How Much Weight Can an SC63 Pneumatic Cylinder Push?

What is an SC63 Cylinder?

The SC63 is a pneumatic cylinder with:

1. A 63mm bore diameter
2. A standard tie-rod cylinder design commonly used in industrial automation

This cylinder size is widely used in:

1. Packaging machines
2. Conveyor systems
3. Automation equipment
4. Clamping and pressing applications

👉 The SC63 is popular because it offers a good balance between:

1. Output force
2. Cylinder size
3. Cost efficiency

How Much Force Can an SC63 Cylinder Produce?

The pushing force of an SC63 pneumatic cylinder depends on:

1. Air pressure
2. Cylinder type
3. Real-world operating conditions

According to the thrust table in the AirTAC SC catalog, at a common operating pressure of 0.5 MPa (5 bar), the SC63 cylinder produces approximately:

1. Around 150–160 kgf during extension
2. Around 130–140 kgf during retraction

👉 However:

1. These are theoretical values
2. In real applications, a 20–30% safety margin is recommended

How to Calculate SC63 Cylinder Force

Cylinder force can be calculated using the formula:

F=P×AF = P \times AF=P×A

Where:

1. F = force (N)
2. P = air pressure
3. A = piston area

With a 63mm bore:

1. The piston area is significantly larger than SC40 or SC50 cylinders
2. Therefore, the pushing force is much stronger

Why Can’t the SC63 Push the Full Theoretical Load?

Many people assume:

“If the SC63 can generate 150kg force, it can push a 150kg load.”

👉 In reality, this is not entirely correct.

Actual performance is affected by:

1. Friction
2. Mounting angle
3. Off-center loads
4. Air quality
5. Operating speed

👉 In practice:

1. Only about 60–80% of the theoretical force should be used

When Should You Use an SC63 Cylinder?

The SC63 is suitable for:

1. Medium to heavy loads
2. Applications requiring relatively high force
3. General industrial automation

Typical applications include:

1. Carton pushing
2. Product clamping
3. Mechanical movement systems
4. Light pressing machines

👉 In medium-load industrial applications, AirTAC SC63 cylinders are among the most commonly used models.

👉 If the required load is not extremely heavy:

1. The SC63 is usually the more cost-effective choice

Common Problems When Using SC63 Cylinders

Choosing Stroke Length That Is Too Long

1. Increased vibration
2. Higher risk of rod bending

Insufficient Air Pressure

1. Weak pushing force
2. Unable to move the load

Incorrect Mounting Type

1. Off-center loading
2. Faster seal wear

👉 These are among the most common issues in pneumatic systems.

How to Choose the Right SC63 Cylinder

When selecting an SC63 cylinder, consider:

1. Stroke length
2. Mounting type
3. Air pressure
4. Actual load
5. Installation space

👉 For heavy loads or long strokes:

1. Consider using:
2. guided cylinders
3. or external linear rails

Conclusion

The SC63 is one of the most popular pneumatic cylinder sizes because it provides:

1. Strong pushing force
2. Reasonable dimensions
3. Good cost efficiency

At a common pressure of 5 bar:

1. The SC63 can theoretically generate around 150kgf of force

👉 However, in real-world system design, you should always consider:

1. Load safety margins
2. Friction
3. Proper stroke selection
4. Correct mounting methods
