"Tribology Friction and Wear Testing Machine" Solving the challenges of friction, wear, and lubrication in tribology!

Friction, Wear, Lubrication: Solving Tribology Challenges! Compliance with Standard Tests / Reproduction of Operating Environments / Performance Quality Evaluation

At Yokoyama Manufacturing, we handle products that conduct various tribology tests. The evaluation of tribology requires assessments under new materials and actual usage conditions, and the specifications for testing machines are becoming increasingly specialized. Utilizing our experience based on past custom achievements, we realize cutting-edge evaluation and testing environments. ■ Tribology Testing Machines for Material Evaluation These testing machines measure important parameters such as the coefficient of friction and wear amount for sliding and rotating components. They comply with standard tests specified by JIS, ISO, and others. We also offer various options for testing environments, such as oil baths and heating. ■ Tribology Testing Machines for Product Evaluation Tribological evaluations of sliding and rotating components like bearings and bushes require tests under conditions that closely resemble real environments. We provide testing machines that conduct tests under conditions that closely replicate the product's usage environment. ■ Tribology Testing Machines for Lubricating Oil Evaluation Tribological evaluation is essential for assessing the performance and quality of lubricating oils. We also manufacture and sell various testing devices for the research and development of lubricants (oils and greases).

The Ministry of Land, Infrastructure, Transport and Tourism has initiated various construction projects, and safety management and improvement of working conditions during the extreme heat of summer have become significant themes at civil engineering sites. Even as the concept of summer work stoppages spreads, it is important not to rely solely on stoppages but to focus on innovative temporary materials to improve daily site conditions. Hyper CLT sheets are civil engineering materials that utilize wooden CLT. They can be used in various civil engineering sites as a substitute for steel plates, including temporary roads, access routes, heavy machinery work yards, material storage areas, and pedestrian pathways. The 5×10 sheet weighs approximately 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to handle with small machinery, which helps reduce the burden of installation and removal. Thanks to the unique properties of wood, these sheets can help minimize glare compared to steel plates, making them useful for heat stroke prevention measures and environmental considerations during the summer. Additionally, they are expected to provide benefits in terms of construction efficiency and site environment, such as improved transportation efficiency and noise reduction. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS "TH-250021-A," they are also recommended for creative proposals in public works. Please consider them as a new option for civil engineering sites looking to address heat-related issues, including summer work stoppages. We also accept inquiries for consultations on implementation tailored to site conditions and requests for materials. We can provide proposals for public works and private civil engineering projects both within and outside Okayama Prefecture. Please feel free to contact us.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching doorknobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot in front of it. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with a wide opening, vertical beam type "PF-01S" ○ Slim type with a wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.

In recent years, as infectious diseases have spread, there has been a demand for products that enable "contactless operation," and this trend has extended to environments where automatic doors were previously operated by touch switches. As the automation of doors and the non-contact operation of automatic doors become more widespread, do you have any of the following concerns? ☑ Although we have introduced automatic doors, they remain open due to people crossing frequently in busy areas. ☑ We implemented touch switches to reduce unnecessary opening and closing, but we are concerned about hygiene. ☑ Touch switches require battery replacements regularly since they are powered. The light beam touch sensor "HA-T401" allows automatic doors to open and close without physical contact, and its compact detection range makes it suitable for narrow passages and high foot traffic areas, contributing to energy savings and infection control. 【Benefits of Implementation】 ○ Adaptable to various door types with four different spot settings, ideal for busy roads and narrow passages. ○ Energy-saving effect with two setting modes that reduce unnecessary opening and closing of automatic doors. ○ Equipped with a light beam touch function, allowing doors to open and close simply by waving a hand, ensuring hygiene. ◎ For more details, please download the catalog or contact us.
