AS/ASH Aluminum Pneumatic & Hydraulic Cylinders

Check up to five results to perform an action.


1. Piston Rods—5/8" thru 4" diameter are medium carbon steel with 100,000 psi minimum yield. Piston rods over 4” diameter have yield strengths between 50,000 and 90,000 psi. Sizes 4/8" thru 31/2" diameter are induction case hardened to 54 Rockwell C. All piston rods are hardchrome plated and highly polished.

2. Rod Wiper—Polyurethane, double lip type wiper designed to protect the piston rod, bearing and rod seal, is standard for all rod sizes. Also metallic scrapers and Viton wipers are available for all rod sizes.

3. Rod Gland Cartridge—The cartridges can be removed without removing mounts or bolts.This eliminates the necessity of cylinder disassembly to replace the rod seals or rod bearing. Rod Bearing—Aluminum bronze material insures low friction, high load capabilities and long life.

4. Rod Seal—Buna compound, flexible lip type rod seal has excellent break away. Inherent characteristics of the material and design assure leakproof performance and long life.

5. Ports—Large unrestricted ports permit maximum flow with minimum pressure drop.Heads may be rotated independently at 90° intervals for convenient port location.

6. Tube Seals—Positive sealing synthetic rubber “O” ring.

7. Tube—Aluminum precision extrusion, annodized bore for light weight, high strength, with excellent corrosion-resisting characteristics.Dovetail grooves along all four sides of the tube extrusion allow for quick installation of switches.

8. Assembly Bolts—High strength steel bolts treated for corrosion resistance.

9. Cushions—Self-aligning, synthetic rubber type seals provide a positive leak-proof cushion.This, together with adjustable cushion needle valve, offers an extremely accurate means of obtaining most efficient cushion characteristics for a variety of loads and speeds.

10. Heads and Caps—Aluminum accurately machined to assure perfect alignment of piston rod bearing, piston rod, piston, and tube. Heads and caps pilot on tube O.D. to prevent “breathing” and provide additional insurance against leakage.

11. Piston—High grade aluminum, 11/2" thru 4" bores. Pistons are one piece, pilot fitted to piston rod and locked.

12. Piston Seals—Flexible lip type piston seals provide positive sealing, low friction and long life.

13. Needle valves—Flush type needle valves are supplied. Large drilled passages provide maximum control of cushioning effect and assure rapid full power starts at beginning of stroke. Self contained, durable, high pressure design assures leak free operation.

Wrench Flats—Large wrench flats are chamfered to protect rod gland packing in installation. All standard piston rods through 51/2" diameter are furnished with two wrench flats. Additional flats are available upon request.

Pre-lubricated—A specially compounded tenacious lubricant permits operation on non-lubricated air. This assures long life under normal operating conditions.This ecological feature eliminates exhausting oil mist into the atmosphere.

JIC—These cylinders are designed to conform to JIC standards.

NFPA—The dimensioning and identification of the cylinders in this catalog are in accordance with the NFPA recommended imension code for fluid power cylinders.
