The "MINEX-S" is a synchronous rotating type magnetic coupling that transmits torque through the magnetic force generated between the inner rotor and the outer rotor. Since torque is transmitted without contact between parts, there is no wear on the components. Therefore, it is suitable for clean rooms, food machinery, packaging machinery, and other applications where wear particles can be problematic. The drive side and the driven side are separated by a containment shroud (partition), allowing it to be used as a sealing component in pumps and stirrers. Because it does not wear due to contact with rotating parts like mechanical seals or gland packing, it can reduce maintenance time and costs. It also demonstrates high sealing performance when handling hazardous fluids such as strong acids. 【Features】 ■ Synchronous rotating type ■ Can be used as a sealing component in pumps and stirrers ■ Complies with ATEX directives (explosion-proof directives), making it usable in hazardous areas ■ Special designs such as disk types can also be manufactured *For more details, please refer to the PDF document or feel free to contact us.

EVOLASTIC is a highly flexible, backlash-free flexible coupling that allows for the connection of shafts and flanges. The preloaded elastomer absorbs torsional vibrations and shock loads in the drive system. It also efficiently dampens solid-borne sound while simultaneously absorbing misalignments (axial displacement, parallel displacement, angular displacement) that occur between the driving and driven machines. The elastomer, an important component, is shaped into a ring by vulcanizing and bonding rubber and metal. The permissible temperature for natural rubber types (WN, SN, MN) is up to 90°C, while for EPDM types (WE, SE, ME) it is up to 110°C. It is possible to select different rubber hardnesses without changing the size of the coupling. The basic design is broadly categorized into bolt-connected types and plug-in types. Hubs and hubs, or hubs and flanges, can be combined according to the mounting dimensions of the driving and driven machines. This allows for flexible responses to various mounting dimension requirements. *For more details, please download the PDF or feel free to contact us.*

In the pharmaceutical industry, equipment durability and cleanliness are required in environments where chemicals and solvents are used. The BoWex resin gear coupling, which employs gears made of polyamide resin, excels in chemical and oil resistance, contributing to the maintenance of a clean environment. [Application Scenarios] - Rotating equipment such as pumps and fans in pharmaceutical factories - Maintaining equipment durability and cleanliness in environments using chemicals and solvents - Preventing equipment failure due to corrosion and wear - Reducing maintenance effort and costs [Benefits of Implementation] By using the BoWex resin gear coupling, you can contribute to improving the durability and cleanliness of equipment in pharmaceutical factories. The resin gears, which excel in chemical and oil resistance, prevent corrosion and wear caused by chemicals and solvents, extending the lifespan of the equipment. Additionally, they are maintenance-free and do not require lubrication, leading to reduced maintenance effort and costs!

GEARex is a metal (all-steel) gear coupling that complies with AGMA standards. It transmits high torque while absorbing misalignment (axial displacement, parallel displacement, angular displacement) that occurs between connected shafts. The combination of gears with a crowning shape and grease lubrication significantly reduces gear wear during torque transmission. With a design that combines high torque transmission performance and excellent durability, it is suitable for a wide range of applications across various industrial fields! The standard design is for horizontal mounting, but we can manufacture vertical mounting options upon request. We offer optimal couplings tailored to your needs, including types with brake discs, intermediate shafts (spacers), and shiftable link couplings. For more details, please refer to the catalog. Feel free to contact us with any inquiries.

A new lineup, "ROTEX GS ZRS," has been added to the widely used ROTEX GS in work machines, FA devices, and more. This series, designed with applications such as conveyors in mind, offers five sizes ranging from GS 19 to GS 42. Made with aluminum spacers, it is lightweight and has a low moment of inertia, while KTR's unique design achieves high torsional rigidity. It contributes to high-precision operation even in servo-driven applications where synchronization is required. Additionally, with a double cardanic structure featuring spiders positioned in two places, it allows for a large misalignment tolerance. The design also incorporates a damping resin spider, which helps reduce the load on surrounding equipment such as bearings.
