The "NB Slide Screw" is a unique drive device that effectively utilizes the friction between radial ball bearings and the shaft to convert rotational motion into linear motion. Due to its simple mechanism, maintenance is easy and installation is straightforward. While pursuing precise positioning may seem difficult, by fully utilizing the characteristics of the slide screw, it can be used in the transport sections of various devices. 【Features】 ■ Linear drive is possible with a round shaft ■ High mechanical efficiency ■ Can be used without lubrication ■ Overload prevention mechanism *For more details, please download the PDF or feel free to contact us.

As a comprehensive manufacturer of locking nuts, we equip our bolts with high-quality locking features. Even in areas where using nuts is difficult, you can ensure a secure fastening operation by using the "Fuji Lock Bolt N type."

A specialized U-NUT that facilitates work in locations where access is difficult, such as the installation of soundproof walls on highways. Simply drilling holes in the components eliminates the need for nut welding and screw tapping. Additionally, the guide ring function makes positioning easy. The one-sided fastening method reduces the number of workers required and achieves a total cost reduction.

In response to requests from various sources, we have integrated washers into the U-NUT. The integrated "U-NUT with washer" improves labor efficiency and increases work productivity. Additionally, it reduces the chances of forgetting to attach parts and simplifies inventory management.

We have introduced our U-NUT technology into blind nuts. The "BLU-NUT" eliminates the need for welding U-NUTs to square washers and preparing them as back nuts, preventing issues such as spinning and seizing, while also reducing work time. This "BLU-NUT" will lead to further improvements in our customers' work efficiency and cost management.

We protect facilities and equipment, including mega-solar installations made across the country, from theft and vandalism at important sites around the world. "SU-NUT" features a special design that enhances security effectiveness as a visual deterrent, and it cannot be attached or detached with commercially available sockets or wrenches; a dedicated socket is required. The management of the dedicated sockets is handled by our company, and we provide them to customers free of charge after signing a "memorandum."

The "GU-NUT" adopts a large 270° friction ring on the "U-NUT" to meet the loosening prevention performance specified in JIS B 1056. This enhances the loosening prevention performance and pursues further safety and peace of mind.

Since its establishment over 50 years ago, U-NUT has built a great deal of trust and achievements. It is active in various industries, ranging from cars, motorcycles, and industrial machinery to railways and steel structures like bridges. No matter how harsh the usage environment, U-NUT is required to provide safety and peace of mind. It continues to evolve as the definitive solution for locking nuts, not only in terms of anti-loosening performance but also in durability and vibration resistance.

Precision lock nuts are nuts used for securing bearings, and they can fully demonstrate their effectiveness in rotating bodies that require high precision. Rotating bodies are becoming smaller and faster, and there is a demand for high precision with minimal runout. In such cases, using high-precision lock nuts makes this possible and significantly reduces assembly time for equipment. Our precision lock nuts are manufactured to achieve runout precision of less than 3μm by simultaneously grinding the threaded part and its end face. Therefore, when the bearing end face is secured with the lock nut, it is possible to assemble with minimal eccentricity in the shaft part and achieve high precision. Additionally, the effective diameter of the threads is managed and manufactured towards the lower limit, which minimizes play with the shaft part when tightened, making it less likely to loosen due to vibrations. Furthermore, assembly and disassembly can be easily performed, making it very convenient for regular inspections, maintenance, and repairs of machinery.

It is a mechanical element that transmits the rotational motion of the screw shaft to the linear motion of the nut through a planetary roller. The number of contacts and the total contact surface area between the screw shaft, rollers, and nut are significantly increased compared to ball screws, making it a transmission element with extremely high dynamic and static load capacity. It can be used as a substitute for hydraulic drive systems due to its ability to handle high thrust. Based on its structure, there are mainly three types: rolled roller screws, precision roller screws, and circulating roller screws.

The seals for IKO needle bearings are low-profile seals made of a steel ring and special synthetic rubber. These seals are designed to match the profile height of IKO needle bearings, effectively preventing grease leakage and foreign matter intrusion by being directly incorporated into the sides of the combination bearings shown in the dimension table. When combining seals with inner ring needle bearings, it is necessary to use a wide inner ring.

IKO circlips for needle bearings are specially designed for needle bearings that often cannot use general circlips. They have a low cross-sectional height and high rigidity. The material used is spring steel. These circlips are available for shafts and holes and are used to position bearings to prevent axial movement.
