1 ACTUATORS ACT-04 For further information www.norgren.com Air Reservoir Air Reservoirs are made of the same high-quality stainless steel as the Series RP Cylinders. How to Order Example: 1-1/16" bore air reservoir with a 3" internal length would be ordered as follows: AR-1-1/16 x 3 EE NPT (Both Ends) E J K LB PLUS LENGTH K Dimensions in inches Bore E EE J K LB Standard Internal Lengths 3/4" 0.813 1/8" 0.625 0.187 1.938 1" increments thru 4" 1-1/16" 1.125 1/8" 0.875 0.187 2.375 1" increments thru 8" 1-1/2" 1.562 1/8" 0.875 0.250 2.250 1" increments thru 16" 2" 2.080 1/4" 1.250 0.312 2.875 1" increments thru 16" 2-1/2" 2.610 1/4" 1.750 0.312 2.875 1" increments thru 24" 3" 3.12 3/8" 2.00 0.312 3.188 1" increments thru 24" Bore Code Force Factor (Area) Extend Retract 5/16" (031) 0.077 0.064 7/16" (043) 0.15 0.12 9/16" (056) 0.25 0.22 3/4" (075) 0.44 0.39 7/8" (087) 0.6 0.55 1-1/16" (106) 0.89 0.81 1-1/4" (125) 1.23 1.08 1-1/2" (150) 1.77 1.62 1-3/4" (175) 2.41 2.21 2" (200) 3.14 2.84 2-1/2" (250) 4.91 4.61 3" (300) 7.07 6.63 Force Output Formula Cylinder Output Force = Force Factor (area) x Air Line Pressure (psi) Ex: 1-1/16 bore cylinder operating at 80 psi: Force exerted on the extend: 0.89 x 80 = 71.2 lbs. Force exerted on the retract: 0.81 x 80 = 55.2 lbs.

Single Acting Cylinders To find total length of cylinder, calculate the length of next whole increment of stroke, then subtract the difference between the desired stroke and the next whole increment of stroke. Example: RP106X1.750-SAN RP106 Base Length= 1.94" Add, 1.56 per inch of stroke= 3.12" (1.56 x next higher stroke, 2") Total for RP106x2.000-SAN 5.06" Whole stroke Increment 2.00" Less required stroke 1.75" Stroke Difference 0.25" Subtract Stroke Diff. -0.25 RP105X1.750-SAN 4.81" Reverse Acting Cylinders To find total length of cylinder, calculate the length of next whole increment of stroke, then subtract 2 x the difference between the desired stroke and the next whole increment of stroke. Example: RP075X1.375-RAN RP075 Base Length = 2.38" Add, 2.62" per inch of stroke = 5.34" (2.62 x next higher stroke, 2") Total for RP075x2.000-RAN 7.72" Next whole stroke increment 2.000" Less required stroke -1.375 Stroke Difference 0.625" 2 x stroke difference 1.250" -1.25 RP075X1.375-RAN 6.47" Roundline Plus Stainless Steel Body Actuators 5/16" to 3" bore Single and Double acting actuators
