Cylinders

Allenair Cylinders

Type A Single Ended

Allenair Cylinder - TYPE A SINGLE ENDED
All Type “A” Cylinders, 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”
Type C Single Ended

Allenair Cylinder - 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”(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 & 4”
Type E Single Ended

Allenair Cylinder - 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 side load conditions prevents metal-to-metal contact. These Cylinders are generally used on low pressure hydraulics and where side load conditions are present.

Back-To-Back: Types ABB, CBB & EBB

Allenair Cylinder - Back to Back
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 fi xed 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.

Allenair Cylinder - Non Rotating
Internal guide rods.

  • Bore Sizes Available: 2”, 3”and 4”
Integral Square Head:
Types AS, CS & ESPES
Types ASD, CSD & ESD

Allenair Cylinder - Integral Square Head
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

Allenair Cylinder - 3 Position
These Cylinders feature two separate piston rod assemblies which provide three defi nite and positive positions. Any combination of fi rst stroke and total stroke is available. Both rods fully retracted is fi rst position. Port #1 Extends rod fi rst stroke to second position. Port #2 Extends rod full stroke to third position. Port #3 Retracts both rods to fi rst position. When ordering, second stroke must be specifi ed as total stroke, as second Cylinder rod moves through both strokes. For example, if fi rst 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

Allenair Cylinder - Tandem
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 fi lling the front Cylinder with oil and piping its ports in series using a fl ow control valve. The output force of a single Cylinder can be almost doubled using a Tandem Cylin- der 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”

Valves

Allenair Valves

These Allenair Valves are rugged, fi eld proven Slider-type 4-Way 2-Position Valves that can be mounted in any plane. They are available in a wide range of Solenoid, Pressure Pilot, Bleed Pilot and Manual Models. The basic principle of operation is the use of a pilot operated spool which moves the slider across the internal porting. Operating pressure 10 P.S.I, to 150 P.S.I, maximum.

  • Large coil cover eliminates need for separate splice box & can be rotated 360°
  • High tensile aluminum spool caps hardcoated for corrosion resistant valve seat.
  • Stainless steel plunger spring provides positive return & permits valve to be mounted in any position.
  • Lightweight Delrin spool for fast response.
  • Class B(130°C) Molded coil fungus & moisture-proof.
  • Stainless steel plunger with viton seats, compensating upper seat for extra long life.
  • Stainless steel precision welded plunger housing requires no special tool for removal.
  • High tensile manganese bronze slider lapped fl at within one light band. Spring loading permits valve to be mounted in any position.
  • Large ported aluminum valve base hardcoated with slider seal surface lapped flat within one light band and solid film lubricated for positive seal, low friction and anti-wear characteristics.
  • Two independent built-in adjustable speed Controls.

Rotary Index Tables

Allenair Rotary Index Tables

Allenair Rotary Index Tables are precision indexing mechanisms . . . unsurpassed in accuracy, performance and dollar value. Every detail of construction is designed to increase durability and effi ciency, and provide for long, trouble-free life. All parts susceptible to wear are carefully hardened. Bronze and roller bearings are incorporated. Working parts completely enclosed to protect against dust, dirt, and chips.

The Tables effect substantial savings in time and money in a wide variety of applications. For example, the Tables permit fast, automatic feeding of parts to tools in machine and assembly operations. Parts can be loaded and unloaded while machining operations continue. Other applications include cleaning and positioning operations, as well as use in conjunction with conveyor drive units.

Allenair Rotary Index Tables are available in a COMPLETE PRODUCT RANGE of four basic models, and each model can be supplied with any one of the following operating options.

  • As a basic Table with no operating valves. A 2-way or 3-way valve can be mounted on the rear of the drive cylinder as an option.
  • As a basic Table with a Pilot Timer Valve (PTV4), a 2-way valve (V2), and piped with flexible air hose ready for continuous automatic indexing.
  • As a basic Table with a Single Solenoid Bleed Pilot 4-way Valve (VSESA-AAS-1/4), a 2-way valve (V2), and piped with flexible air hose ready for use.
  • As a basic Table with a Single Solenoid Pressure Pilot 4-way Valve (VSSAP-AAS-1/4), a 3-way valve (V23), and piped with flexible air hose ready for use.
  • As a basic Table with a Double Pressure Pilot 4-way Valve (VAP-1/4), a 3-way valve (V23), and piped with flexible air hose ready for use.
  • As a basic Table with a Double Bleed Pilot 4-way Valve (VSA-1/4), a 2-way valve (V2), and piped with a flexible air hose ready for use.
