Refer to each graph regarding the maximum allowable moment and maximum allowable load for a particular piston speed. Maximum allowable moment Select the moment from within the range of operating limits shown in the graphs. Note that the maximum allowable load value may sometimes be exceeded even within the operating limits shown in the graphs. Therefore, also check the allowable load for the selected conditions. Design precautions We recommend installing an external shock absorber when the cylinder is combined with another guide (connection with floating bracket, etc.) and the maximum allowable load is exceeded, or when the operating speed is 00 to 0mm/s for bore sizes ø, ø, ø, ø and ø0. oad (kg) m₁ Moment (N m) m₂ m₃ ₁ M₁ = ₁ x ₁ ₂ M₂ = ₂ x ₂ ₃ M₃ = ₃ x ₃ ₁ ₂ ₃ Maximum allowable load <alculation of guide load factor>. Maximum allowable load (), static moment (), and dynamic moment (at the time of impact with stopper) () must be examined for the selection calculations. To evaluate, use υa (average speed) for () and (), and υ (impact speed υ =.υa) for (). alculate m max for () from the maximum allowable load graph (m₁, m₂, m₃) and Mmax for () and () from the maximum allowable moment graph (M₁, M₂, M₃). Select the load from within the range of limits shown in the graphs. Note that the maximum allowable moment value may sometimes be exceeded even within the operating limits shown in the graphs. Therefore, also check the allowable moment for the selected conditions.

Note ) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper). Note ) Depending on the shape of the work piece, multiple moments may occur. When this happens, the sum of the load factors (Σα) is the total of all such moments.. Reference formulae [Dynamic moment at impact] Use the following formulae to calculate dynamic moment when taking stopper impact into consideration. m : oad mass (kg) υ : Impact speed (mm/s) : oad (N) ₁ : Distance to the load's center of gravity (m) : oad equivalent to impact (at impact with stopper) (N) M: Dynamic moment (N m) υa : verage speed (mm/s) g : ravitational acceleration (.m/s²) M : Static moment (N m) υ.

8 Series MY ushion apacity ushion selection <Rubber bumper> Rubber bumpers are a standard feature on MY. Since the stroke absorption of rubber bumpers is short, when adjusting the stroke with an unit, install an external shock absorber. <ir cushion> ir cushions are a standard feature on mechanically jointed rodless cylinders. (xcept ø.) The air cushion mechanism is installed to avoid excessive impact of the piston at the stroke end during high speed operation. The air cushion does not act 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. < 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 necessary because the cylinder stroke is outside of the effective air cushion stroke range due to stroke adjustment. unit Use this unit when cushioning is necessary 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 and below the unit limit line. unit Use this unit when the cylinder is operated in a load and speed range above the unit limit line and below the unit limit line. bsorption capacity of rubber bumper, air cushion and stroke adjusting units MY Impact speed mm/s Impact speed mm/s orizontal impact: P = 0.MPa MY Rubber bumper m max. m max. oad weight kg 0 m max. m max. oad weight kg orizontal impact: P = 0.MPa ir cushion unit m max. m max.

When the stroke adjusting unit is fixed in an intermediate position, slippage can occur depending on the amount of energy released at the time of an impact. In this case, we recommend using the adjusting bolt mounting brackets available with order made specifications -X and -X. (xcept ø.) or other lengths, consult P/. (Refer to " adjustment unit holding bolt tightening torque".) < adjustment with adjusting bolt> oosen the adjusting bolt lock nut, and adjust the stroke from the lock plate side using a hexagon wrench. Re-tighten the lock nut. < adjustment with shock absorber> oosen the two lock plate holding bolts, turn the shock absorber and adjust the stroke. Then, uniformly tighten the lock plate holding bolts to secure the shock absorber. Take care not to over-tighten the holding bolts. (xcept ø unit.) (Refer to " adjusting unit lock plate holding bolt tightening torque".) Note) Slight bending may occur in the lock plate due to tightening of the lock plate holding bolts. This is not a problem for the shock absorber and locking function.
