The product "SiC30" that we handle is manufactured by impregnating molten silicon into highly porous electrical graphite. When used as a hard sliding counterpart material for carbon materials, it significantly improves the blister resistance of the carbon materials. When combined with other products to be used as "soft carbon materials," it can completely prevent blistering. Furthermore, it has superior thermal shock resistance compared to various ceramics used in tribological applications. Additionally, since it contains no boron at all, it is suitable for applications in the production of silicon in the electronics industry. 【Features】 ■ Unique silicon carbide-graphite composite material ■ Excellent hardness, strength, and wear resistance ■ Outstanding emergency operation performance ■ Temperature fluctuation resistance ■ Very high blister resistance 【Applications】 ■ Pumps and compressors ■ Mechanical sealing *For more details, please refer to the PDF document or feel free to contact us.

We offer a wide range of carbon graphite and SiC used in bearing products for mechanical seal materials, pumps, and more. Features of our materials and products: 1. If you are considering use under extremely low humidity or dry conditions, we recommend our FH71 series. Additionally, the FH71 series is effective in reducing operational noise and heat generation. 2. For wet applications, we recommend the FH81 or FH91 series. The FH81/91 series can be selected based on your application from non-impregnated and resin/metal impregnated options. 3. Schunk Carbon Technology offers both room temperature sintered and reaction sintered SiC. CarSIK-SD → SSiC CarSIK-NT → SiSiC CarSIK-CT → SiSiC-C While we have a wide range of materials, if the product you are looking for is not in our lineup, we also propose developing new products in collaboration with our customers.

The characteristics of carbon and graphite used in carbon brushes can generally be judged from the items of "electrical resistivity," "hardness," "bending strength," and "bulk density." In the case of metal graphite, the metal content is also noted in addition to the above items. All data are averages. The testing methods and equipment generally conform to IEC60413. These values can vary significantly due to various environmental factors and operating conditions. Therefore, based on experience, we have established a general range for the values of the two items and compiled them into a table by category. Please refer to the PDF document below for confirmation. *For more details, please refer to the PDF document or feel free to contact us.*

Our CFRP sleeves secure the rotating assemblies of surface-mounted permanent magnet synchronous motors (SPM) and synchronous motors (ESM), minimizing eddy current losses. In addition to using reinforced carbon fibers with high tensile strength characteristics, our high level of manufacturing precision allows us to keep the wall thickness to a minimum. We can also produce sleeves with a wall thickness of 10mm or more, similar to CFRP flywheels. 【Customer Benefits】 ■ Reduction or elimination of eddy current generation ■ Capability to support high-speed motors ■ Weight reduction ■ Improvement in the aesthetic design of motor designs Schunk provides a consistent service from prototyping to evaluation. ■ Assembly planning ■ Conducting sleeve factor (FE) analysis ■ Prototype production ■ Test assembly and evaluation ■ Chemical resistance evaluation For more details, please refer to our brochure and video.
