Review ASHUN Hydraulic Cylinder 63mm Bore 90mm Stroke 70kgf/cm Industrial

The **Ashun MOB63X90 hydraulic cylinder** is a robust, high-performance hydraulic actuator designed for demanding industrial applications where precision, durability, and reliability are paramount. Engineered with a **63mm bore diameter** and a **90mm rod diameter**, this cylinder delivers exceptional force output, making it ideal for heavy-duty machinery such as presses, forging equipment, material handling systems, and hydraulic presses. With a **working pressure rating of 70 kgf/cm (approximately 7 MPa or 1015 psi)**, it ensures consistent and powerful hydraulic operation while maintaining operational safety under high-load conditions. Constructed from high-grade materials, including a **chrome-plated steel rod** for enhanced corrosion resistance and extended service life, this cylinder is built to withstand frequent cycling, extreme temperatures, and harsh environmental conditions without compromising performance.

The MOB63X90 features a **double-acting design**, allowing for bidirectional force application, which is essential for applications requiring both extension and retraction movements with equal efficiency. Its **sealed double-acting structure** minimizes internal leakage, ensuring optimal hydraulic efficiency and reducing energy consumption over time. The cylinder incorporates **high-quality rubber or polyurethane seals**, such as NBR or Viton, which provide superior wear resistance and prevent contamination from entering the hydraulic system. Additionally, the **flanged mounting design** offers versatile installation options, accommodating various mounting plates and structural setups, while the **single or double rod end configurations** (depending on the model variant) allow for customization based on specific application requirements.

For enhanced durability, the Ashun MOB63X90 is equipped with **reinforced end caps and a robust tie-rod construction**, ensuring structural integrity even under high-pressure cycles. The cylinder s **smooth, low-friction piston rod** is precision-ground to minimize wear on seals and bearings, contributing to longer operational life and reduced maintenance needs. Whether integrated into a hydraulic press, a material testing machine, or an industrial automation system, this cylinder delivers **consistent, repeatable motion** with minimal hysteresis, making it a dependable choice for manufacturers seeking reliable hydraulic actuation. With Ashun s reputation for precision engineering and quality craftsmanship, the MOB63X90 represents a cost-effective yet high-performance solution for industries where hydraulic power is critical.

### **Pros and Cons of buying a Ashun MOB63X90 Hydraulic Cylinder (63mm Bore, 90mm Stroke, 70 kgf/cm Pressure)**

1. **Compact and Lightweight Design** The 63mm bore makes it suitable for applications where space is limited, such as in small hydraulic systems, industrial machinery, or mobile equipment. Its smaller size can reduce overall system weight, improving maneuverability.

- **Automotive lifting systems** (e.g., car lifts, jacks)

- **Industrial machinery** (e.g., presses, clamps, material handling)

- **Agricultural equipment** (e.g., hydraulic cylinders in tractors or harvesters)

- **Small-scale hydraulic presses or shears**

- **Hydraulic power units for workshops or maintenance tools**

3. **Cost-Effective for Small Applications** Compared to larger cylinders, this model is relatively affordable, making it a practical choice for budget-conscious buyers who don t require high-force or high-stroke applications.

4. **Compatibility with Common Hydraulic Systems** The 63mm bore is a standard size, meaning it can easily integrate with existing or commonly available hydraulic pumps, valves, and hoses (e.g., 1/2" or 3/4" hydraulic lines).

5. **Durability for Light to Medium Loads** Ashun is a reputable brand known for producing reliable hydraulic components. If properly maintained, this cylinder can provide years of service in controlled environments.

6. **Easy Installation and Maintenance** Smaller cylinders are generally easier to install and service compared to larger industrial models. The 90mm stroke is long enough for many applications without being overly cumbersome.

7. **Versatility in Mounting Options** Can be mounted in various orientations (piston rod up/down, side-mounted, etc.), depending on the application requirements.

---

- **Large-scale industrial presses** (e.g., metal stamping)

- **Heavy lifting in construction** (e.g., crane cylinders)

- **High-force hydraulic systems** (e.g., some automotive lifts or agricultural machinery)

The maximum force it can generate is roughly **300 kgf (3 kN)** at full pressure (Force Pressure Area). This may be insufficient for demanding tasks.

- **Long-stroke applications** (e.g., some hydraulic rams in material handling)

- **Systems requiring extended movement** (e.g., certain types of hydraulic actuators)

If the application requires a longer stroke, a different model would be needed.

3. **Pressure Limitations** 70 kgf/cm is relatively low compared to industrial-grade cylinders (which often exceed 100 200 kgf/cm ). This means:

- It may not handle sudden high-load spikes without risking damage.

- The system must be designed to operate within this pressure range to avoid leaks or failure.

4. **Potential for Leaks Over Time** Like all hydraulic cylinders, seals degrade with use. If not properly maintained, this cylinder could develop leaks, reducing efficiency and requiring repairs.

5. **Limited Customization** Ashun s standard models may not offer extensive customization options (e.g., rod coatings, special seal materials, or unique mounting flanges). Buyers with specific needs may need to source additional parts or modify the cylinder.

- **High temperatures** (unless specified otherwise)

- **Corrosive fluids** (e.g., untreated water, chemicals)

- **Abusive operating conditions** (e.g., frequent overloading, improper lubrication)

could shorten its lifespan.

7. **Dependence on System Compatibility** The cylinder must match the hydraulic pump s flow rate and pressure capabilities. Mismatches could lead to:

- **Slow operation** (if the pump is too weak)

- **Pressure spikes** (if the pump exceeds the cylinder s rating)

---

The **Ashun MOB63X90 hydraulic cylinder** is a **practical choice for light to medium-duty applications** where space is limited, and moderate force is required. It excels in scenarios such as automotive lifts, small industrial presses, agricultural equipment, or workshop tools. However, it is **not suitable for heavy-duty, high-force, or long-stroke applications**, where larger cylinders (e.g., 80mm bore, higher pressure ratings) would be necessary.

Its **pros** include compactness, affordability, and compatibility with standard hydraulic systems, while its **cons** revolve around limited force output, pressure rating, and suitability for only specific tasks. Proper maintenance and system compatibility are critical to ensuring longevity.

---

- You need a **small, lightweight hydraulic actuator** for light to medium loads.

- Your application requires **63mm bore and 90mm stroke** (e.g., car lifts, small presses, agricultural tools).

- You are working within a **pressure range of 70 kgf/cm ** and have a compatible hydraulic system.

- Budget and space constraints favor a smaller, cost-effective solution.

- You require **high force** (e.g., heavy lifting, metal forming, industrial presses).

- Your application needs a **longer stroke** (e.g., >100mm).

- You operate in **extreme conditions** (high heat, corrosive fluids, frequent overloads).

- You need **custom modifications** (e.g., special seals, coatings, or mounting).

- For **higher force**, look for cylinders with **larger bores (e.g., 80mm, 100mm) and higher pressure ratings (100 kgf/cm ).**

- For **longer strokes**, select models with **120mm, 150mm, or more.**

- For **heavy-duty use**, consider brands known for industrial cylinders (e.g., Bosch Rexroth, Parker, or Sunhydraulics).

If your application falls within the cylinder s specifications and you prioritize cost and compactness, the Ashun MOB63X90 is a **solid, reliable purchase**. Otherwise, upgrading to a larger or higher-rated cylinder would be advisable. Always verify compatibility with your hydraulic pump and system before purchasing.
