Pneumatic Cylinders in Pakistan – Trustworthy Linear Actuators for Industrial Automation

Pneumatic cylinders are the most commonly used automation devices in today’s industries. They are powered by compressed air to move in a linear direction, making them effective in performing tasks involving pushing, pulling, holding, lifting or moving.

Pneumatic cylinders have been widely applied in various industries in Pakistan ranging from textile industries of Faisalabad to pharmaceutical companies of Karachi and food processing units. They make sure efficiency and effectiveness of operation. Pneumatic cylinders from SS Hussain are available in all standard sizes and have excellent technical guidance on their selection and fitting.

Pneumatic Cylinder Working Mechanism

A pneumatic cylinder is made up of a cylinder barrel, piston, piston rod, seals, and end caps. The cylinder barrel gets pressurized, driving the piston to produce linear motion with air pressure.Industrial processes make use of double acting pneumatic cylinders in which air drives piston in both directions. There is another version of pneumatic cylinders known as single acting cylinders, where air works only in one direction.

Different Pneumatic Cylinder Types

• ISO 15552 Standard Cylinders

The most popular cylinder type used in industrial automation systems. Various bore and stroke sizes can be offered, as well as adjustable cushions and magnets to indicate the position of the piston.

• ISO 6432 Mini Cylinders
  
  Small pneumatic cylinders with a cylindrical body design suitable for use in small machinery, laboratory apparatus, packaging machines and instrumentation systems.
  
  
• Rodless Cylinders

Long stroke cylinders with reduced dimensions.Mainly used in conveyor systems and material handling devices.

Common Applications for Pneumatic Cylinders

Pneumatic cylinders have multiple uses, including:

• The textile industry
• Pharmaceutical manufacturing
• Food manufacturing
• Automotive manufacturing
• Packaging Systems
• Water Treatment Facilities
• Chemical Processing Plants.

How to Select a Pneumatic Cylinder

When you choose a cylinder, consider the following:

• The bore diameter and the amount of force required for your application;
• The length of stroke;
• The amount of air pressure that will be applied;
• The mounting configuration;
• The type of seal;
• Whether or not cushioning is needed at the end of the stroke; and,
• Whether or not position detection is needed.

A properly sized cylinder will help improve efficiency; reduce wear; and increase the lifespan of the cylinder.

Maintenance Guidelines for Pneumatic Cylinders

To keep pneumatic cylinders functioning efficiently, do the following:

• Frequently check for air leaks at the rod seal;
• Inspect rod for scratches and/or corrosion;
• Use a high-quality Filter/Regulator/Lubricator System (FRL) to provide good particle filtration and maintain a clean, dry supply of air;
• Regularly check that all mounting bolts are properly tightened;

If you hear a noise after hitting the end of the stroke, adjust the cushion to avoid damage; and by installing correctly and controlling the quality of your air supply, you can achieve trouble-free operation from your pneumatic cylinders for many years.

 FAQs

What is the application of pneumatic cylinders?

Pneumatic cylinders are used to convert compressed air into linear motion and are employed in lifting, pressing, clamping, positioning, and conveying applications.

Which pneumatic cylinder is suitable for industrial automation in Pakistan?
