Solid shaft magnetic ferrofluid vacuum feedthroughs feature extended shafts on both the atmosphere and vacuum sides (with different diameters), allowing for direct installation of pulleys or couplings for efficient power transmission. MoreTec offers a fully integrated design and production system, with all key processes—including heat treatment—conducted in-house to ensure precision and reliability. Equipped with advanced precision machines from Japan, and supported by stringent dimensional inspections and dual leak testing (helium and pressurization), MoreTec ensures outstanding product quality. Standard lead times are as short as 45–60 days, providing customers with high-quality, responsive, and customizable sealing solutions.
Hollow shaft magnetic ferrofluid vacuum feedthroughs feature a hollow shaft design, allowing users to insert different center shafts based on their specific equipment needs. This flexible structure enables efficient power transmission and sealing, while also reducing material variety and inventory costs. MoreTec operates an integrated in-house design and production system, with all key processes—including heat treatment—handled internally to ensure precision and consistency. Equipped with high-end Japanese manufacturing equipment and rigorous quality control processes, including dimensional inspection and dual leak testing (helium and pressurization), MoreTec delivers superior quality. Standard lead times are as short as 45–60 days, offering customers fast, reliable, and customized sealing solutions.

Backed by decades of experience in ferrofluid and feedthrough customization, MoreTec provides strong R&D and engineering support. With a fully integrated in-house production system—from design and machining to heat treatment—we ensure stable performance and reliable quality. Our facility is equipped with advanced Japanese machinery and applies rigorous dimensional checks and dual leak testing (helium and pressurization) to ensure consistency and superior sealing performance. Standard lead time is only 45–60 days, meeting the dual demands of high quality and fast delivery.
MoreTec magnetic ferrofluid feedthroughs are widely adopted in high-end vacuum applications such as semiconductors, thin-film coating, and scientific research, offering the following key advantages:
Ultra-High Vacuum Sealing
With advanced ferrofluid formulation and sealing design, our feedthroughs can operate stably in ultra-high vacuum conditions up to 1×10⁻⁹ Pa, with no outgassing or particle generation.
Sealing Against Reactive (Corrosive) Gases
Equipped with specially formulated fluorinated ferrofluid, our feedthroughs maintain long-term stability in harsh environments involving reactive or corrosive gases, ideal for plasma and etching processes.
Low Startup Torque
Even in low-temperature conditions, our products maintain low startup torque, ensuring smooth and reliable operation under demanding conditions.
Exceptional Service Life
Proven in Japan: some of our feedthroughs have been operating continuously for over 10 years and are still functioning reliably, demonstrating outstanding durability and performance.
High-Temperature Capability
Designed to handle high-temperature environments, including those where water cooling is not possible, using customized magnetic fluids and thermal-resistant structures.
Backed by a fully integrated design and manufacturing system, precision Japanese production equipment, and a rigorous quality control and traceability process, MoreTec delivers high-performance feedthroughs with excellent quality and fast lead times, earning the trust of global customers.
