Series KPZ

Aventics Serie KPZ compact cylinders are space-optimized pneumatic actuators designed for short-stroke applications where installation depth is critical. These double-acting cylinders serve automation systems in packaging machinery, automotive assembly lines, medical device manufacturing, and semiconductor equipment where precise positioning within confined spaces is essential. The KPZ series features bore sizes from 80mm to 100mm with stroke lengths ranging from 10mm to 100mm, making them ideal for clamping, lifting, and positioning operations in production environments where floor space commands premium costs.

Selection of Aventics KPZ compact cylinders requires matching bore diameter, stroke length, and mounting configuration to application requirements. Available bore sizes include 80mm and 100mm variants, with stroke options spanning 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 80mm, and 100mm as evidenced by models like KPZ-DA-100-0060 and KPZ-DA-080-0080. Operating pressure typically ranges from 2 bar to 10 bar, with force output calculated using bore area and working pressure. Port connections utilize standard G1/8 or M5 threading, while mounting options include front flange, rear flange, and trunnion configurations depending on load direction and installation constraints.

Aventics Serie KPZ cylinders comply with ISO 15552 dimensional standards for interchangeability with other manufacturers' compact cylinders and ISO 6431 mounting interfaces for standardized installation. The cylinders meet EN 61000 electromagnetic compatibility requirements for industrial environments and are manufactured according to ISO 9001 quality management standards. Depending on application requirements, specific models may carry CE marking for European machinery directive compliance and can be specified with food-grade sealing materials meeting FDA 21 CFR 177.2600 for direct food contact applications in packaging machinery.

Aventics KPZ cylinder variants differ primarily in bore diameter and stroke length combinations, with 80mm bore models like KPZ-DA-080-0100 providing different force characteristics than 100mm bore equivalents such as KPZ-DA-100-0100. Stroke lengths vary systematically from 10mm for micro-positioning applications to 100mm for extended reach requirements, while maintaining the same compact envelope design. All variants feature identical port threading and mounting interfaces but differ in maximum operating forces, with 100mm bore cylinders generating approximately 56% more force than 80mm variants at equivalent operating pressures due to increased effective piston area.

Aventics KPZ cylinders require filtered compressed air at 2-10 bar operating pressure with dewpoint at least 15°C below ambient temperature to prevent condensation in the cylinder bore. Standard port connections utilize G1/8 female threads compatible with push-in fittings or threaded adapters, while mounting follows ISO 15552 specifications for direct replacement compatibility with existing compact cylinder installations. The cylinders integrate with standard 5/2-way and 5/3-way pneumatic valves, requiring flow rates of 6mm diameter tubing minimum for stroke lengths exceeding 50mm to achieve specified cycle times under full load conditions.

Aventics Serie KPZ cylinders operate reliably within temperature ranges from -20°C to +80°C ambient conditions while maintaining seal integrity and consistent force output across the full pressure range of 2-10 bar. Standard models achieve IP40 protection rating against solid particle ingress, with optional IP65 variants available for washdown environments in food processing applications. The cylinders withstand maximum operating pressures up to 12 bar for short-duration applications and feature integrated safety factors of 4:1 against ultimate tensile strength of critical load-bearing components, ensuring reliable operation under dynamic loading conditions typical of automated manufacturing systems.

Aventics KPZ compact cylinders typically achieve 10 million operational cycles under normal industrial conditions with filtered air supply and proper lubrication, requiring seal replacement every 5 million cycles or 18 months of continuous operation. Preventive maintenance includes monthly inspection of port connections for air leakage using leak detection spray and quarterly verification that operating forces remain within specification using calibrated pressure gauges. Annual maintenance involves disassembly for seal inspection and replacement if shore hardness measurements indicate degradation below 70 durometer, while rod chrome plating should be examined for scoring or corrosion that could compromise seal life and cylinder performance.
