STANDARD CYLINDERS

BACK-TO-BACK: TYPES ABB, CBB & EBB Units consist of two separate single ended Cylinders, joined together by a common rear head. Their strokes can be either identical or different. By fastening one rod end to a fixed object, these units can perform as 3 and 4 position Cylinders. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”. NOTE: Options must be indicated for each stroke.

TYPE A SINGLE ENDED : All Type “A” Cylinders, with the exception of the 4” bore, are constructed using "O"- Ring Seals. The 4” bore uses “O”- Ring Rod Seals and “U”- Cup Piston seals. These all-purpose units are used for most pneumatic applications. Optional Double Rod Packings are recommended for heavy-duty and hydraulic applications, not available on 7/8” & 1-1/8" Bores. Pressure Rating: 150 P.S.I. Pneumatic, 350 P.S.I. Hydraulic. Breakaway: Approximately 5 to 8 P.S.I. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2” ,3” & 4" .

TYPE E SINGLE ENDED : Type “E” Cylinders are constructed using Block-Vee Seals and include double rod seals in the front head except on the 7/8” & 1-1/8” Bores. A heavy-duty wear strip (bearing) on the piston minimizes friction and piston seal wear, and side load conditions prevents metal-to-metal contact. These Cylinders are generally used on low pressure hydraulics and where side load conditions are present. Pressure Rating: 200 P.S.I. Pneumatic, 500 P.S.I. Hydraulic. Breakaway: Approximately 10 to 15 P.S.I. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3”, 4” & 5*. *5” BORE AVAILABLE-Consult Factory for Details.

TYPE C SINGLE ENDED : Type “C” Cylinders are constructed using low friction "U" Cup Seals and include a wear strip on the piston with the exception of the 4" bore (it has no wear strip). These Cylinders are primarily used on low pressure applications and where low minimum breakaway is required. Pressure Rating: 150 P.S.I. Pneumatic only. Breakaway: Approximately 2 to 3 P.S.I. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2” & 3" .

DOUBLE ENDED: TYPES AD, CD & ED Cylinders are constructed with a common single rod, which protrudes from both ends. As one end retracts, the other extends. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”. Maximum Stroke Available: 65”. NOTE: Due to piston construction, 3/32” of stroke is lost on Type AD 1-1/2”, 2”, 2-1/2” and 3” bore sizes. DOUBLE ENDED: TYPES AD, CD & ED Cylinders are constructed with a common single rod, which protrudes from both ends. As one end retracts, the other extends. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”. Maximum Stroke Available: 65”. NOTE: Due to piston construction, 3/32” of stroke is lost on Type AD 1-1/2”, 2”, 2-1/2” and 3” bore sizes.

INTEGRAL REAR SWIVEL: TYPES AN, CN & EN Cylinders are constructed with a female clevis end, including clevis pin. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”.

INTEGRAL SQUARE HEAD: TYPES AS, CS & ES TYPES ASD, CSD & ESD Units incorporate the use of square heads, thus eliminating the need for separate Foot Mounts. Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2” & 2”. NOTE: Due to piston construction, 3/32” of stroke is lost on Type ASD 1-1/2” and 2” bore sizes.

NON-ROTATING: TYPE: AR, ARD The Piston Rod Assembly of conventional double acting air and hydraulic cylinder will rotate a few degrees with each operation of the cylinder. Where this is objectionable and where the piston rod cannot be guided externally, A NON-ROTATING CYLINDER should be used. ALLENAIR TYPES "AR" and "ARD" CYLINDERS are built with two (2) guide rods extending between cylinder heads and thru piston guide rod bearings. This prevents piston rod rotation completely. Service life of these cylinders is excellent, in no way different from our conventional construction. All other construction features are the same as our standard cylinders. BORE SIZES: 2", 3" and 4" STROKES: Same as for other Allenair Cylinders up to 20" Maximum.

Available for pneumatic (TDP) and hydraulic (TDH) service. The TD Option gives you an internal Linear Resistive Transducer (LRT) for extremely accurate piston position sensing . It is ideal for applications where magnetic Reed and Hall effect switches are not acceptable. The TD Option is the perfect solution for applications where variations in cylinder stroke and speed are required or where an application calls for real time position monitoring. Offered in bore sizes from 1-1/8" to 4" and strokes up to 18". Cylinder comes standard with an IP 67 rated 8mm 3 pin male cable connector. TDH and TDP Standard cylinder construction differs depending on bore size, for instance 1-1/8” and 1-1/2” bore sizes have an aluminum threaded rear head with an aluminum snap-ring construction front head the 2” thru 4” bore have our traditional Snap-Ring construction front and rear. All bore sizes utilize stainless steel cylinder tubing with the exception of the 4” bore which uses heavy wall brass tubing. TDP Type “C” Cylinders are constructed using low friction “U”- Cup Seals and include a wear strip on the piston. These Cylinders are primarily used on low pressure app

TANDEM: TYPE: ET SINGLE ENDED TYPE: ETD DOUBLE ENDED The basic construction of these Cylinders is identical to Type “E” and feature two Cylinders in tandem having two pistons mounted on one common rod. Pneumatic operation with hydraulic control can be obtained by operating the rear Cylinder pneumatically and filling the front Cylinder with oil and piping its ports in series using a flow control valve. The output force of a single Cylinder can be almost doubled using a Tandem Cylinder and piping both rear ports together and both front ports together, which will apply the working pressure to both Cylinders at the same time. This is particularly useful when space limitations preclude the use of large bore Cylinders, and the force required is greater than that supplied by smaller bore units. Bore Sizes Available: 1-1/2", 2", 2-1/2", 3" & 4”. Maximum Stroke Available: Type "ET"      : 60”. TType "ETD" : 40”.

THREE POSITION: TYPES: AP, CP & EP SINGLE ENDED TYPES: APD, CPD & EPD DOUBLE ENDED Cylinders feature two separate piston rod assemblies which provide three definite and positive positions. Any combination of first stroke and total stroke is available. Both rods fully retracted are first position. Port #1 Extends rod first stroke to second position. Port #2 Extends rod full stroke to third position. Port #3 Retracts both rods to first position. When ordering, second stroke must be specified as total stroke, as second Cylinder rod moves through both strokes. For example, if first stroke required is 4” and second stroke is 2”, order should read: AP- 3 X 4 X 6.  6” being the total stroke (4+2). Bore Sizes Available: 1-1/2”, 2”, 2-1/2”, 3” & 4”. NOTE: Options must be indicated for each stroke.
