F-Series Direct Interchange Air Cylinders 3 Specifications and prices subject to change without notice or incurring obligation Overall Length Calculations for F Series Cylinders Rod Thread Roll-formed rod threads at both ends provide strength for customer connections as well as the internal piston connection. Rod Seal Low friction Buna N “U”-cup seal is inherently wear compensating for long, trouble-free cycle life. Optional low and high temperature seals are available. Temperature Ranges Standard Seals. . . . . . . . . . –10° to +165°F (–23° to + 74°C) Low Temperature Seals . . . –40° to +225°F (–40° to + 107°C) Viton ® Seals. . . . . . . . . . . . –15° to +350°F (–26° to + 177°C) Stroke Tolerance = +/– .032 Piston Rod 303 stainless steel, ground, polished, and roller burnished for corrosion-free long life. End Caps High strength aluminum. Rod Bushing Oil impregnated sintered bronze for excellent wear and long life. Tube Thin wall 304 stainless steel, drawn and polished for low friction and long life. Piston Seals Low friction Buna N “U”-cups are inherently wear compensating for long, trouble-free cycle life. Crimp Cylinder body tube and end caps are attached with double rolled-in crimp. Magnet Piston position indication with reed or electronic sensors. See individual cylinder drawings for length adjustments. See page 62 for sensors. Piston High strength aluminum in all units. Double acting units include air passage to the entire piston and seal area for quick response and full force performance. Ports Full-flow ports and cross-slots on the end caps allow air passage to the entire piston and seal area for quick response and full force performance. Pre-Lubrication Factory lube is a special petroleum based oil formulated for long maintenance-free performance. Single acting F-Series cylinders have stop tubes added for every 1/2" or 1" depending on the bore size. Strokes with no fractional inch simplify the calculation of having a base length plus adder per inch of stroke. However, strokes with fractional inch require more in-depth calculation. The following equations help to calculate the OAL for fractional inch strokes. Variables : OAL = Overall Length of Cylinder S = Actual Stroke B = Base Length STA = Stop Tube Adder per increment of stroke S1 = Stroke rounded up to the next increment (5/16" and 7/16" bores have 1/2" increments) Note: for 2" bores – use lengths shown on page 34 for whole inch strokes and subtract the difference between desired stroke and next longer standard increment. (Subtract twice for spring extend models.) Single Acting Spring Return Cylinders Calculate the length of next whole standard increment of stroke. Then subtract the difference between desired stroke and next longer standard increment of stroke. OAL = B + (STA x S1) – (S1 – S) Example : F-1062S01-02M (2-3/4" stroke) F-1062S01 base length = 1.938 Plus 1.562 per inch of stroke = +4.686 1.562 x 3.0 (next longer stroke increment) F-1062S01-03A length = 6.624 Standard stroke increment = 3.000" minus desired stroke = –2.750 Stroke difference = .250 –.250 F-1062S01-02M length = 6.374 Double Acting Cylinders Add desired stroke length to base length of cylinder. OAL = B + S Example : F-0750D01-01E (1-1/4" stroke) F-0750D01 base length = 2.969 Plus 1.250 stroke = +1.250 F-0750D01-01E = 4.219 Single Acting Spring Extend Cylinders Calculate the length of next whole standard increment of stroke. Then subtract twice the difference between desired stroke and next longer standard increment of stroke. OAL = B + (STA x S1) – 2(S1 – S) Example : F-0438R02-01K (1-5/8" stroke) F-0438R02 base length = 2.375 Plus 1.438 per each 0.5" stroke = +5.752 1.438 x 4.0 (number of standard increments required for the next longer increment) F-0438R02-02A length = 8.127 Standard stroke increment = 2.000" minus desired stroke = –1.625 Stroke difference = .375 Twice stroke difference = .750 –.750 F-0438R02-01K length = 7.377 10-2-12
