Magnetically Coupled Rodless Cylinder New ø6, ø10, ø15, ø20, ø25, ø32, ø40 Weight 15 % reduced RoHS Overall length 15 mm shortened Max. Max. 0.96 kg (Existing model 1.13 kg) 240 mm (Existing model 255 mm) (CY1S 15-100 stroke) (CY1S 40-100 stroke) Reduced in length Improved durability Lub-retainers are mounted on the internal and external surfaces of the cylinder tube to maintain the lubrication. External surface lub-retainers Cylinder tube Adjustment bolt improves stroke accuracy/repeatability. Stroke position can be maintained with the adjustment bolt positioned next to the shock absorber, so stroke adjustment is not necessary. Adjustment bolt Internal surface lub-retainers Series CY1S Shock absorber CAT.ES20-227A

Model Selection Series CY1S 3 — e Consideration of guide load factor Work load mass and allowable moment varies depending on the load mounting method, stroke, cylinder mounting orientation and piston speed. Whether the cylinder is suitable or not is decided by the allowable load mass on guides in the graphs. The selection calculation is shown below. It is necessary to consider i) allowable load mass on guides, ii) static moment and iii) dynamic moment (when the slide block collides with the stopper). i) · ii) is calculated with Va (average speed) and iii) is calculated with V (collision...

Series CY1S Calculation of Guide Load Factor The selection calculation finds the load factors ( n) of the items below, where the total does not exceed 1. Load factor n Item Note 1: Maximum load mass 1 = m/mmax Examine m. mmax is the max. load mass for Va. 2: Static moment 2 = M/Mmax Examine M1, M2, M3. Mmax is the allowable moment for Va. 3: Dynamic moment 3 = ME/MEmax Examine M1E, M3E. MEmax is the allowable moment for V.
