Elastic joint using barrel springs (barrel-shaped coil springs).
Lightweight and strong, easy to install, stable, longer lifespan, maintenance-free. The IUS-B Hasek Gear Coupling is a lightweight, strong, and easy-to-install coupling that requires no maintenance. It uses materials such as hub (S45C) and sleeve (Tenac 5010 resin), making lubrication unnecessary.

basic information
【Features】 ○ Cushions impact torque due to deformation of the barrel spring. ○ Reduces peak torque to 60-70% compared to fixed couplings such as gear couplings and disc couplings. ○ Damps torsional vibrations early due to friction between the wire strands of the barrel spring. ○ The barrel spring is shrink-fitted onto the pin, ensuring that the contact area is completely backlash-free and has high positional accuracy. ○ Suitable for high-speed rotation simultaneously with disc-type couplings. ○ Allows for adjustment of all axis alignments—eccentricity, angular misalignment, and axial direction—with a single coupling. ○ The barrel spring requires no inspection for about two years after lubrication during installation. ○ The reference surface is flange-shaped, making alignment easy. ● For more details, please refer to the catalog or contact us.

Company information
Since our establishment in 1970, we have continued to develop new couplings. We challenge ourselves to determine "what is the optimal shaft coupling" for various mechanical devices across a wide range of fields. Considering the original functions of couplings, additional features, and the environmental conditions surrounding mechanical devices, our customers' requirements are diverse. Our 35 years of experience serves as the foundation for providing "optimal couplings" that meet these varied demands. We design products tailored to customer needs based on compact power transmission couplings with excellent torque transmission, safety, and durability, as well as power transmission mechanisms developed by our company and standardized components. The technology accumulated by our specialized manufacturer over many years allows us to respond to all requirements through a combination system of standard and custom parts. We have operated under the concept of being a "coupling manufacturer that responds kindly and carefully to customer needs." Thanks to this, we have gained strong trust, and our products are in operation at many sites, including steel manufacturing machinery. Moving forward, we will shorten the lead time from design to shipment to "provide products that match customer requirements in a timely manner." We are committed to growing into a manufacturer of value for our customers, and we sincerely ask for your continued guidance and encouragement.
