Because of the recent unavailability of Brass Tube, you may receive a stainless steel tube at no extra cost.

Air & Hydraulic Cylinders Available in Brass or Stainless Steel

BASIC CONSTRUCTION (DOUBLE ACTING)

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”, 3/4” & 1-1/8” Bores. 

Pressure Rating: 150 PSI. Pneumatic, 350 PSI. Hydraulic. 

Breakaway: Approximately 5 to 8 PSI. 

Bore Sizes Available: 7/8”, 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”.

TYPE C SINGLE ENDED

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 applications and where low minimum breakaway is required.

Pressure Rating: 150 PSI. Pneumatic only.

Breakaway: Approximately 2 to 3 PSI.

Bore Sizes Available: 7/8, 1-1/8”, 1-1/2”, 2”, 2-1/2 & 3”.

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 on 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 PSI. Pneumatic, 500 PSI. Hydraulic.

Breakaway: Approximately 10 to 15 PSI.

Bore Sizes Available: 7/8”, 1-1/8, 1-1/2”, 2”, 2-1/2”, 3” & 4”.

5” BORE AVAILABLE-Consult Factory for Details.

STANDARD VARIATIONS OF TYPES A, C & E

The basic construction of these standard variations is respectively identical to

Types “A”, “C” or “E”, except where noted.

DOUBLE ENDED: TYPES AD, CD & ED

These 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.

BACK-TO-BACK: TYPES ABB, CBB & EBB

These 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.

INTEGRAL REAR SWIVEL: TYPES AN, CN & EN

These 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

These 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.

THREE POSITION: TYPES: AP, CP & EP Single Ended TYPES: APD, CPD & EPD Double Ended

These 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 is 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-3x4x6. 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.

TANDEM: TYPE: ET SINGLE ENDED TYPE: ETD DOUBLE ENDED

The basic construction of these Cylinders is identical to Type “E” and features 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”.

Type “ETD”: 40”.
