Round bellows are used to protect cylinder rods, smooth or splined shafts, joints, screws (ball, trapezoidal …) solar trackers …. Their main advantage is that they need little space for the compression.
We have a wide variety of materials with which to protect from dust, water, acids, abrasives, projections, high temperatures (up to 1500ºC), etc….
We can manufacture them with a longitudinal opening that allows their quick and easy installation without having to disassemble the piece to protect.
At Proteval we have extensive experience in the manufacture of round bellows for solar trackers.
