Dynamic moment (at the time of impact with stopper) To evaluate, use υa (average speed) for a and b, and υ (impact speed υ =.υa) for c. Calculate m max for () from the maximum allowable load graph (m₁, m₂, and m₃), and Mmax for () and () from the maximum allowable moment graph (M₁, M₂, and M₃). Select the load weight from within the range of limits shown in the graphs. Note that the maximum allowable moment value may sometimes exceed even the operating limits shown in the graphs.

31 Mechanically Jointed Rodless Cylinder with Protective Cover Series MY W Cushion Capacity Cushion selection bsorption capacity of air cushion and stroke adjusting units <ir cushion> ir cushions are a standard feature for mechanically jointed rodless cylinders. The air cushion mechanism is incorporated to prevent excessive impact of the piston at the stroke end during high speed operation. The purpose of air cushion, thus, is not to decelerate the piston near the stroke end. The ranges of load and speed that air cushions can absorb are within the air cushion limit lines shown in the graphs. <Stroke adjusting unit with shock absorber> Use this unit when operating with a load or speed exceeding the air cushion limit line, or when cushioning is required outside of the effective air cushion stroke range due to stroke adjustment. unit Use this unit when the cylinder stroke is outside of the effective air cushion range even if the load and speed are within the air cushion limit line, or when the cylinder is operated in a load and speed range above the air cushion limit line or below the -unit limit line. Caution. Perform stroke adjustment using the adjusting bolt as shown in the picture below. When the effective stroke of the shock absorber decreases due to stroke adjustment, the absorption capacity decreases dramatically. djust the adjusting bolt so that it is secure at a position where it protrudes approximately 0.mm beyond the shock absorber. djusting bolt Shock absorber ir cushion stroke ore size (mm) 0..
