Mechanically Jointed Rodless CylinderBasic TypeSeries MY1BCushion CapacityCushion SelectionAbsorption Capacity of Rubber Bumper, Air Cushion and Stroke Adjusting UnitsRubber 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. Securethe adjusting bolt at the position whereit protrudes approximately 0.5 mm fromthe shock absorber.Adjusting boltShock absorber0.52. Do not use a shock absorber togetherwith air cushion.MY1B10Collision speed mm/s Collision speed mm/sMY1B20Collision speed mm/s200015001000500400300200100MY1B25Collision speed mm/s200015001000500400300200200015001000500400300200100Horizontal collision: P = 0.5 MPa100801000.50.05 0.1 0.2 0.3 0.4 0.5 1 2 3 4 5 10m3 max. m2 max. m1 max.Load mass kgHorizontal collision: P = 0.5 MPa200015001000500400300200MY1B16Horizontal collision: P = 0.5 MPa1 2 3 4 5 10 20 30 40 50m3 max. m2 max.Load mass kgLoad mass kgH unitL unitAir cushionm1 max.1 2 3 4 5 10 20 30m2.m3 max.Rubber bumperAir cushion1 2 3 4 5 10 20 30m3 max. m2 max.Load mass kgHorizontal collision: P = 0.5 MPaL unitAir cushionH unitm1 max.H unit40 50m1 max.MY1B32Collision speed mm/s2000150010005004003002001001 2 3 4 5 10 20 30MY1B40Collision speed mm/s2000150010005004003002001002 3 4 5 10 20 50MY1B50Collision speed mm/s200015001000500400300200m2 max.Horizontal collision: P = 0.5 MPam2 max.Load mass kgHorizontal collision: P = 0.5 MPam3 max.Load mass kgm3 max.1002 3 5 10 20 30 50MY1B63Collision speed mm/s200015001000500400300200Air cushionm2 max. m3 max.Load mass kg40 50m1 max.H unitL unitAir cushionm1 max.H unitL unitHorizontal collision: P = 0.5 MPaAir cushion100m1 max.Horizontal collision: P = 0.5 MPaAir cushion1002 3 5 10 20 30 50 100m2 max. m3 max. m1 max.Load mass kg959MY1BMY1MMY1CMY1HMY1HTMY1WMY2CMY2HMY3AMY3BMY3MD--XIndividual-XTechnicaldata
