The function of a guide band (also called wear bands, wear rings, guide rings, guide bands, or bearings) is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
Our manufacturing process envolves the complete line, starting with phenolic-resign plus woven fabric, resulting in finished wear-rings, bushes or bearings, with excellent tolerances. This procedure includes prepreg-fabrication, tube-production on modern winding machines and the use of CNC revolving automatons, each step accompanied by careful quality control. For this reason, we are able to react fast and flexible to special requests of our clients with respect to dimensions.
Standard range of dimensions and tolerances:
Inside diameter: 18 mm - 520 mm Width: from 3 mm
Wall thickness: 1,5 mm - 25 mm Tolerances: 0,03 - 0,08 mm
