In response to our customers' requests, we have newly added two sizes to our lineup for high-torque motors!
The "Starflex STW" is a simple structure elastic coupling that uses polyurethane elastomer in the element section. With a significant improvement in "shaft holding power" due to the optimal design of the clamp hub, it achieves a "30% increase in transmitted torque" compared to the conventional ALS model. Additionally, we offer three models of elements based on their characteristics, allowing for a wide range of applications. 【Features】 ■ Improved shaft holding power due to the optimal design of the clamp hub ■ New lineup of high-torque models in two sizes ■ Three types of elements *For more details, please download the PDF or feel free to contact us.

basic information
【Lineup】 ■STW(ABN) Type: The element (polyurethane elastomer) uses a hardness of 97 JIS A, and its shape features a loose fit structure with a crowning shape on the torque transmission surface of the element, allowing it to absorb large misalignments with high torque transmission. ■STW(ARN) Type: The element (polyurethane elastomer) uses a hardness of 97 JIS A, and its shape is designed as a tight fit structure with pre-compression, enabling use without backlash. ■STW(AYN) Type: The element (polyurethane elastomer) uses a hardness of 90 JIS A, and its shape is designed as a tight fit structure with pre-compression, enabling use without backlash. *For more details, please download the PDF or feel free to contact us.
