Series MY1MCushion CapacityCushion SelectionAir cushions are a standard feature onmechanically jointed rodless cylinders. Theair cushion mechanism is incorporated toprevent excessive impact of the piston atthe stroke end during high speedoperation. The purpose of air cushion,thus, is not to decelerate the piston nearthe stroke end. The ranges of load andspeed that air cushions can absorb arewithin the air cushion limit lines shown inthe 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.Use 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.Use 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 from theshock absorber.Adjusting boltAbsorption Capacity of Air Cushion and Stroke Adjusting UnitsMY1M16Collision speed mm/sMY1M20Collision speed mm/s200015001000500400300200100MY1M25Collision speed mm/s2000150010005004003002001000.5200015001000500400300200100Horizontal collision: P = 0.5 MPaL unitAir cushion1 2 3 4 5 10 20 30m3 max. m2 max.Load mass kgHorizontal collision: P = 0.5 MPa1 2 3 4 5 10 20 30 400 50m3 max. m2 max.Load mass kgHorizontal collision: P = 0.5 MPaL unitAir cushionm1 max.H unitL unitAir cushionm1 max.H unit1 2 3 4 5 10 20 30 40 50MY1M32Collision speed mm/s2000150010005004003002001002 3 4 5 10 20 30 40 50MY1M40Collision speed mm/s2000150010005004003002001002 3 4 5 10 20 50MY1M50Collision speed mm/s200015001000500400300200Horizontal collision: P = 0.5 MPaAir cushionm3 max. m2 max.Load mass kgHorizontal collision: P = 0.5 MPaAir cushionm3 max. m2 max.Load mass kgHorizontal collision: P = 0.5 MPaAir cushion1002 3 4 5 10 20 30 40 50H unitL unitL unitm1 max.H unitm1 max.H unitL unit1001000.5m3 max. m2 max.Load mass kgm1 max.m3 max.Load massm2 max. m1 max.kgShock absorberMY1M63Horizontal collision: P = 0.5 MPa2.
