Mechanically Jointed Rodless CylinderBasic TypeSeries MY1B18Cushion CapacityCushion SelectionRubber bumpers are a standard feature onMY1B10.Since the stroke absorption of rubber bumpersis short, when adjusting the stroke withan A unit, install an external shock 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.(Except ø10.)The air cushion mechanism is incorporatedto prevent excessive impact of the pistonat the stroke end during high speedoperation. The purpose of air cushion,thus, is not to decelerate the pistonnear 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 cushioning is necessaryoutside of the effective air cushionrange even if the load and speed are withinthe air cushion limit line, or when the cylinderis operated in a load and speedrange above the air cushion limit line andbelow the 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 to performstroke adjustment.When the effective stroke of the shockabsorber decreases as a result ofstroke adjustment, the absorption capacitydecreases dramatically.

Install a protective coverto prevent direct contact with the humanbody.Adjusting boltlock nutLock plateThe unit can be secured by evenlytightening the four unit holding bolts.CautionUnit holding boltLock plateholding boltShock absorberDo not operate with the strokeadjusting unit fixed in anintermediate position.When the stroke adjusting unit is fixed inan intermediate position, slippage canoccur depending on the amount of energyreleased at the time of an impact. In suchcases, the use of the adjusting boltmounting brackets, available per made-toorderspecifications -X416 and -X417, isrecommended. (Except ø10)For other lengths, please consult withSMC (Refer to “Tightening Torque forStroke Adjusting Unit Holding Bolts”.)Loosen the adjusting bolt lock nut, andadjust the stroke from the lock plate sideusing a hexagon wrench. Retighten thelock nut.Loosen the two lock plate holding bolts,turn the shock absorber and adjust thestroke. Then, uniformly tighten the lockplate holding bolts to secure the shockabsorber.Take care not to over-tighten the holdingbolts. (Except ø10 and ø20 L unit.) (Referto “Tightening Torque for Stroke AdjustingUnit Lock Plate Holding Bolts”.)Note)Although the lock plate may slightly benddue to tightening of the lock plate holdingbolt, this does not a affect the shockabsorber and locking function.
