Product Introduction

The flexible bellows protective cover is fabricated by folding, sewing, or thermoforming nylon leather, plastic fabric, or synthetic rubber. Inside the bellows cover, PVC plates provide structural support, enabling it to withstand heat, oil, and coolant; it can endure instantaneous temperatures up to 1,000°C and incorporates insulated support plates. The travel speed can reach 100 m/min. Depending on customer requirements, in addition to the standard flat-type bellows design, the cover can also be manufactured with stainless steel inserts, as well as in circular, hexagonal, octagonal, and other configurations.

Product Advantages

● This type of shield features resistance to deformation upon impact by hard objects, long service life, excellent sealing, and smooth operation. Made from specialized materials, it is resistant to coolants, oil, and metal chips, while also offering a long travel range and minimal compression.

● The flexible bellows guard contains no metal components, so you can rest assured that no parts will loosen during operation, thereby preventing serious damage to the machine.

Schematic Diagram of Technical Parameters

Lmax = maximum tensile force of the guard shield

Lmin = minimum compression of the guard

S = travel distance

W = outer width of the guard shield

Wi = inner width of the protective shield

h = outer height of the guard

hi = inner height of the protective cover

H = Folding height of the guard

n = number of folds in the guard

D=Cover fabric

A=Protective Cover Frame

B=Flanges at both ends of the guard

H ≤ h − hi or H ≤ (W − Wi)/2 (for symmetrical installation on both sides); unless otherwise specified, the flanges at both ends of the guard shall be made of Q235 steel.
