Product Description

The SCT tie-rod cylinder features bi-directional YCC sealing rings and a powerful double-stroke design, with a compact and refined appearance that ensures fast action and smooth, stable output. Each layer of the cylinder contains an individual piston, and during the push–pull process multiple pistons share the load, allowing the cylinder to achieve the most compact length while generating multiplied output force through its multi-layer stacked structure. This double-force design delivers stronger power, and the six-seal-ring configuration provides excellent sealing performance, enabling the cylinder to hold pressure up to 1.4 MPa without leakage.

SCT tie rod cylinder characteristic

·OLK standard cylinders.

·The piston seal adopts a special bi-directional sealing structure, featuring a compact design and oil-storage function.

·Tie-rod type cylinder; the front and rear covers are connected to the aluminum tube body with tie rods for high reliability.

·The piston rod can achieve multiple positioning points during its full stroke.

·Smooth and adjustable cushioning.

·Various cylinder specifications and mounting accessories are available for customers to choose from.

·High-temperature-resistant sealing materials are optional, allowing the cylinder to operate normally at 150°C.

Pneumatic Control Schemes for Multi-Position Cylinders

Each section of the cylinder contains a piston.

When the piston rod extends, all pistons generate pushing force. However, during retraction, only one piston produces pulling force.

The air inlet of Cylinder①is connected to Port A of the solenoid valve, and the air inlet of Cylinder④is connected in series to Port B of the solenoid valve. The air inlet of Cylinder③is connected to a silencer. When Port A of the solenoid valve is energized, the cylinders stay in the retracted position. When Port B is energized, the cylinders start to operate.

1.Extension

When the air supply is on:

Solenoid valve No.1 is energized, and the cylinder extends to the first stroke.

Solenoid valve No.2 is then energized, and the cylinder extends to the second stroke.

2.Retraction

When the piston rod is fully extended:

Solenoid valve No.1 and No.2 are both de-energized, and the cylinder fully retracts.

1. Extension (Forward Stroke)

When the air supply is turned on:

Solenoid valve No.1 and No.2 are energized at the same time.

The cylinder rod extends through all strokes until fully extended.

2. Retraction (Step-by-Step Return)
