KT-Guide Elements: Developed
and Manufactured by Specialists!

Precision-Engineered. Technically Sophisticated. Reliable in Operation.

For over 40 years, S.F. Components has been developing KT-Guide Elements for use in hydraulic systems.

As experts in the field of KT-Guide Elements, we manufacture products for you to the highest standards, using state-of-the-art CNC technology, material expertise, and many years of experience, all while meeting the highest quality requirements. Our manufacturing expertise is the key to precision and offers a high degree of flexibility and reliability.

High Technical Standards

Each guide element is manufactured precisely to technical specifications, meets the high load requirements of modern hydraulic systems, and ensures the precise guidance of pistons and piston rods in hydraulic and pneumatic cylinders.

Variety and Quality of Materials

Thanks to a wide range of high-performance materials combined with state-of-the-art technology, our guide elements reliably absorb lateral loads, even under high operating loads. They prevent metal-to-metal contact between components and ensure smooth, efficient operation.

Our Mission

As specialists in KT-Guide Elements, we offer optimal solutions for a wide range of applications and industries by combining innovative materials, expert advice, and state-of-the-art engineering. Our guide elements are available in a variety of designs and materials to ideally meet any specific needs.

Manufacturing Expertise That Makes a Difference

Our guide elements are available in a variety of designs: in various material combinations, as ready-to-install rings, by the meter, in spools, or preformed into a spiral shape.

Some of our material combinations are treated with special lubricants to improve friction characteristics and reduce breakaway force. You can find an overview of materials and designs here.  

Thanks to their outstanding material properties, our versatile materials are perfectly suited for use in hydraulic systems across a wide range of industries and technical applications.
