Pneumatics

Cylinder

Pneumatic cylinders convert compressed air into linear or rotary motion and are the most widely used actuator in industrial pneumatics. The range spans from standardised round cylinders to ISO 6432 with bore diameters from 8 mm, through ISO 15552 profile cylinders up to 320 mm bore, to compact cylinder series such as LCDQ, SQ and Unitop, plus special types including rodless cylinders, double-piston cylinders and guided cylinders. Mounting accessories, guide units, swivel tables, vacuum ejectors, vibrators and limit switches complete the range.

For corrosive environments, stainless-steel round cylinders to ISO 6431 and double-acting stainless-steel cylinders to ISO 6432 in grade 1.4301 are available. Oil-cushioned cylinders and industrial shock absorbers from ACE extend the programme where kinetic energy must be absorbed in a controlled manner.

What are Aventics cylinders and what industrial applications are they primarily used for?
Aventics cylinders are precision pneumatic actuators designed for industrial automation applications requiring controlled linear motion and force generation. These cylinders are extensively used in automotive assembly lines for part positioning and clamping, packaging machinery for product handling and sealing operations, and material handling systems for automated conveying and sorting. The ITS series tie-rod cylinders and CKP series slot cylinders serve manufacturing industries including food processing, pharmaceutical production, and semiconductor fabrication where reliable pneumatic actuation is essential. Aventics cylinders integrate seamlessly into factory automation systems requiring precise positioning accuracy and consistent cycle times.
What are the key technical selection criteria for choosing the right Aventics cylinder?
Selecting the appropriate Aventics cylinder requires evaluating bore diameter, stroke length, operating pressure range, and mounting configuration based on application force and positioning requirements. The ITS series offers bore diameters from 25mm to 320mm with stroke lengths ranging from 200mm to 500mm, while operating pressures typically range from 1.5 to 10 bar depending on cylinder series. Port connection sizes vary from G1/8 to G1/2 threads to match pneumatic supply line requirements, and mounting options include tie-rod, clevis, and flange configurations. Critical selection factors include required thrust force calculation, available installation space, cycle frequency, and environmental conditions such as temperature range and contamination exposure.
Which international standards and certifications apply to Aventics pneumatic cylinders?
Aventics cylinders comply with ISO 15552 international standard for pneumatic cylinders with detachable mountings, ensuring dimensional interchangeability and performance consistency across manufacturers. The tie-rod cylinder series ITS conforms to ISO 15552 specifications for mounting dimensions, port locations, and performance characteristics, enabling direct replacement compatibility with other ISO-compliant cylinders. Additional applicable standards include ISO 6432 for compact cylinders, ISO 21287 for profile cylinders, and ISO 15524 for stainless steel cylinders depending on specific product series. Manufacturing quality follows ISO 9001 standards, while ATEX certification is available for cylinders used in potentially explosive atmospheres, and food-grade versions meet FDA and EU regulations for direct food contact applications.
What are the main differences between Aventics ITS tie-rod cylinders and CKP slot cylinders?
Aventics ITS tie-rod cylinders feature external threaded rods connecting front and rear caps, providing maximum rigidity and force transmission capability for heavy-duty applications with operating pressures up to 10 bar. The ITS series offers bore diameters from 32mm to 320mm with stroke lengths up to 2000mm, making them ideal for high-force linear actuation in metalworking and assembly operations. CKP slot cylinders utilize an integrated slot design with external guided piston rod, providing anti-rotation capability and compact installation footprint for applications requiring precise positioning. The CKP series typically operates at pressures up to 8 bar with bore sizes from 12mm to 100mm, optimized for automated packaging and handling systems where space constraints and positioning accuracy are critical.
What installation requirements and system compatibility considerations apply to Aventics cylinders?
Aventics cylinder installation requires compressed air supply filtered to ISO 8573-1 Class 7.4.4 with operating pressure between 1.5 and 10 bar depending on cylinder series, plus adequate flow capacity to achieve specified cycle times. Port connections use standard metric threads from G1/8 to G1/2 or NPT threading, requiring proper thread sealant application and torque specifications to prevent air leakage. Mounting surfaces must provide sufficient rigidity to handle reaction forces, with tie-rod cylinders requiring additional clearance for rod extension access and maintenance. System compatibility includes integration with pneumatic control valves, pressure regulators, and position sensing systems, while electrical connections for proximity sensors require IP65-rated cable glands and proper grounding for industrial electromagnetic compatibility.
What safety ratings and operating conditions do Aventics cylinders support?
Aventics cylinders typically achieve IP54 to IP67 ingress protection ratings depending on series and sealing configuration, providing protection against dust ingress and water spray in industrial environments. Operating temperature range spans from -20°C to +80°C for standard sealing materials, with extended temperature options available using fluoroelastomer seals for applications up to +150°C. Maximum operating pressure varies by cylinder series, with ITS tie-rod cylinders rated for 10 bar continuous operation and CKP slot cylinders rated for 8 bar, both including 1.5x safety factor per ISO standards. Cylinders incorporate redundant sealing systems and mechanical position stops to prevent over-extension, while ATEX-certified versions provide intrinsic safety for Zone 1 and Zone 2 hazardous area installations in chemical and petrochemical facilities.
What maintenance schedule and service life expectations apply to Aventics pneumatic cylinders?
Aventics cylinders require periodic inspection every 6 months or 500,000 cycles under normal operating conditions, including visual examination of rod seals, mounting hardware, and pneumatic connections for wear or leakage. Seal replacement intervals typically range from 2 to 5 years depending on operating pressure, cycle frequency, and environmental contamination levels, with rod seals being the primary maintenance item requiring replacement. Expected service life exceeds 10 million cycles for standard applications operating within specified pressure and temperature limits, while harsh environments or frequent high-pressure operation may reduce service intervals. Maintenance procedures include lubrication of tie-rod threads, calibration of position sensors, and pressure testing of internal sealing systems, with complete cylinder rebuilds recommended every 5 to 7 years for continuous operation applications.
