Mechanically Jointed Rodless CylinderLinear Guide TypeSeries MY1HCushion CapacityCushion SelectionRubber bumpers are a standard feature onMY1H10.Since the stroke absorption of rubberbumpers is short, when adjusting thestroke with an A unit, install an externalshock absorber.The load and speed range which can beabsorbed by a rubber bumper is inside therubber bumper limit line of the graph.Air cushions are a standard feature onmechanically jointed rodless cylinders.The air cushion mechanism isincorporated to prevent excessive impactof the piston at the stroke end during highspeed operation. The purpose of aircushion, thus, is not to decelerate thepiston near the stroke end.The ranges of load and speed that aircushions can absorb are within the aircushion limit lines shown in the graphs.Use this unit when operating with a load orspeed exceeding the air cushion limit line,or when cushioning is required outside ofthe effective air cushion stroke range dueto stroke adjustment.L unitUse this unit when the cylinder stroke isoutside of the effective air cushion rangeeven if the load and speed are within theair cushion limit line, or when the cylinderis operated in a load and speed rangeabove the air cushion limit line or belowthe L unit limit line.H unitUse this unit when the cylinder is operatedin a load and speed range above the L unitlimit line and below the H unit limit line.Caution1. Refer to the figure below whenusing the adjusting bolt toperform stroke adjustment.When the effective stroke of the shockabsorber decreases as a result of strokeadjustment, the absorption capacitydecreases dramatically. Secure theadjusting bolt at the position where itprotrudes approximately 0.5 mm fromthe shock absorber.Adjusting boltShock absorberAir Cushion StrokeBore size (mm)16202532400.52.
