If you need state-of-the-art round bellows that are manufactured to your exact requirements, then Nabell USA Corporation is set to serve you. Largely used for applications requiring complete protection, our range of round bellows are made to offer long service life even under extreme mechanical and dynamic stress. We, being one of the leaders in bellows manufacturing, supply round bellows in several sizes, as well as, materials to meet your application requirements and environments. They can be robust in design, resistant to coolants, oils, dirt, debris, weld splatter, metal chips and sawdust, among others.

Types of Round Bellows

  • RF Welded Bellows: Offering the best compression ratios, RF welded bellows are suitable for applications requiring liquid-tight protection.
  • Wire Insert Bellows: Looking for round bellows for applications wherein impact or crush resistance is a primary concern? Positive/Negative pressures a concern? Then go for wire insert bellows, which can be customized to various specifications.
  • Sewn Shape Bellows: Manufactured to withstand low/high temperatures, coolants, solvents, oils, weld spatter and more these types of round bellows perform well in the most challenging industrial environments.

Many of our round, oval or U-shaped bellows can be manufactured to incorporate:

  • Zippers
  • Limit Tape (side tabs) to prevent overstretching
  • Cuffs
  • Flanges
  • Bolt holes
  • Vents
  • Grommeted support tabs
  • Interior/exterior metal rings
  • Sealed seams
  • Double stitching
  • Stainless steel band clamps for cuffs
  • PVC stiffeners
  • Chemical resistant spray coating
  • Wire stiffeners and supports

Made to offer higher durability and greater abrasion resistance, round bellows can be used on or act as:

  • Lead screws, precision shafts, moving air cylinders
  • Cylinder Rod boots
  • Ball Screw or spindle protection
  • Shift/joystick boots
  • Lift table skirting
  • Robotic arms, satellite antenna jack screws, and patient tables.
  • Hydraulic Cylinder
  • Gaps in Duct-work
  • Screw Jacks and Actuators and exposed machinery
  • Food processing machine
  • Pharmaceutical processing machine

Certifications

With over forty-seven years of world-class design and manufacturing experience, compliance and certification requirements have become a “norm” for us and the industries we serve. We utilize ISO 9001:2015 as our Quality Management System and meet or exceed many standards such as; REACH, RoHS, COC, FAIR CONFLICT Minerals, UL94 VTM-0 (flame-resistant test) and many other special requirements from our customers.

Made from Polyurethane sheets, RF Welded bellows offer the best compression ratios of our round bellows and are completely sealed to provide liquid-tight protection. We offer several sizes with standard sleeve or flange ends, and offer Polyurethane with static dissipative properties for high clean room requirements.

Our Wire Insert bellows can be used anywhere where impact resistance is a primary concern, and are useful where positive or negative environmental pressures are present. We can manufacture Wire Insert bellows with customizable sleeves on the end or mounting flanges.

Our Sewn Shape bellows resemble our RF welded bellows in that they can achieve excellent ratios. They are highly customizable and can be manufactured from a wide range of materials to suit many different applications. For bellows that come in contact with high temperatures, coolants, solvents, or oils we feature neoprene, silicone glass cloth, and other special materials.
