Notice of Participation in EE Tohoku '23

An evolved hydraulic tensioner that overcomes the challenges of conventional tensioners, such as "too heavy," "does not fit in narrow spaces," and "oil leakage due to repeated use."

The hydraulic bolt tensioner from "Boltight," a member of the Nord-Lock Group, was born as an evolved version re-invented by the engineer Fred Heaton, who developed the tensioner itself, to overcome the challenges faced by the tensioner. These challenges include common disadvantages of hydraulic tools like tensioners, such as being "too heavy and difficult to work with," "leaking oil after repeated use," and "not being installable in confined spaces." All of Boltight's tensioners have been significantly lightweighted to the extreme, using in-house developed bridges and seals to greatly reduce the weight of the tensioner. Additionally, the durability for repeated use has been greatly improved with technologies such as in-house developed seals. Furthermore, we can flexibly customize the shape and size for areas where space constraints prevent application, delivering them with the same lead time as standard products.

Can be used as a replacement for existing pins. It significantly reduces the maintenance costs of equipment and is an innovative pin product that can be used universally on any moving part.

Wear occurring in movable parts is a major enemy of low-cost operation, requiring regular maintenance such as bush replacement and pin hole repair. For equipment manufacturers, it is an issue that cannot be overlooked, as it increases maintenance costs, which are a quality indicator of the machine, and shortens product lifespan. For machine users, it leads to chronic problems of high maintenance costs and downtime. The advantage of the Expander System is that it can be used semi-permanently and completely prevents wear in movable parts, eliminating the need to replace bushes like consumables. In movable parts that do not use bushes, it can eliminate oval deformation. The secret lies in the fact that after installation, the pin's axis expands in a way that completely seals the gaps inside the pin hole. The Expander System is already widely adopted by leading construction equipment manufacturers, including Japanese companies, and has passed a continuous field durability test of 60,000 hours without any loss of functionality at Volvo Construction Equipment. It comes with a lifetime warranty, guaranteeing the product's functionality until the first removal. *For more details, please download the catalog or feel free to contact us.

No allowance for loosening, securely maintain axial force! Physically prevent loosening of bolts/nuts.

This catalog introduces the "Nord-Lock Washer," which utilizes wedge-locking technology that physically prevents bolt loosening without relying on friction. It features the "Nord-Lock X Series Washers," which simultaneously prevent two types of loosening, as well as the "Nord-Lock SC Washers," designed for high-strength bolts used in construction. Additionally, it includes information on why bolts loosen and the Nord-Lock customer magazine.

An innovative product that can tighten enormous bolts and nuts that cannot be tightened by human strength using just one torque wrench.

A mechanical bolt tensioner developed in 1984 at the request of US Steel, the largest steel company in the United States. By distributing the enormous torque required to tighten large-diameter bolts into smaller torques, it dramatically improves work safety. Additionally, it achieves remarkably accurate fastening force, allowing for work in high or confined spaces without issues. The use of electric tools and air tools further shortens work time, dramatically reducing downtime caused by operations and enabling low-cost operations. 【Features】 ■ Amazing axial force accuracy due to patented structure (over three times the accuracy of conventional methods) ■ Large-diameter bolts can be fastened with just one torque wrench ■ Does not depend on the skill of the operator, ensuring accurate fastening force regardless of who performs the work ■ Incredible axial force precision prevents loosening even under severe vibrations ■ Strong against loosening that does not involve return rotation due to thermal cycles, thanks to elastic fastening ■ Usable without issues in confined or elevated spaces *For details, please refer to the catalog or contact Nord-Lock Japan. *Beware of imitations that resemble the appearance. They do not have equivalent functions due to patented technology. Nord-Lock Japan also provides various technical support. Please feel free to consult us.
