Bellows

Bellows

Rubber bellows are widely used in the mechanical seal industry where the bellows acts as a spring element that ensures proper sealing. They are made of rubber and are used to keep moving mechanical parts free of dust and moisture. It enables the rubber bellow to expand and shrink while maintaining a tight seal. A secondary dynamic seal is not required for this design. Because it is a static secondary seal that stays in place against the shaft, sleeve, or gland of the pump, Bellows Mechanical Seals are also known as non-pusher seals.

Summary / Key Takeaways

Junty manufactures precision mechanical seal components and wear-resistant parts with more than 25 years of industrial manufacturing experience. This product page at product / bellows covers seal rings, bushings, bearings, rotary unions, and four core engineered material families: silicon carbide, tungsten carbide, carbon graphite, and advanced ceramics.

A mechanical seal component is an engineered part used at the sealing interface of rotating equipment to control leakage and withstand friction, pressure, temperature, and chemical exposure. Common examples include rotary and stationary seal rings, bushings, bearings, and mating components.

Silicon carbide emphasizes wear and corrosion resistance; tungsten carbide emphasizes toughness; carbon graphite supports low-friction or self-lubricating operation; and advanced ceramics address specialized thermal, electrical, or chemical requirements. Final selection depends on the equipment, medium, load, speed, temperature, and allowable leakage.

  1. Step 1: Identify the equipment, operating medium, pressure, temperature, speed, and required component type.
  2. Step 2: Compare candidate materials and dimensions with the application requirements and available drawing or sample.
  3. Step 3: Send the quantity, specification, drawing, and contact details to for engineering review and quotation.
