Product catalog summary
Overview of SX Standard Programme
The document details the standard programme for hydraulic cylinders, compliant with ISO 6022 and DIN 24333 standards. Key specifications include a nominal pressure of 250 bar and a static proof pressure of 375 bar. Bore diameters range from 50 to 320 mm, and rod diameters from 32 to 220 mm. Six mounting styles are available, with optional cushioning. The fluid used is mineral oil, with a temperature range of -20 to 80°C and a viscosity range of 20 to 80.10-6 m2/s. Maximum piston speed is 0.5 m/s, and cleanliness must meet ISO 4406 standards.
Cylinder Selection Criteria
Selection factors include required force, working pressure, cylinder stroke, maximum piston speed, fluid medium, temperature range for seals, mounting style, cylinder bore, and rod diameter. Additional considerations are stop tube necessity, rod end thread, seal compatibility, cushioning, port size compatibility, and accessory requirements.
Mounting Types and Classes
Various mounting types are described, such as cap fixed eye and head circular flange. Vertical mounting is emphasized, ensuring bolts are not under tension at maximum force. Spherical bearings are recommended for cylinders pivoting in multiple planes. Mounting classes affect permissible stroke under thrust loads, with alignment crucial to avoid component flexing.
Specifications and Mounting Styles
Alignment in cylinder mounting is crucial to prevent sway and flexure. Pivoted centerline mounting is suggested for misalignment in one plane, and spherical bearings for multiple planes. Listed mounting styles include fixed mounts (MF3, MF4, MS2) and pivot mounts (MP3, MP5, MT4).
Rod Buckling and Load Calculations
Rod buckling is critical for cylinders in compression. The document provides a method using Euler's formula, considering modulus of elasticity and moment of inertia, with a recommended safety factor of 3.5. The procedure involves determining buckling length, calculating compression force, and using a graph for maximum buckling length.
Cushioning Capacity
Cushioning is recommended for piston velocities over 6 m/min or when moving large masses. It extends cylinder life and reduces shocks, though effectiveness decreases with higher drive pressures. A procedure to calculate energy absorbed by cushioning is provided, suggesting a larger bore cylinder if energy exceeds graph values.
Technical Data and Graphs
Detailed tables and graphs are included for calculating buckling length, energy absorption, and cushioning capacity. Specific data on piston and rod diameters, areas, and pressures for different cylinder sizes are provided. Graphs illustrate the relationship between drive pressure and energy absorption capacity.
Technical Specifications
1. Proximity Sensors: Used for piston rod control signals, these sensors are simple, accurate, and reliable, with specifications including a PNP output, 1.2 mm operating distance, 24VDC supply voltage, 200 mA load capacity, and IP-68 protection.
2. Position and Velocity Transducers: Provide control signals for position and velocity, with potentiometer and magnetostrictive types offering different resolutions and measuring ranges.
Procedures and Recommendations
1. Connection Types: Cable and connector types for proximity sensors are outlined.
2. Ordering Code for Cylinders: A detailed ordering code system is provided, specifying type, bore, rod, stroke, mounting style, ports, cushioning, seals, material, fluid, and special features.
Standards and Norms
Different types of hydraulic cylinders are specified according to ISO standards, including medium, compact, and heavy series.
Key Data from Tables and Figures
1. Cylinder Weights: Tables show weights for different bore and rod diameters, and additional weight per 10 mm stroke.
2. Transducer Specifications: Detailed specifications for potentiometer and magnetostrictive transducers are provided, including resolution, linearity, repeatability, and operating temperature ranges.

MOUNTING CLASSES El tipo de montaje de un cilindro afecta directamente a la carrera máxima admisible en cargas a compresión, pero además hay que tener en cuenta aspectos como tipo de amarre a la punta de vástago y posibles desalineamientos, que determinan también dicho montaje. Los tipos de montaje pueden clasificarse de la siguiente forma: A cylinder’s mounting affects directly to the maximum stroke at which the cylinder can be used for thrust loads, but there are factors like piston rod connection and misalignments that should also be considered. Mounting styles can be classified in this way:...

Cuando la longitud entre el apoyo del cilindro y la punta del vástago en cilindros que trabajan a compresión es importante, debe comprobarse a pandeo para evitar su deformación e incluso la rotura. When the length between cylinder mounting and application point of a piston rod that works in thrust (push) conditions is important, buckling length must be verified to avoid deformations and perhaps fractures. Cuando el grado de esbeltez sea mayor de 100, la resistencia al pandeo de los cilindros se calcula por la fórmula de Euler: If slenderness is greater than 100, buckling length is given by Euler...

CUSHIONING CAPACITY Con velocidades de pistón superiores a 6 m/min o bien grandes masas a mover, se recomienda disponer de amortiguación en los finales de carrera. Ello alarga la vida del cilindro y evita golpes indeseables. When the piston velocity is greater than 6 m/min or there are big masses to move, it’s recommended to use cushions at stroke ends. It extends cylinder life and reduces undesirable hydraulic shocks. La amortiguación se consigue básicamente estrangulando la salida final de aceite, con lo que se produce una contrapresión que actúa en sentido contrario al movimiento. Cushioning...
