Leave it to us for precision shaft couplings and supplementary forms!
The precision shaft coupling - standard type (unmachined shaft hole) "UCR series" is an unmachined product. It has a permissible eccentricity of 0.2mm, a permissible angular misalignment of 1°, and a maximum torque of 5 to 1280 N·m. While the allowable angular misalignment during use is 1°, it can structurally accommodate up to 3°. The maximum torque is the instantaneous torque that can be transmitted during startup and braking.

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.
