Series KHZ

Aventics KHZ series pneumatic cylinders are compact short-stroke pneumatic actuators designed for applications requiring precise positioning in confined spaces. These cylinders serve automotive assembly lines, packaging machinery, and automated production equipment where rapid cycling and compact installation are critical. The KHZ series features double-acting configurations with bore sizes ranging from 63mm to 100mm, delivering reliable performance in machine building and industrial automation applications. Their compact design makes them particularly suitable for integration into space-constrained automation systems requiring consistent force output and positioning accuracy.

Technical selection of Aventics KHZ series cylinders requires evaluation of bore diameter, stroke length, and mounting configuration based on force requirements and installation constraints. Available bore sizes include 63mm, 80mm, and 100mm variants with stroke lengths ranging from 10mm to 100mm, as demonstrated by models like KHZ-DA-100-0100-M-NR and KHZ-DA-063-0080-M-NR. Operating pressure typically ranges from 2 to 10 bar with compressed air as the standard medium, while port connections accommodate standard pneumatic fittings. The designation system indicates bore size, stroke length, and mounting type, enabling precise specification for automation applications requiring specific force and travel characteristics.

Aventics KHZ pneumatic cylinders comply with ISO 15552 dimensional standards for pneumatic cylinders, ensuring interchangeability with standard automation components. The cylinders meet ISO 8573 compressed air quality requirements and conform to machinery directive 2006/42/EC for integration into automated systems. Manufacturing follows ISO 9001 quality management standards, while materials and sealing systems comply with relevant DIN standards for pneumatic applications. These certifications ensure compatibility with European industrial automation systems and facilitate integration into machinery requiring CE marking compliance for pneumatic actuator components.

The primary distinction between Aventics KHZ variants lies in the mounting configuration and actuation method, with KHZ-DA representing double-acting cylinders and KHZ-SA indicating single-acting configurations. Double-acting models like KHZ-DA-100-0100-M-NR provide pneumatic extension and retraction through dual air ports, while single-acting variants such as KHZ-SA-100-0025-O utilize spring return mechanisms for one direction of travel. The suffix designations indicate specific mounting types, with M-series featuring standard mounting options and specialized variants offering alternative installation methods. Selection depends on application requirements for bidirectional control versus spring-return operation in automated positioning systems.

Aventics KHZ cylinder installation requires standard G1/8 or M5 pneumatic connections compatible with compressed air systems operating at 2-10 bar pressure. Mounting configurations accommodate both front and rear mounting options through standard ISO bolt patterns, ensuring compatibility with existing automation frameworks. System integration requires consideration of air consumption rates, typically 0.1-0.5 liters per stroke depending on bore size and stroke length, while filtration should meet ISO 8573 class 7.4.4 for optimal seal life. Proper installation includes adequate support for cylinder mounting points and appropriate tubing sizing to achieve specified cycle times in automated applications.

Aventics KHZ cylinders operate within temperature ranges of -20°C to +80°C with working pressures from 2 to 10 bar, providing reliable performance across standard industrial environments. The cylinders typically feature IP54 protection ratings, offering adequate dust and moisture protection for most automation applications. Maximum operating frequency reaches 300 cycles per minute depending on stroke length and system pressure, while theoretical force output varies from 1960N at 6 bar for 63mm bore to 4710N for 100mm bore cylinders. These specifications ensure consistent operation in manufacturing environments requiring reliable pneumatic actuation within standard industrial temperature and pressure parameters.

Aventics KHZ pneumatic cylinders typically achieve 10 million cycles under normal operating conditions with proper air preparation and maintenance protocols. Routine inspection should occur every 500,000 cycles or annually, whichever comes first, focusing on seal integrity, mounting hardware, and air line connections. Preventive maintenance includes verification of air quality according to ISO 8573 standards, lubrication system function, and measurement of internal leakage rates not exceeding 10cm³/min at 6 bar. Seal replacement intervals depend on operating conditions but generally range from 5-8 million cycles, while proper filtration and regulated air pressure significantly extend component service life in automated systems.
