The risk of leakage refers to the danger that a system will uncontrollably release operating fluids—such as hydraulic oil, lubricant, or other liquids—to the outside, for example due to worn seals, leaky screw connections, damaged lines, or material fatigue. This concept plays a central role, particularly when comparing hydraulic and electromechanical drive systems.
Causes and Consequences
- Seal wear, pressure surges, and temperature fluctuations are typical causes of problems in hydraulic cylinders
- Environmental impact from oil leaks, as well as potential fire and slip hazards
- Additional costs for spill containment pans, cleaning, and maintenance
- In hygiene-sensitive areas, there is also a risk of contamination for products or processes
Practical Applications in Thread Technology
Electromechanical screw drives, such as ball screws and trapezoidal screws, operate without hydraulic oil and therefore pose virtually no risk of leakage. This makes them a low-maintenance and clean alternative to hydraulic cylinders, particularly in applications with high standards for cleanliness and process reliability, such as in the food, pharmaceutical, and packaging industries, or in cleanroom environments.
