How to Read the SC63x100-S-CB Model Code

AirTAC SC pneumatic cylinders come in many different models. When you see model names such as:

1. SC63x100
2. SC80x200
3. SC50x50-S-CB

many people may not understand:

1. What is the bore size?
2. What is the stroke length?
3. Does it include a magnetic piston?
4. Does it have cushioning?

👉 That is why understanding the AirTAC SC cylinder model code is extremely important when:

1. Selecting cylinders
2. Ordering products
3. Replacing cylinders
4. Designing pneumatic systems

In this article, we will break down the following model in detail:

SC63x100-S-CB

👉 Each character has its own technical meaning.

What Does “SC” Mean?

SC is the name of AirTAC’s standard pneumatic cylinder series.

Features:

✅ Tie-rod cylinder

✅ Strong pushing force

✅ Easy replacement

✅ Affordable price

✅ Widely used in automation

👉 This is AirTAC’s best selling cylinder series.

Where Are SC Cylinders Commonly Used?

SC cylinders are widely used in:

1. Automation machines
2. Pneumatic presses
3. Pneumatic jigs
4. Conveyor systems
5. Packaging machines

👉 Because they:

1. Offer multiple bore sizes
2. Have easy accessory replacement
3. Are easy to source

What Does “63” Mean?

The number 63 means:

👉 Cylinder bore = 63mm

The bore determines:

1. Pushing force
2. Air consumption

F=P×AF = P \times AF=P×A

👉 Larger bore:

1. Produces greater force
2. But consumes more compressed air

How Much Force Does SC63 Produce?

At approximately:

1. 6 bar pressure

SC63 produces around:

1. ~180–190kgf

👉 This is why SC63 is very popular in:

1. Industrial machinery
2. Medium to heavy-duty automation systems

What Does “100” Mean?

The number 100 means:

👉 Stroke length = 100mm

This means:

1. The cylinder travel distance is:
2. 100mm

What Does Stroke Affect?

Stroke affects:

1. Travel distance
2. Stability
3. Vibration
4. Overall cylinder dimensions

👉 Excessively long stroke:

1. Causes vibration
2. Increases side load

What Does “S” Mean?

The letter “S” means:

👉 The cylinder includes a magnetic piston

The magnetic piston is used for:

1. Mounting magnetic sensors
2. Detecting piston position

Why Are Magnetic Sensors Important?

Sensors help:

✅ Detect cylinder position

✅ Control PLC systems

✅ Improve automation accuracy

👉 Most modern automation systems use magnetic sensors.

What Does “CB” Mean?

CB usually relates to:

1. Cushion
2. Mounting style
3. Optional configuration code

👉 Depending on the catalog version:

1. The meaning of CB may vary.

Therefore:

1. Always check the official AirTAC ordering code chart.

Why Is Cushion Important?

Cushion helps:

1. Reduce end-of-stroke impact
2. Reduce vibration
3. Increase cylinder lifespan

👉 Cushion is especially important for:

1. High-speed systems
2. Heavy loads
3. Long stroke applications

Common Mistakes When Reading Cylinder Codes

Looking Only at Bore Size

Example:

1. SC63x50
2. SC63x300

👉 Same bore size, but:

1. Completely different applications.

Forgetting to Check Magnetic Option

Without “S”:

1. Magnetic sensors cannot be installed.

👉 This is a very common mistake.

Selecting the Wrong Mounting Style

Incorrect mounting may cause:

1. Vibration
2. Side load
3. Faster piston rod wear

Conclusion

The model code SC63x100-S-CB tells you:

1. Cylinder series
2. Bore size
3. Stroke length
4. Magnetic piston option
5. Cushion/mounting configuration

👉 Understanding the ordering code helps you:

1. Select the correct model
2. Avoid ordering mistakes
3. Design pneumatic systems more accurately

👉 Most importantly:

1. Always verify the ordering code using the official AirTAC catalog.
