Product Overview: This single-acting hydraulic displacement cylinder is designed for high performance and durability, suitable for demanding industrial applications. With a maximum working pressure of 200 bar and a testing pressure of up to 300 bar, it ensures reliable operation under extreme conditions.

Key Characteristics:

• Maximum Working Pressure: 200 bar
• Maximum Testing Pressure: 300 bar
• Maximum Working Speed: 0.5 m/s
• Working Temperature Range: -30 ºC to +90 ºC
• Compatible Oil: Mineral hydraulic oil

Material Specifications:

• Rod: Constructed from chrome-plated steel F-1140, featuring a minimum chrome layer thickness of 20 microns, surface roughness Ra < 0.2, and a minimum surface hardness of 900 HV. The rod offers excellent corrosion resistance, with a minimum of 200 hours in neutral saline fog according to ISO9227, rated at 9.
• Tube: Made from steel ST-52-3 (DIN 2393), with an inside diameter tolerance conforming to ISO H9 and a roughness of Ra < 0.8 microns.
• Guide-Bushing: Steel F-1140, nitrited for enhanced durability and resistance to wear.
• Piston: Steel F-1140, engineered for optimal performance.

Sealing Components:

• Guide-Bushing:
  • Dynamic: Features a compact polyurethane rod-seal with a double lip, complemented by an NBR metal wiper seal for superior sealing performance.
  • Static: Sealed with an NBR 90 shore O-ring.
• Piston:
  • Dynamic: Equipped with a compact double-acting polyurethane seal and a nitrile O-ring as an activator, along with special polyacetal guides reinforced with glass fiber for enhanced stability.
  • Static: Secured with a polyamide locking sealing guide.

Finishing:

• Coating: The cylinder is finished with a black prime painting, offering additional protection against environmental elements.

Recommendations for Use:

• Protect the cylinder circuit with a relief valve set at 200 bar to prevent overpressure damage.
• Ensure the cleanliness of the hydraulic oil by using appropriate filters to prevent contamination.
• Before starting up, bleed the circuit by slightly loosening the cylinder fittings to remove any trapped air.
• Avoid welding directly on the cylinder tube to prevent damage. If welding on the rod or bottom is necessary, dismount the cylinder first.
• For long-term storage, avoid outdoor exposure. If outdoor storage is unavoidable, fully retract the rod or apply grease for protection.
• During high-pressure cleaning or blasting, protect the rod and oil ports to prevent damage.
• For double-acting cylinders used as single-acting, connect the unused oil port to the tank.
• If disassembly is required, note that the piston is screwed onto the rod end and secured with industrial glue. Use industrial glue when reassembling the cylinder.

This hydraulic cylinder is meticulously engineered to meet the highest standards of performance and durability, making it an ideal choice for heavy-duty applications.
