Tri-State Hydraulics - Glassport Cylinder Works

INTRODUCING GLASSPORT CYLINDERS

Glassport cylinders are designed and built for heavy-duty mill-type applications in either air or hydraulic service. Only the highest quality materials and strictest machining tolerances are acceptable in every Glassport Cylinder. All phases of manufacturing, from component production to final assembly, are monitored for precise adherence to design specifications.

Glassport Cylinders are rapidly gaining a reputation among major OEM and direct-user customers are being both durable and dependable in applications with the toughest requirements. We are proud of our cylinders and our attention to detail; both are unsurpassed in the industry.

SPECIFICATION DATA

Mill-Type, Nonrotating Cylinders

Standard Glassport Cylinders can be selected in either Air or Hydraulic Service Designs.

SERIES GA2001: for Air Service, with operating pressures up to 200 psi. These cylinders are also available as:

SERIES GH1001: for Hydraulic Service, with operating pressures up to 1000 psi. Both series are offered in standard bore sizes 2 through 20 inches.

SERIES GH2002: for Hydraulic Service, with operating pressures up to 2000 psi. Available in standard bore sizes 2 through 16 inches.

SERIES GH3001: for Hydraulic Service, with operating
pressures up to 3000 psi. Available in standard bore sizes 3 through 16 inches.

Intermediate and fractional bore sizes are available upon request. Selection of a bore size depends on the force required and the pressure available.

Cylinder Mounting Styles (for each Series)

	Foot Mount (F)
	Trunnion Mount (T)
	Female Clevis Mount (C)
	Rod End (front) Flange Mount (R)
	Blind End (rear) Flange Mount (B)

Other mounting configurations are available upon request.

Cylinder Body

	Standard material is DOM Mechanical Steel Tubing. Hot Finished Seamless or Centrifugally Cast Steel is also used in the larger bore sizes.
	The bore of the cylinder is machined and honed to a 16 micro-inch finish.
	Chrome Plating is not standard but is an option.

Cylinder Heads and Flanges

	Cylinder Heads are constructed of steel.
	Flanges are steel welded to the Cylinder Body.
	Cylinder Heads and Flanges are assembled with through bolts. All bolts are Grade 8 quality high-strength steel.
	Standard design is Octagonal, with Round and other shapes available.

Piston Assemblies

	Standard material is high-grade extruded ductile iron.
	Steel and bronze overlayed steel are optional upon request
	Loaded Lip Seals are standard piston seals with cast iron Piston Rings, Chevrons and Wear Bands as options. Seal material is standard Urethane. Optional seal materials are available and should be specified for special fluid or temperature requirements. Glassport Cylinder should be consulted for recommendations.

Piston Rods

	Standard material is Carbon Steel 1045 with a minimum 100,000 psi yield strength. Induction hardening is optional, as is the use of alloy steels.
	Chrome Plating is standard on all Piston Rods.
	When Hollow Rods are required to reduce weight, DOM Tubing is used, with Chrome Plating on the OD.
	Wrench Flats are standard.

Rod Bearing and Gland Assembly

	Standard material is 660 Bronze for both the Bearing and Packing Gland.
	Chevron Rod Packing is standard, with Loaded Lip Seals available as an option.
	For special fluid or temperature requirements optional seal materials are available. Consult the manufacturer for recommendations.

Cushions

	Cushions are optional and will be supplied upon request.
	Cushion Assemblies are a multi-piece Bronze and Stainless Steel unit.

Stop Tubes

When Stop Tubes are recommended in long-stroke applications, their lengths must be specified along with the net stroke of the cylinder. Please consult.

Miscellaneous

	Metal Identity Tags are placed on all cylinders showing bore, stroke, model and serial number.
	Cylinder Drawings are provided with a Parts Bill of Materials included. Customer approval of drawings is recommended before manufacturing begins.
