2026-03-05CS1G160-250: Tie-Rod Type Standard Cylinder, Reliable Choice for Large-Bore Heavy-Duty Drive
Product Positioning
The CS1G160-250 is a single-rod, double-acting, tie-rod type standard cylinder from SMC’s CS1 series, characterized by its square end caps, large-diameter tie rods, and exceptional durability. This series is specifically designed for heavy industrial applications requiring large thrust, long strokes, and high reliability, with bores ranging from 125mm to 300mm. This model features a 160mm bore and 250mm stroke, widely used in automotive manufacturing, steel/metallurgy, large packaging machinery, heavy assembly lines, and various automation scenarios demanding powerful linear drive force.
Core Highlights: Tie-Rod Rugged Structure, High Thrust Output
- Square End Caps & Large-Diameter Tie Rods for Rugged Durability: The classic structure with square end caps and four large-diameter tie rods provides excellent overall rigidity, capable of withstanding significant thrust and external impacts, making it ideal for heavy-duty, continuous operation applications.
- The cylinder tube material is either aluminum alloy (for strokes ≤1200mm) or iron (for strokes ≥1201mm), balancing lightweight construction with high pressure resistance.
- Large Bore for Powerful Thrust, Enables Heavy-Duty Drive: With a Φ160mm bore, the theoretical thrust at a standard 0.5MPa operating pressure is as high as 9400N (extension) / 10100N (retraction). At 0.7MPa, it reaches 13200N (extension) / 14100N (retraction).
- Thrust data covers the entire 0.2～1.0MPa range, with a maximum operating pressure of 0.97MPa, meeting various application needs from light to heavy load.
- Single Rod, Double-Acting Design for Flexible and Controllable Action: The single rod, double-acting design uses compressed air to power both the advance and return strokes, offering flexible and controllable action suitable for applications requiring thrust in both directions.
- Wide Operating Condition Adaptability, Easy Maintenance:
- Operating pressure range: 0.05～0.97 MPa, with a low minimum operating pressure of 0.05MPa for sensitive starting.
- Piston speed: 50～500 mm/s. Ambient temperature: 0～70°C.
- Lubrication type: Requires lubrication (lubrication-free option available), offering flexible maintenance choices.
- No Built-in Magnet, Clear Installation: This model comes without a built-in magnet (for position detection needs, the CDS1G160-250 series with a magnet is available), allowing flexible selection of magnetic switches based on actual requirements.
- Mounting style: Head flange type (indicated by “G” in the model). End cap material: rolled steel. Piston rod material: carbon steel. Piston material: cast iron, ensuring long-term reliability under heavy loads.

Structure and Features
According to SMC technical data, key features of the CS1 series include:
- Tie-Rod Rugged Structure: Four large-diameter tie rods run through the body, providing excellent impact and fatigue resistance for high-frequency, heavy-load industrial environments.
- Square End Cap Design: Optimizes mounting interfaces for easy combination with various accessories while enhancing overall aesthetics.
- Multiple Mounting Options: Besides the head flange type, other styles like rod flange, foot, and trunnion types are available, flexibly adapting to different equipment layouts.
- Standard Air Cushion: Adjustable air cushions on both ends effectively absorb impact energy at the end of the piston stroke, ensuring smooth stops and protecting the cylinder and load equipment.
- Wide Bore and Stroke Range: Bores from 125mm to 300mm, with strokes customizable up to several thousand millimeters, covering most heavy-duty applications.
Applicable Scenarios
- Automotive Manufacturing: Control of large clamping fixtures in welding stations, heavy component handling, positioning on assembly lines.
- Steel & Metallurgy: Auxiliary rolling mill equipment, furnace door opening/closing, heavy stop devices.
- Large Packaging Machinery: Heavy material pushing, pallet positioning, pressing large cardboard boxes.
- Presses & Testing Equipment: Press-fitting, stretching, and testing stations requiring very high thrust and long strokes.
- Heavy Assembly Lines: Assembly and transfer of large components like engines and transmissions.
- Hydraulic System Replacement: A clean alternative in applications needing high thrust but wishing to avoid hydraulic oil contamination.
Summary: The Powerful Drive Core for Heavy Industrial Automation
The CS1G160-250 tie-rod type standard cylinder, with its three core technical advantages—tie-rod rugged structure, near 10-ton thrust from its Φ160mm large bore, and wide 0.05～0.97MPa pressure adaptability—perfectly addresses the core challenge in heavy automation equipment: “requiring extremely high thrust with long-term operational reliability.” Its square end caps and four large-diameter tie rods ensure exceptional durability in harsh conditions. The head flange mounting provides a stable foundation for equipment integration, and the absence of a built-in magnet offers selection flexibility. Choosing the CS1G160-250 means equipping your heavy automation line with a powerful, reliable, and durable “industrial power heart”—the ultimate choice for tackling heavy loads, high frequencies, and long-lifecycle demands.
