Have you ever felt that preparing to lift and transport heavy loads or machinery takes a lot of time? When performing lifting operations, eye bolts are generally used, but it actually takes about 20 seconds to install or remove each eye bolt. As the number of eye bolts increases, so does the time and effort required. Do you want to attach and detach more quickly? In such cases, using this "Threaded Clamp Type Lifting Pin" allows for easy attachment and detachment with the push of a button. The attachment and detachment time is just 3 to 4 seconds, which is significantly faster than using eye bolts. By enabling quick and easy attachment and detachment, it helps reduce the time and effort involved in operations, contributing to improved work efficiency and cost savings. Additionally, there are other benefits such as: - The ability to perform horizontal lifting, which is prohibited with eye bolts, expanding the range of transport operations. - Excellent corrosion resistance, with the stainless steel type also being weather-resistant for outdoor use. - High safety and performance, with a top market share in North America, including Germany as the manufacturing country (designed with a safety factor of 5 times). More details about the lifting pin can be found in the catalog. It is filled with exclusive technical information, so please take a look!

Have you ever felt that assembling bearings is complicated and difficult? In fact, during traditional bearing assembly, it was necessary to process a keyway on the screw part of the shaft and install a washer between the bearing and the bearing nut. When the process is complicated, work doesn't progress as smoothly as one would like. If you want to improve work efficiency, using this "Super Bearing Nut" can make the assembly process much easier. The biggest feature is that one Super Bearing Nut can prevent loosening. This eliminates the need for keyway processing and washers, contributing to a reduction in the total cost of the product, weight reduction, and improved workability. Additionally, there are other benefits such as: - Reusable - Extended lifespan of bearings - Improved rotational balance of the shaft - Possible to manufacture in small lots and short delivery times More details about the Super Bearing Nut are included in the catalog. It is filled with exclusive technical information, so please take a look!

Have you ever experienced the annoyance of chips being generated when attaching small screws to parts? Naturally, using them as is is extremely dangerous. Surprisingly, the generation of chips ranks among the top 10 causes of screw-related issues, and the occurrence and scattering of chips can lead not only to damage to the screw parts but also to injuries to designers. If possible, you want to perform fastening operations safely and securely, right? For you, we recommend a locking treatment for small screws. That is the "Tack N Ace"! By using this, you can capture the chips generated by friction during screwing with a special adhesive resin, while the compression and rebound force of the resin provides a powerful locking effect. It is especially ideal for use in electronic and electrical components that dislike the generation and scattering of chips and shavings, leading to long-term maintenance of product functionality and cost reduction. Additionally, by processing down to the seating surface, the resin can fill the gaps between the screws tightly, providing high sealing properties and waterproof functionality. For more details, please refer to the catalog. It is full of technical information, so be sure to take a look!

Don't you feel that the use of micro screws has increased during design and development? In fact, as the miniaturization of precision equipment progresses, the size of screws used is also getting smaller. To maintain product quality, even though they are small, measures to prevent screw loosening are essential. However, when it comes to preventing loosening, it's honestly unclear what to use... In such cases, we recommend 'Arock'! The key point is that the resin is fused to the bolt. The resin, which has high compressive and rebound force, compresses the gaps at the contact points of the screws and simultaneously creates a strong anti-loosening effect. Additionally, the anti-loosening effect is maintained at temperatures ranging from a minimum of -70°C to a maximum of 120°C, making it effective against vibrations, impacts, temperature changes, and heat, which are considered the main causes of loosening in micro screws, thus achieving prevention of loosening in a wide range of fields and components. Other benefits include: - Long-term management without worrying about expiration dates - Usable for more than five repetitions - Contains no harmful substances as it uses plant seed materials These advantages contribute to cost reduction, improved workability, and environmental measures. For more details about Arock, please refer to our catalog. It is filled with exclusive technical information, so be sure to take a look!

Have you ever felt that you want to use stainless steel but find it hard to justify the cost? While stainless steel excels in functionality, it is more expensive compared to other steel materials. You may want high functionality like stainless steel while keeping costs down. For you, we recommend "Raspart Zero-Stainless," a groundbreaking surface treatment that serves as an alternative to stainless steel. By layering two coats of corrosion-resistant coating over a zinc-nickel alloy plating, we can further enhance the corrosion resistance of the alloy plating, achieving high corrosion resistance comparable to stainless steel. This allows you to obtain nearly the same effects as stainless steel while using iron materials, thus enabling cost reduction. Additionally, it offers other benefits such as: - A thin film that provides good fit, eliminating the need for processing like over-tapping. - A finish that resembles stainless steel, excelling in decorative qualities. - Lubrication for screws, allowing for smoother work during driving and tightening. These advantages contribute to cost savings, improved workability, and maintenance of aesthetics. For more details on Raspart Zero-Stainless, please refer to our catalog. We invite you to take a look!

Have you ever felt that using anti-rust paint is quite cumbersome and troublesome? Conventional paints generally require two coats, with the first coat needing about 24 hours to dry, which also increases the amount of paint used. This leads to inefficient work progress and higher paint costs, making it very inefficient. You want to get the job done faster... For you, we recommend the anti-rust paint "Doral." Its greatest feature is that it provides high corrosion resistance and rust prevention with just one coat. It has excellent quick-drying properties, eliminating the need for the conventional two coats, thus improving work efficiency and reducing painting costs. More details about Doral are available in the catalog. It is filled with technical information, so please take a look!

The molten aluminum coating (i.e., aluminaize treatment) is a method that allows the aluminum in the surface layer to diffuse and penetrate into the base material using a "low-temperature diffusion method," achieving dimensional accuracy that was previously considered difficult with conventional molten coatings. This treatment is effective when improving corrosion resistance, heat resistance, and wear resistance for parts that require dimensional accuracy or surface hardness.
