Pneumatic Cylinders and Actuators

Pneumatic Actuators

For engineers who know that motion control defines machine performance, Fokca delivers pneumatic actuators built on a simple promise: consistent, reliable movement, every cycle.

Pneumatic Cylinders – The Foundation of Motion

The cylinder is where compressed air becomes work. Our range covers the standards you expect, with the options you need:

• ISO 15552 cylinders: The workhorse of automation. Bore sizes 32-125mm, multiple mounting styles, interchangeable with global brands. For packaging machines, assembly stations, material handling.

• ISO 6432 compact cylinders: When space is tight. Bore sizes 8-25mm, lightweight, economical. For small devices, clamping, light pushing.

• ISO 21287 compact cylinders: Even shorter, even stronger. Reduced overall length without sacrificing force. For tight installations, machine building.

• Guided cylinders: When rotation isn't an option. Integrated guide rods, non-rotational precision. For precise positioning, guided loads.

• Double rod cylinders: Balanced forces, equal displacement both ends. For guided applications, parallel movements.

• Rodless cylinders: For long strokes where space is limited. Magnetic coupled or mechanical slotted versions.

• Stainless steel cylinders: For washdown environments. 304/316 construction, food-grade options. For food processing, pharmaceutical, corrosive conditions.

The Parts That Complete the System

Cylinders don't work alone. Every installation needs the right attachments: 

Beyond Cylinders – Grippers and Rotary Actuators

When the job requires more than linear motion:

• Parallel grippers: Synchronized jaws, high grip force. For pick-and-place, assembly.

• Angular grippers: Wide opening angle, compact. For confined spaces, simple gripping.

• 3-point grippers: Self-centering. For round parts, centered gripping.

• Rack and pinion rotary actuators: Precise angular positioning. 90°, 180°, 360° options.

• Vane rotary actuators: Smooth rotation, compact. For limited spaces, light duty.

What Actually Wears Out?

Pneumatic actuators fail. Seals wear. Rods score. Misalignment kills. Our designs address the real-world causes:

• Hard chrome plated piston rods: Resists scoring, extends seal life

• Multiple seal options: NBR for general, FKM for high heat, EPDM for special fluids

• Adjustable cushions: Smooth deceleration, less shock at stroke end

• Magnetic piston option: Reliable position sensing

When Standard Isn't Enough?

We do custom. No minimum quantity games.

• Special stroke lengths

• Modified mounting configurations

• High-temperature seals (FKM to 150°C)

• Food-grade lubricants, FDA materials

• Non-standard port locations

Quick Numbers – What to Consider

• Required force (kg) = pressure (bar) × piston area (cm²) × 1.02

• Operating pressure: 1-10 bar standard

• Temperature: -20°C to +80°C standard (wider options available)

• Cushioning: adjustable, non-adjustable, or air cushion

• Sensing: magnetic piston for position switches

Common Questions

Q1: ISO 15552 vs ISO 6432 – what's the difference?

The 15552 series is for general automation, larger bores (32-125mm). The 6432 series is compact, smaller bores (8-25mm), light duty.

Q2: Guided or standard – which do I need?

Guided cylinders when the load can't rotate or when you need precise linear motion without external guides. Standard when the load is guided elsewhere.

Q3: Custom strokes – really?

Yes. Tell us what you need.

Q4: Seal materials – what's available?

Standard NBR (-20°C to +80°C). FKM for high heat (up to 150°C). EPDM for special applications. Just ask.
