The "UCB" is a bearing developed with the aim of simplifying the structure and improving cost-effectiveness by lowering the bearing height and reducing the number of components. The lineup includes the fixed type "UCB-F," the omnidirectional movable type "UCB-M," and the right-angle fixed type "UCB-MF." Due to its low bearing height, it fits easily into existing space under beams. Additionally, the reduction in the weight of the bearing itself improves workability during handling. 【Features】 ■ The low bearing height allows for easy fitting into existing space under beams. ■ The reduction in the weight of the bearing itself enhances workability during handling. ■ The outer circumference of the HiPS is covered with rubber to ensure durability against rust. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Laminated Rubber Bearings" handled by BBM Corporation. Depending on the type of intermediate reinforcement steel plate, there are two types: flat plate type and ring plate type, which can be selected according to the application. To respond to the diversification of bridge types and construction conditions, our company has conducted various inventions, improvements, and experiments, and now possesses the technology to accommodate a wide range of bridge forms and construction methods, along with many achievements. 【Product Lineup】 ■ Flat Plate Type ■ Ring Plate Type *For more details, please refer to the PDF materials or feel free to contact us.

"HiPS" is a movable rubber bearing device composed of upper and lower steel plates that are processed into a concave shape, with rubber sandwiched in between. The rubber contains a donut-shaped internal steel plate (ring plate) embedded in its center. Additionally, a PTFE sliding surface is vulcanized and bonded to the upper part of the upper steel plate. When a compressive load (vertical force) is applied, the upper and lower steel plates and the ring plate constrain the deformation of the rubber, resulting in a structure that provides a large supporting force. 【Features】 ■ High structural performance that reduces bearing costs ■ Compact design ■ Structure that provides a large supporting force *For more details, please refer to the PDF document or feel free to contact us.

The "BB Stopper" can be used as a movement restriction device with high reaction force and large elongation capacity. In PC girders, large anchor bars and caps can interfere with the upper structure's reinforcement, but this product has minimal interference. Additionally, it is easy to consolidate the number of installations, reducing concerns about individual impacts. 【Features】 ■ Can be used as a movement restriction device with high reaction force and large elongation capacity ■ No cross-section loss occurs when the upper structure is a PC girder ■ Minimal interference ■ Easy to consolidate the number of installations ■ Reduced concerns about individual impacts *For more details, please refer to the PDF materials or feel free to contact us.

• Bridge Materials

The "HB Coat" is a coating agent that protects against cracks caused by ozone degradation of the rubber surface covering of rubber bearings, as well as prevents ozone cracks. For relatively large cracks, the "HARD type" is applied, while for smaller cracks such as hairline cracks, the "SOFT type" is used. If carried during bridge inspections, it allows for on-site repairs during the inspection, eliminating the need for separate repair work later. 【Features】 ■ Developed for rubber bearings with excellent elongation properties ■ Superior adhesion to rubber ■ Two types available for different applications ■ One-component type that requires no mixing ■ Easy for anyone to use *For more details, please refer to the PDF document or feel free to contact us.

• Safety and consumables

"FxSB" is a rubber bearing device specialized for fixed supports. Since it uses a bearing pressure stress of about twice that of laminated rubber bearings (25N/mm²), the planar shape has been reduced, and due to the low height of the rubber, the overall design has been made compact. 【Features】 ■ Simple ■ Compact ■ Low cost *For more details, please download the PDF or feel free to contact us.
