"Metal bellows" expands and contracts with a bellows structure, achieving both flexibility and airtightness!
It can be stretched or bent in the axial direction! For movable units and joints that require flexibility and airtightness.
"Metal bellows" are products formed using metals such as phosphor bronze and stainless steel, featuring corrugated folds in a tubular shape, providing elasticity, airtightness, and spring properties. "Bellows" refers to the English word meaning "accordion" in Japanese, resembling the bending parts of an accordion or a straw. 【Features of Metal Bellows】 ■ They have a structure that allows for axial expansion and bending, excelling in airtightness, elasticity, and pressure resistance. ■ Stable mass production is achieved through collaborative automatic production with original molding machines and skilled technicians. ■ Small-lot, diverse production is possible, starting from just a few pieces. ■ Bellows can be manufactured according to design specifications, including material, plate thickness, number of waves, spring constant, and end shape. ■ We also support the assembly (ASSY) of bellows, reducing and streamlining operations through the consolidation of orders. *For more details, please refer to the PDF document or feel free to contact us.
