MAINTENANCE INSTRUCTIONS
DISASSEMBLY, HEAD END
Remove any plumbing from cylinder ports; wrap barrel in heavy cloth to prevent damage to barrel. Place cap end of cylinder barrelin vise. As you rotate head counter-clockwise, use a screw driver to lift end of circumflex key clear of slot (Fig. 1).
Continue rotation of head, and circumflex key will feed out of slot (Fig. 2). Gripping rod, pull forward. Head, rod and piston will come out of barrel(Fig. 4). Screw head off rod threads for ease of clearing rod packing.
CAP END
Slide head end back in barrelto support barreland follow same procedure as above to remove circumflex key from cap end (Fig. 3). If cylinder has been used in wet or moist external conditions for a long period, circumflex key may be corroded. If this is the case, apply penetrating oil into the lock slots prior to disassembly.
ASSEMBLY
Replace piston (if necessary), rod packings and wiper and all static seals. Clean I.D. of tube thoroughly. Lubricate rod packings and O.D. of piston prior to assembly. To reassemble cylinder, follow above procedure, except heads will be turned clockwise after circumflex key is engaged in tang hole in circumflex groove of head. Turn clockwise until circumflex is completely into groove and cylinder port in head is aligned with port hole in barrel. To get head end over rod threads without damaging packing and wiper, wrap rod threads with tape.
NOTE: Lock nut must be replaced when piston is replaced (Fig. 4). Do not use old lock nut. Complete packing kits and lubricants are available for all Flairline cylinders and can be ordered from your Flairline distributor.
TIPS
Applications for pneumatic cylinders are limitless. Application assistance is available from your local Flairline distributor or from the many publications that are readily available throughout the fluid power industry. Pictured below are some typical pneumatic cylinder applications.
FLAIRLINE HI-CYCLE CYLINDERS
WARNING
Flairline’s Series F ‘uni-piston’ should not be used in heavy sideload applications. When using an all rubber piston, it is possible for sideloading to cause a “jamming” condition. This will result in delayed actuation of the cylinder.
When sideloading is necessary, contact your local Flairline distributor or the factory for alternative piston configurations.
Flairline will not assume responsibility for the application of its products.
NOTE: All specifications and dimensions are subject to change without notice.

THE TIE RODS ARE MISSING
the tie rods means
mounting, lighter weight and easy maintenance. Flairline heavy duty features provide millions of trouble-free cycles less expensively than equivalent tie rod cylinders.
Chrome-plated, high-strength, steel piston rods are corrosion resistant, rugged and durable. Three NFPA rod end options are offered. Optional stainless steel is available upon request.
High-quality elastomer rod wiper protects rod seal by preventing contaminants from entering cylinder during retract stroke. Resilient synthetic rubber will not scratch rod.
Pressure-energized, U-cup type rod seal is wear compensating, low friction and provides positive sealing.
Lightweight aluminum heads and caps
long corrosion-resistant life.
Extra-long, low-friction nylon rod bearing ‘gives’ rather than wears under normal side loading. When necessary, service is easy; only the bearing is replaced, not the head.
Heads and caps are held to tube by
of a circumflex key. The large square steel locking device requires no special installation tools. Service to head or cap can be done without disassembling the entire cylinder.
Adjustable cushions, available on 2” bore and larger, are flush with the O.D. of the cylinder. The 11/2” bore has fixed cushions.
Flairline
lubricated
Cushion seal “check valve” offers fast break-away, self-aligning, positive cushioning for faster stroking and reduced cylinder wear.
Precision-drawn, lightweight aluminum barrels are hard-anodized inside and out for corrosion and abrasion resistance. Fine I.D. microfinish provides long life and positive sealing.

NFPA
FLAIRLINE HI-CYCLE SERIES FI, OI AND OILF
Flairline double-acting NFPA interchangeable cylinders can be used in nearly all applications where lightweight, economical, long-service actuators are required. Operating systems can be pneumatic or hydraulic. Low friction, pneumatic service is available with Series OILF which is designed primarily for use on low pressure applications and where low minimum breakaway is required. See page 23 for dimensional data, pages 24 and 25 for mounting styles, page 25 for rod end styles and page 26 for accessories. For special options, see page 28.
For ordering information, see page 29.
F TYPE PISTON
Pressure energized, wear compensating double lip type, ‘uni-piston’ seal (Buna N). Rubber bonded to a plated disc to assure positive sealing, will outlast O-rings and can never score cylinder I.D.
FI
Standard Bore Sizes – 11/2, 2, 21/2, 31/4, 4 Stroke Sizes – Any stroke up to 130” Cushions available – either/both ends Pneumatic only – 150 psi maximum

DOUBLE-ENDED CYLINDERS NFPA INTERCHANGEABLE
FLAIRLINE HI-CYCLE SERIES FIDE AND OIDE
Flairline double-acting double-ended NFPA interchangeable cylinders feature piston rod extensions from each end and a choice of F or O type pistons. As one end is extended, the opposite end is retracted. Working range (stroke), force and speed are equal in both directions so work can be accomplished at both ends simultaneously. See page 23 for dimensional data, pages 24 and 25 for mounting styles, page 25 for rod end styles and page 26 for accessories. For special options, see page 28.

FLAIRLINE HI-CYCLE SERIES FINR, OINR AND OIMNR
Series FINR, OINR and OIMNR are dimensionally interchangeable with Flairline Series FI and Series OI NFPA cylinders except for the non-rotating feature consisting of two external chrome-plated steel guide rods, guide flange (MF1) and steel rod end mounting block. Flairline double-acting non-rotating cylinders feature a choice of F type pistons (Series FINR), O type pistons (Series OINR) or OIM type pistons (Series OIMNR). Series OIMNR provides magnetic switch service. See page 8 for magnetic switch options including Reed and Hall Effect types. See page 23 for dimensional data, pages 24 and 25 for mounting styles and page 26 for accessories. For special options, see page 28.

Alignment couplers improve bearing and seal life by preventing excessive binding and friction caused by misalignment. Flairline alignment couplers also allow greater assembly tolerances than would typically be required which help simplify cylinder installation. Alignment couplers work equally well in “push” or “pull” applications and are available for all Flairline cylinders.

VALVES
Lightweight aluminum O-Check® features a dilating O-ring as the only moving part. Quick to open, quick to close, O-Check ‘outflows’ the competition, will last millions of cycles (factory tests to 50 million cycles show no discernible wear) and always provides positive sealing (no bubble leakage). Standard NPTF sizes 1/8”, 1/4”, 3/8”, 1/2” and 3/4”and orifices available for fixed flow control applications.
Model No. Pipe Thread
FLOW CONTROLS
Flairline right angle flow controls incorporate O-Check as the bypass valve. RFC permits full free flow in one direction, accurately metered flow in opposite direction. Standard metering needle design includes compound needle taper of 5• and 15• and fine adjustment stem threads (RFC 1/4 for example is 1/4”-36). Right angle design eliminates the need for pipe ell normally used to make 90• turn at cylinder port. Standard NPTF sizes 1/8”, 1/4”, 3/8”, 1/2” and 3/4”. Adjustment knobs and panel mounting available (NPTF sizes 1/8”, 1/4” and 3/8” only). Optional swivel connector allows “direct” cylinder mounting and 360• rotation for ease of installation and space saving (NPTF sizes 1/8”, 1/4”, 3/8”, and 1/2” only).
