Hydrauliska cylindrar - en central komponent inom industriella tillämpningar där stor kraft krävs
Hydraulcylindrar
Dessa cylindrar omvandlar hydraulisk energi till mekanisk energi och används för att utföra lyft, pressning, dragning och andra arbetsuppgifter inom olika sektorer.
Choose the right hydraulic cylinder
Hydraulic cylinders are a central component in many industrial applications where high power is required. These cylinders convert hydraulic energy into mechanical energy and are used to perform lifting, pressing, pulling and other tasks in various sectors. We have a variety of manual, electric or pneumatic hydraulic pumps with different functions and oil volumes that can be purchased and rented. Contact us and one of our experts will help you find the right pump for your equipment!

Types of hydraulic cylinders
Single-Acting Cylinders : Single-acting cylinders have pressure applied to one side of the piston, causing movement in one direction. The return is usually by a spring or gravity. These cylinders are often used where single motion is needed, such as in jacks.
Double-acting cylinders : Double-acting cylinders have pressure applied to both sides of the piston, allowing movement in both directions. This provides greater control and precision, making them suitable for applications where continuous motion is required, such as in industrial machinery and tools.
Telescopic cylinders: Telescopic cylinders, also known as multi-stage cylinders, consist of multiple inner cylinders that extend out like a telescopic antenna. These are used where long stroke is required but space is limited, such as in some mobile applications.
Maintenance and Safety: To ensure long life and performance, regular maintenance is essential. This includes checking oil levels, inspecting seals and hoses for leaks, and regularly lubricating moving parts. Safety is also a critical aspect, and it is important to follow the manufacturer's recommendations and safety precautions to avoid accidents and injuries.
What determines the right choice for your application?
The right torque wrench depends on several technical factors. The most important is the torque range required for the bolted joint – each tool has an optimal working range. The working environment plays a big role: hydraulics are best for heavy industrial assemblies, while pneumatic tools are suitable where the air is clean and the pressure is stable. For field service or difficult-to-access installations, battery-powered torque wrenches are the right choice. Material and bolt size also affect the need for reaction arms, fit, power sleeves and safety distances. Additional factors are access to electricity, air or a pump, as well as requirements for repeatability and documentation in production. Torctech helps you dimension tools and accessories according to your specific conditions.
Safety and calibration
To ensure correct tightening and avoid damage from overload, regular calibration is essential. Most torque wrenches should be calibrated at least once every 12 months , or more frequently in continuous production. Each tool has a torque curve that shows its tolerances at different loads, and this should be compared to the requirements specification for your applications. Tool wear , for example on the reaction arm, gears or drive square, can affect both precision and safety. Torctech offers complete service, calibration and function check where the performance of the tools is tested, adjusted and documented. This ensures that your torque wrenches deliver the right force every time.
Documentation and quality assurance
In modern industry , documented quality is often required for every torque tightening. Electric and some battery-powered torque wrenches offer features for logging torque values , number of cycles and any deviations. This is important for traceability, quality assurance and compliance with industry standards such as ISO 9001, ISO 6789 and ISO 5393. Repeatability and tolerances can be verified through calibration protocols and ongoing monitoring. Torctech offers systems that integrate tool documentation with your internal processes and ensure that you always have up-to-date protocols, whether you work in energy, offshore, manufacturing or heavy industry.
