In challenging applications in mechanical engineering, components made from aluminium or steel quickly reach their limits. Carbon fiber composites make it possible to advance into new dimensions in the performance of machines and hence the production sites.
SGL Carbon's semi-finished and finished products offer high strength and rigidity as well as good damping behavior. Thanks to the wide range of matrix and carbon fiber materials that can be combined with each other, our SIGRACOMP® CFRP components can be manufactured with material properties that are individually tailored to the task at hand. Typical SIGRACOMP® CFRP components are rapiers, connecting rods, lifting beams, bunching bows, and tool axles.
Their self-lubricating property and extreme consistency make our SIGRAFINE graphite products ideal components in a wide range of applications. These range from rotors and vanes for compressors, commutators, and sliding bearings and seals for fuel pumps to sliding bearings for kitchen ovens.
We can implement pressed-to-size technology (PTS) in many areas: Near-net-shape pressings make it possible to manufacture complex component parts in large numbers at low materials usage. Since mechanical end machining is entirely or largely unnecessary, this process is especially cost-efficient.
Take advantage of our application-technical expertise. We are glad to advise you on how to optimize your processes and will work with you to find specific solutions to your needs.
Here you will find a selection of components from our portfolio for applications in mechanical engineering.

In high-tech applications requiring high strength and stiffness combined with light weight, our carbon fiber-reinforced plastic (CFRP) components are indispensable. The properties of CFRP materials bring to bear precisely when other materials reach their limits. CFRP is considerably lighter than aluminum or steel, while being extremely durable.
Steam-admission head rings made of graphite and carbon graphite are particularly low-wear and resistant to high temperatures and aggressive gases. In addition, their excellent sliding properties ensure low-wear and low-noise operation.
End plates made of special graphite offer advantages as counterparts to friction reduction. In addition to outstanding temperature resistance and a low coefficient of expansion in the event of temperature fluctuations, weight savings can also be achieved thanks to the low density of carbon.
Our bearings and high performance sliding rings are made of graphite, carbon graphite and expanded graphite. The material makes them extremely resistant to both high temperatures and aggressive gases and superior to other materials. In addition, their excellent sliding properties ensure low-wear and low-noise operation.
The low-wear packing rings with metal jacket from SGL Carbon are extremely resistant to both high temperatures and aggressive gases and are superior to other materials. In addition, their excellent sliding properties ensure low-wear and low-noise operation.
Rotors made of specialty graphite are characterized by particularly high mechanical strength and very good sliding properties. Tight manufacturing tolerances and a low coefficient of friction help to ensure efficient use. They can be milled for small quantities or produced in a cost-efficient pressed-to-size process for large series.
Vanes made of specialty graphites and hot pressed carbon materials are characterized by particularly high mechanical strength, very good sliding properties and breaking strength. The lubricant-free use offers additional freedom in design and very good emergency running properties.
Carbon fibers and their composites
Our carbon fibers as well as our textile, pre-impregnated and thermoplastic fiber composite materials are ideal for producing stiff, strong and ultra-lightweight components for demanding high-tech applications.
Outstanding mechanical, thermal and chemical properties - foremost its self-lubricating behavior – make our specialty graphite the go-to choice for a multitude of mechanical-engineering applications.
