Mechanical components
Mechanical components include moving and load-bearing parts that are part of industrial machines, structures and mechanical systems. They are characterized by their ability to transmit force, motion or load, and are used in everything from precise control systems to robust lifting and locking solutions.
- Spherical rod ends and spherical plain bearings
For applications with rotating or tilting movements under load. Often used in hydraulic cylinders, steering systems and moving joints in industrial machinery. - Telescopic rails and linear guides (Slide and Fit° and °Slam lock handles)
Precision components for controlled linear motion and robust handling. Telescopic rails and guides provide stable sliding action, while Slide and Fit and Slam lock handles provide effective locking and ergonomic use in industrial enclosures and structures. - Safety fixing nuts
Specially designed nuts that prevent bolts from loosening due to vibration or mechanical impact. Used in applications with high safety requirements and moving machinery. - Industrial fastening systems
Modular and specialized solutions for fixed mounting of components and structures. Used in production lines, constructions and automation systems. - Gas springs
Components that provide controlled opening and closing of lids and doors. Used in everything from industrial cabinets to heavy lids in transportation and mechanical engineering. - Lifting eyes and locking bolts
Safety-critical components for lifting and mechanical locking. Used in maintenance, construction and heavy assembly.
- Universal joint
Joint for transmitting torque between angularly offset shafts. Used in rotating systems where flexibility is required. - Flexball and Duraflex remote controls
Precise and flexible remote controls for mechanical transmission of power or motion. Used in vehicles, marine installations and technical systems. - End joint technology
Components for efficient motion transmission in mechanical systems. Ensures stability and function in dynamic installations. - Machine and standard parts
Standardized components such as screws, bolts, nuts and spacers – used in the assembly and maintenance of industrial machinery. - Clamping tools
Tools and components used to clamp or securely fasten parts during manufacturing or assembly. - Industrial components
A wide range of mechanical parts and assemblies developed for reliable operation in industrial environments. Designed for long life and high performance.

Industrial components
A wide range of mechanical parts and assemblies developed for reliable operation in industrial environments. Designed for long life and high performance.
Pneumatic and hydraulic components
These components use air or fluid pressure to create motion, force or control in industrial applications. Pneumatics and hydraulics provide high precision and power transmission, and are essential in automation, lifting systems and control mechanisms. This also includes specialized tools for assembly and tension control.
Industrial fastening systems, locking bolts, tools and powerig
Mechanical and hydraulic fastening solutions as well as special tools such as Powerig for precise clamping and adjustment.
Gas springs
Springs used to open, close and balance industrial lids and panels. Also available in stainless steel and lockable versions.
Air multipliers / Airmover
Compressed air-powered devices to increase air flow or create vacuum. Used for cooling, dust extraction and ventilation in explosive or powerless areas.
Clamping tools
Hydraulic and mechanical tools for secure clamping and adjustment of industrial parts during assembly and maintenance.
Structural and fastening components
Structural and fastening components ensure interconnection, anchoring and support in technical installations and mechanical building systems. Typical applications include enclosures, sheet metal structures and fixed mounting of components. These parts are essential for stability, durability and safe operation in both fixed and mobile systems.
Industrial fastening systems
Solutions for mechanical assembly of components in buildings, production equipment and technical installations.
Punching details
Precision-made components manufactured through stamping – used in enclosures, panels and sheet metal structures.
Sheet metal fasteners
Fastening solutions for thin sheet materials that ensure strong and durable joining without welding or drilling.
Hose clamps – Hose clamp types
A wide range of hose clamps for industrial applications, including standard and specially designed types for high pressure, vibration or aggressive media.
