The "Rocking Element" from Durimaittec is used to transmit power without the need for keyway machining on shafts and hubs. Since there are no keyways or notches, the strength of the components is increased, allowing for more efficient transmission of greater power. Additionally, axial position adjustments can be easily made. This significantly improves workability not only in manufacturing environments but also for designers, and the absence of notches in the components enhances their strength. The standard type is versatile and compatible with similar products from other companies, and we also have stock of special dimension elements beyond the standard type, making it very convenient. We offer a variety of forms, so please select and use according to your application. 【Features】 ■ High torque transmission possible without troublesome keyway machining on shafts and hubs ■ Significantly improved workability ■ Increased component strength ■ Compatibility with similar products from other companies *For more details, please refer to the comprehensive catalog or feel free to contact us.
