These are used when strong rotation resistance is required (for instance, to cover ball screws) and where a very compact closed lenght is required.

  • Highly reliable bellows
  • No tooling costs
  • High resistance to mechanical and dynamic stress
  • With selected edging (in safety colors upon request)
  • Resistance to coolants and oils
  • Minimum internal diameter starting at 20 mm
  • Suitable for high temperatures
  • Any size external diameter
  • Available with guide bushings and reinforcement rings
  • Good price/quality ratio

Formula for calculating the CLOSED LENGTH

Note: When steel rings are required inside the folds, the P.C. is calculated by our engineering department.
