Telescopic slides for every load requirement
Choosing the right telescopic slide starts with understanding the load requirements of your application. Depending on the weight, frequency of use, and operating environment, telescopic slides are generally divided into three categories: low duty, mid duty, and heayy duty solutions.
Each category is designed to deliver the right balance between load capacity, extension, durability, and smooth operation.
Low duty telescopic slides
Low duty telescopic slides are ideal for lightweight applications where compact design and smooth movement are essential. These slides are commonly used in furniture, interior fittings, retail displays, and light industrial equipment.
They offer reliable performance for applications with moderate loads and frequent movement, while maintaining a slim profile and efficient use of installation space.
Typical characteristics:
- Lightweight load capacities
- Compact and space-saving designs
- Smooth and quiet operation
- Suitable for frequent daily use
Proven telescopic slides for low duty applications
Mid duty telescopic slides
Mid duty telescopic slides provide increased strength and stability for applications that require higher load capacities and greater durability. They are widely used in industrial equipment, storage systems, medical devices, and vehicle interiors.
These slides combine smooth linear motion with enhanced structural performance, making them suitable for both commercial and industrial environments.
Typical characteristics:
- Medium load capacities
- Enhanced stability and durability
- Available in multiple extension types
- Suitable for intensive daily operation
Proven telescopic slides for mid duty applications
Heavy duty telescopic slides
Heavy duty telescopic slides are engineered for demanding applications involving high loads, harsh environments, and intensive use. These slides are commonly used in industrial machinery, defense applications, emergency vehicles, transportation equipment, and large storage systems.
Designed for maximum strength and reliability, heavy duty slides maintain smooth operation even under extreme conditions and high dynamic loads.
Typical characteristics:
- High load capacities
- Robust construction for demanding environments
- Long extension possibilities
- Reliable performance under intensive use

Technical information about telescopic slides
The performance and durability of telescopic slides depend on several technical factors, including load capacity, extension type, materials, surface treatment, and environmental conditions. Understanding these characteristics helps ensure the right slide selection for your application.
Load capacity
The load capacity of a telescopic slide is influenced by multiple factors, including slide length, extension ratio, mounting position, and frequency of use. Additional features and environmental conditions can also affect overall performance.
Telescopic slides are typically designed for either dynamic or static applications:
- Dynamic load capacity: refers to applications with continuous movement and repeated opening and closing cycles.
- Static load capacity: applies to situations where slides mainly support weight while remaining in a fixed position.
Selecting the correct load capacity is essential to guarantee smooth operation, long service life, and reliable performance in demanding environments.
Please note that the load capacities referenced on our website are based on dynamic load capacity values.
Extension types
Telescopic slides are available in different extension configurations to suit various application requirements. The extension defines how far the slide can travel compared to its closed length.
Common extension types include:
- Partial extension
- Full extension
- Over extension
The right extension type depends on accessibility requirements, available installation space, and load conditions.
Load capacity of telescopic slides at different extension ratios
The graph below illustrates the relationship between slide length and maximum load capacity for telescopic slides. Different extension ratios (T = 80%, 100%, and 125%) are compared to show how extension length influences performance. The results indicate that load capacity varies depending on both the slide length and the degree of extension, with higher extension ratios generally resulting in lower load capacities.
