Type HSL/HBL/WSL Bellows

Features

  • Welded bellows: Thin metal sheets that are formed in a precise circular shape, with the inner and outer diameters specially welded to each other. Suitable for fields where particularly high precision is required or where the conditions of use are severe.
  • Formed bellows: Thin metal tube formed into bellows with high hydraulic pressure from inside, featuring mass-producibility and quality stability.
  • Welded bellows for vacuum applications: Welded bellows for low pressure, high vacuum, and extended strokes. Uses corrosion-resistant SUS316L, and end fittings allow for easy installation.

Applications

Semiconductors, aviation, ships, automobiles, chemical industry, refrigeration, air conditioners, electrical facilities, civil engineering and construction, medical, instrumentation, textiles, agriculture and livestock, pulp industry
