Powerful axial fastening with wedge effect, no key machining required.
The precision shaft coupling - compensation type (no key machining required) "UCN-T7 series" provides strong shaft fastening through a wedge effect, eliminating the need for key machining. It has a permissible eccentricity of 0.2mm, a permissible angular misalignment of 1°, and a maximum rotational speed of 6000r/min. While the allowable angular misalignment in use is 1°, structurally it can accommodate up to 3°. There are also model numbers available that can accommodate hole diameters other than the standard shaft hole diameter. For more details, please download the catalog.

Company information
Sakai Manufacturing Co., Ltd. began manufacturing and selling belt-type continuously variable transmissions in 1950. During the period of rapid economic growth, we achieved maintenance-free operation with transmissions that adopted oil-free mechanisms as a countermeasure against micro-wear, thereby expanding our track record. Subsequently, based on the theory of micro-wear countermeasures, we developed the coupling: Precision Correction Shaft Joint Series, which has been well received in the semiconductor and liquid crystal-related equipment market for its characteristics. Additionally, our plate spring-type coupling: Precision Spring Shaft Joint Series, which responds to the increasingly high performance of automatic control, has gained popularity in the machine tool sector. The rigid coupling: Precision Fixed Shaft Joint, which pursues precision during fastening, is attracting attention in the field of high-precision positioning equipment. Our company has been engaged in the development and manufacturing of products that meet the needs of high-precision and high-quality transmission devices, based on the fundamental philosophy of "providing excellent functional elements." Moving forward, we aim to be a company that contributes to societal development through the creation and provision of innovative and highly reliable products that reflect our customers' needs, while continuously striving for improvement.
