Cylinder

Aventics pneumatic cylinders are precision-engineered actuators that convert compressed air energy into linear mechanical motion for industrial automation applications. The ITS series tie-rod cylinders and CKP compact slot cylinders serve critical functions in assembly lines, packaging machinery, material handling systems, and manufacturing equipment across automotive, food processing, and pharmaceutical industries. These cylinders provide reliable linear actuation with operating pressures typically ranging from 1.5 to 10 bar, featuring standardized mounting configurations and port connections for seamless integration into existing pneumatic systems.

Aventics cylinder selection requires evaluating bore diameter, stroke length, mounting configuration, and cushioning options based on force requirements and application constraints. The ITS series offers bore sizes from 25mm to 320mm with stroke lengths ranging from 200mm to 1240mm, as demonstrated by models like the R480627509 with 320mm bore and 500mm stroke. Critical selection parameters include operating pressure rating up to 10 bar, piston rod diameter for buckling resistance, and cushioning type where models with designation codes ending in different suffixes indicate varying damping characteristics for smooth deceleration at stroke ends.

Aventics pneumatic cylinders comply with ISO 15552 international standard for tie-rod cylinders, ensuring interchangeability with other manufacturers and standardized mounting dimensions across the industry. The ITS series specifically meets ISO 15552 requirements for bore sizes, mounting configurations, and port specifications, while additional standards include ISO 6432 for compact cylinders and ISO 21287 for specific mounting variants. European conformity includes compliance with Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU for pneumatic systems, ensuring safe operation within specified pressure ranges and proper documentation for industrial machinery integration.

Aventics ITS tie-rod cylinders feature traditional four-tie-rod construction with ISO 15552 compliance for heavy-duty applications requiring higher force output and longer stroke lengths up to 1240mm, while CKP compact slot cylinders utilize space-saving designs with integrated guidance for precise positioning in confined spaces. The ITS series accommodates bore sizes from 32mm to 320mm with robust tie-rod assemblies for maximum rigidity, whereas CKP cylinders focus on compactness with bore sizes typically 25mm to 100mm and integrated linear bearings for enhanced lateral load capacity. Different model designations indicate single-acting versus double-acting operation, with ITS models offering various cushioning options and CKP units providing integrated mounting flexibility for direct installation.

Aventics cylinders require proper mounting surface preparation with flatness tolerance within 0.05mm per 100mm length and adequate support structures to prevent flexural stress during operation. System compatibility demands clean, dry compressed air supply with filtration to 5 microns and lubrication according to ISO 8573-1 Class 7:4:4 standard, while port connections utilize standard G1/8, G1/4, or G3/8 threads depending on cylinder bore size. Installation procedures must account for piston rod buckling calculations based on stroke length and side loads, requiring proper alignment within 0.1mm angular deviation and adequate clearance for full stroke extension plus safety margins for mechanical stops or emergency positioning.

Aventics pneumatic cylinders typically operate within temperature ranges from -20°C to +80°C for standard sealing materials, with extended temperature variants available for extreme conditions up to +150°C using specialized seal compounds. Operating pressure ranges from 1.5 bar minimum to 10 bar maximum working pressure, with proof pressure testing at 15 bar and burst pressure ratings exceeding 40 bar for safety compliance. Standard IP protection ratings reach IP65 for dust and water ingress protection, while specialized variants achieve IP67 rating for washdown applications in food processing environments, ensuring reliable operation under harsh industrial conditions with appropriate seal selection and surface treatments.

Aventics pneumatic cylinders require routine maintenance every 1 million cycles or 12 months under normal operating conditions, with seal replacement intervals extending to 5 million cycles depending on air quality and operating parameters. Service life typically ranges from 10 to 20 million cycles for standard applications, while high-cycle variants achieve over 50 million cycles with premium sealing systems and specialized coatings. Inspection procedures include checking piston rod straightness within 0.02mm per 100mm length, monitoring internal leakage rates below 5 cm³/min at 6 bar pressure, and verifying cushioning adjustment functionality, with complete overhaul recommended when internal leakage exceeds 20 cm³/min or visible seal damage occurs during visual inspection protocols.
