Short stroke cylinders and compact cylinders

Aventics short-stroke cylinders (KHZ series) and compact cylinders (KPZ series) are pneumatic actuators designed for space-constrained automation applications requiring precise linear motion over limited distances. These cylinders excel in packaging machinery, assembly lines, and material handling systems where mounting space is critical. The KHZ series delivers powerful actuation in minimal installation depth, while KPZ series combines high force output with compact overall dimensions. Industries including automotive manufacturing, food processing, and electronics assembly rely on these cylinders for pick-and-place operations, clamping mechanisms, and positioning tasks where conventional cylinders cannot fit.

Selection between Aventics KHZ short-stroke and KPZ compact cylinders depends on bore diameter requirements, stroke length, and installation constraints. The KPZ series offers bore diameters from 80mm to 100mm with stroke lengths ranging from 10mm to 100mm, as demonstrated by models like KPZ-DA-100-0010 through KPZ-DA-100-0100. KHZ cylinders provide similar bore sizing but optimize for extremely short stroke applications with specific mounting configurations. Operating pressure typically ranges from 2 to 10 bar, with G1/8 or G1/4 pneumatic connections standard. Force output varies proportionally with bore diameter, with 100mm bore cylinders delivering approximately 785N theoretical force at 10 bar supply pressure.

Aventics pneumatic cylinders comply with ISO 15552 for interchangeable mounting dimensions and ISO 19973 for pneumatic cylinder performance requirements. The cylinders meet EN ISO 13849 safety standards for pneumatic control systems and comply with ISO 8573 for compressed air quality specifications. ATEX directive 2014/34/EU certification ensures safe operation in potentially explosive atmospheres when specified. Construction follows ISO 6020 dimensional standards for tie-rod cylinders and ISO 6432 for compact cylinder interfaces. Manufacturing quality adheres to ISO 9001 standards, while environmental testing meets ISO 9227 corrosion resistance requirements for industrial service life expectations.

KHZ short-stroke cylinders feature optimized barrel length and specialized end cap design for applications requiring minimal axial installation space, typically offering strokes from 10mm to 100mm in ultra-compact housing. KPZ compact cylinders prioritize overall dimensional reduction while maintaining full stroke capability, incorporating integrated mounting options and standardized connection ports. The KHZ series utilizes space-saving tie-rod construction with reduced end cap projection, while KPZ cylinders employ welded barrel construction for enhanced rigidity. Both series accommodate double-acting operation with adjustable cushioning, but KPZ models include additional sensor groove options for position feedback integration that KHZ variants may not standard accommodate.

Aventics compact cylinders require compressed air supply meeting ISO 8573 class 7:4:4 quality standards with operating pressure between 2 and 10 bar for optimal performance. Installation demands proper alignment within ±0.5mm tolerance to prevent side loading and premature seal wear. Standard G1/8 or G1/4 pneumatic connections accommodate most industrial air supply systems, while M5 or M6 mounting threads provide secure mechanical attachment. Minimum bend radius for pneumatic tubing must exceed 5 times tube outer diameter to maintain flow characteristics. Temperature compensation requires consideration of thermal expansion across operating range from -20°C to +80°C standard, with seal materials selected accordingly for specific media compatibility requirements.

Aventics pneumatic cylinders achieve IP54 protection rating standard for dust and water spray resistance in industrial environments. Operating temperature range spans -20°C to +80°C for standard sealing materials, with extended temperature variants available for extreme conditions. Maximum operating pressure reaches 10 bar with safety factor of 4:1 according to ISO 19973 requirements. Corrosion resistance meets 240-hour salt spray testing per ISO 9227 standards through anodized aluminum construction and stainless steel components. Vibration resistance complies with IEC 60068-2-6 testing protocols, while electromagnetic compatibility follows IEC 61000 standards for industrial automation environments without interference concerns.

Aventics pneumatic cylinders typically achieve 10 million operating cycles under normal industrial conditions with proper compressed air quality maintenance per ISO 8573 standards. Preventive maintenance requires quarterly inspection of mounting alignment, connection tightness, and seal condition, with annual replacement of filter elements in air preparation units. Seal replacement intervals depend on operating pressure and duty cycle but generally occur every 2-3 years in continuous service applications. Visual inspection for rod scoring, barrel wear, and cushioning adjustment should occur monthly during scheduled equipment maintenance. Service life extends significantly when operating pressure remains below 8 bar and air quality meets specified cleanliness requirements, with proper lubrication extending seal life by approximately 40 percent over dry air operation.
