『U-NUT』『FINE U-NUT』『TWIN FU-NUT』
Safety and security lock nuts "U-NUT" and "FINE U-NUT" are available in a variety of sizes and shapes.
"U-NUT" and "FINE U-NUT" are adopted in various medical devices such as wheelchairs and digital panorama X-ray imaging equipment. "U-NUT" is a locking nut that is active in various industries ranging from cars, motorcycles, and industrial machinery to steel structures like railways and bridges. "FINE U-NUT" is a locking nut specifically for bearings used in rotating shafts of industrial machinery such as ball screws and spindles. We offer a rich lineup including the reliable locking nut "U-NUT" that ensures secure fastening, and the bearing locking nut "FINE U-NUT" that eliminates the need for traditional keyway machining of shafts and the installation of toothed washers. We also have the precision lock nut "TWIN FU-NUT," which further enhances the locking performance of FINE U-NUT with two friction rings. We also accept orders for custom shapes. 【Product Lineup】 ■U-NUT ■FINE U-NUT ■TWIN FU-NUT *For more details, please refer to the PDF materials or feel free to contact us. *3D CAD data is also available for download.
basic information
"Metal Ring Loosening Prevention Function" Structure: The "U-NUT" and "FINE U-NUT" consist of two parts: the nut body and a friction ring (special spring), with the friction ring integrated into the top surface of the nut through a riveting process. Function: The force generated by the elasticity of the friction ring, along with the force that pushes against the male thread flank, creates a pre-torque (friction torque) that exhibits the loosening prevention effect.
