Ceramic parts, which possess performance that cannot be matched by metals, are chosen for designs that require high-temperature environments and insulation properties. This product made of alumina not only has heat resistance up to 1300°C but also boasts high insulation, non-magnetic properties, and chemical resistance, providing stable performance even in harsh environments such as electronic devices, semiconductor equipment, and optical instruments. For challenges such as "not wanting shape changes at high temperatures," "avoiding electrical interference," and "needing resistance to chemicals and corrosion," we offer solutions starting from small spacers, washers, and even a single screw. As a lightweight alternative to metals like stainless steel, we contribute to weight reduction. We have a diverse lineup of shapes, including hex bolts compatible with gas venting and nuts that utilize insulation properties. Please consider us as a solution for thermal design challenges. *For more details, please download the materials or contact us.*

■Resin (Insulation) Bushings At Hiroki Sugeki, we offer a wide variety of "resin bushings," essential for protecting bearing parts and mounting holes, as well as for insulation measures, with over 3,000 items, making us a top player in the industry. From highly versatile Duracon and ABS to high-heat and high-strength PEEK, and chemical-resistant PTFE and PPS, we can meticulously select the optimal material according to the installation environment. In addition to standard "bushings," we also provide "flanged bushings" that enhance the stability of the seating surface, ensuring precise responses to design requirements down to the millimeter. ■Case Studies and Problem Solving By introducing resin bushings, we can efficiently solve design challenges such as the following: - Insulation measures against metal contact: By inserting a bushing between metal screws and metal housings, we can reliably prevent electrical short circuits. - Reduction of friction and smooth operation: Utilizing the low friction coefficient properties of PTFE and Duracon, we minimize wear on sliding parts and extend the lifespan of moving mechanisms. - Weight reduction and cost reduction: By replacing metal bushings, we achieve both overall weight reduction and cost optimization for the product. - Chemical and environmental resistance: With PEEK and PPS, we can accommodate industrial equipment that requires exposure to chemical substances or use in high-temperature environments.

At Hirose Instrument Co., Ltd., we offer a variety of "metal bushes" that are ideal for sliding parts under load and fastening parts that require high tightening torque, available in diverse materials and surface treatments. In areas where resin bushes lack rigidity or in environments requiring long-term wear resistance, our metal bushes demonstrate stable performance unique to metal. We cover a wide range of standards from standard M2 to M6 (inner diameter φ2.0 to 6.5), allowing for the selection of optimal materials and treatments tailored to design intentions. ■ Advantages of Using Metal Bushes High tightening resistance: Being made of metal, they are less prone to deformation even when tightened with higher torque compared to resin, maintaining stable fastening strength. Excellent dimensional stability: They are hardly affected by temperature changes or humidity, allowing for precise sliding and mounting accuracy to be maintained over long periods. Diverse surface treatments: Various plating and anodizing treatments can add characteristics such as corrosion resistance, surface hardness, and conductivity, meeting the detailed design requirements of each product. ■ Customization and Support We also accept modifications of standard sizes (such as flange pressure, length, bush diameter, effective length, etc.) and the production of custom items based on drawings.
