Drives
Structural Classification and Operational Characteristics
The product range includes highly engineered solutions tailored to diverse kinematic requirements of industrial installations:
- Hydraulic Cylinders (Linear Actuators) – converting fluid energy into reciprocating linear motion. The portfolio encompasses piston-type cylinders (both single- and double-acting) as well as plunger cylinders. They feature a wide selection of bore and rod diameters, alongside variable stroke lengths, enabling the generation of forces reaching multiple tons.
- Hydraulic Motors (Rotary Drives) – transforming fluid pressure energy into the rotary motion of an output shaft. Depending on the required rotational speed and torque output, various designs are utilized (such as piston or orbital motors), which excel in driving mobile machinery, winches, conveyors, or mixers.
Mounting Options and Custom Configurations
To ensure mounting versatility within various mechanical structures of machinery, linear actuators are manufactured with different types of rod ends and bearing support configurations:
- Spherical and Swivel Mountings – rod ends and cylinder bases equipped with spherical bearings, ideal for compensating angular misalignments.
- Rigid Mountings – front or rear mounting flanges, feet, and lugs, ensuring a stable, fixed positioning within the machine frame.
- Trunnion Mountings – transverse pivot pins (trunnions) integrated directly with the cylinder tube.
Advanced Features and Specialized Executions
To meet the demands of modern industrial automation and harsh environmental conditions, the drives can be equipped with advanced auxiliary functionalities:
- Position Measurement Systems – cylinders fitted with integrated internal linear transducers (position sensors), allowing for precise interaction with proportional valves in closed-loop feedback systems.
- End-Position Cushioning – damping systems that eliminate piston impact against the cylinder head or cap, extending the mechanical lifetime of the entire kinematic joint.
- Executions for Aggressive Environments – drives featuring specialized protective rod coatings (e.g., multi-layer chrome, nickel-chrome plating) and dedicated sealing packages, engineered to operate under high working pressures ($p_{max}$), extreme temperatures, or in contact with fire-resistant fluids.
