FO2, FO3, FO4 How to Order The model number for all FO2, FO3, and FO4 Series Flat-1 cylinders consists of three alphanumeric clusters. These designate type, bore size and stroke length, and mounting and special options. Please refer to the charts below for our example of Model Number FO2-501-3M. This is a 2-1/2" bore FO2 Series Flat-1 with 1" stroke, threaded mounting holes in both ends, with the magnetic position sensing option. FO2-501-3 M OPTIONS (Enter in alphabetical order, except EE which is last) FO2 - 2 Stage Extend, Single Stage Retract FO3 - 3 Stage Extend, Single Stage Retract FO4 - 4 Stage Extend, Single Stage Retract TYPE BORE SIZE STROKE LENGTH 0.25 - 1/4" 1 - 1" ETC. 50 - 2-1/2" 70 - 3" 125 - 4" MOUNTING OPTIONS (Enter in numeric order) No Number - Basic model (Standard counter- bored mounting holes) 3 - Threaded mounting holes, both ends 3F - Threaded mounting holes, front 3R - Threaded mounting holes, rear 4 - Screw clearance holes, both ends 1 4F - Screw clearance holes, front 1 4R - Screw clearance holes, rear 1 "Screw clearance" to allow bolt head to pass through; no counter bores. CFT - Coarse female thread (fine thread standard) CMT - Male rod end (coarse thread) G - Magnalube G L - Low friction seals M, M1, M3, M4 - Magnetic position sensing 1 MT - Male rod end (fine thread) NT - Non-threaded rod P2, P3, P4 - Front port position #2, etc. P6, P7, P8 - Rear port position #6, etc. Q - Low temperature option (-40 F to 200 F) T1, T3, T4 - Additional switch mounting post located in position #1, 3 or 4 V - High temperature option (0F to 400 F) W - Rod wiper (Buna N only) Y - Moly-coat (MoS 2 I. D. coating) EE0.375 - 3/8" extra rod extension, etc. EE1 - 1" extra rod extension, etc. 1 If magnetic position sensing is specified with option V, standard Buna-N based magnet will be provided. Magnetic position sensing is not reliable above 200 F. Approximate Power Factors Power Factor Extension Bore Model Power Factor Bore Designator Retraction FO2 FO3 FO4 2-1/2" (50) 50 9.4 13.8 18.3 4.5 3" (70) 70 13.5 20.0 26.5 6.5 4" (125) 125 24.3 36.1 47.9 11.8 Multiply the air line pressure by the power factor to get the approximate force. For example, an FO2-501-3 operated at 80 PSI will exert a force of 752 lbs. on extension, and 360 lbs. on retraction.
