A developer and manufacturer of custom-made equipment for the steel fabrication industry uses sliding slewing ring bearings from igus® for rotary motion on an ultrasonic welding machine.
iglide® PRT slewing ring bearings facilitate movement on both the X and Y axis of the machine, which enables the welding gun to achieve numerous degrees of freedom. This means a variety of different welding jobs can be performed. The slewing ring bearings replaced a system of metal shafts and flange bearings that required time-consuming assembly and maintenance.
PRT slewing ring bearings do not require lubrication and so are unaffected by the welding dust produced by the machine and will not seize, unlike other bearing systems can. The unit comes as a ready-to-install solution, so the manufacturer saves both time and money during the design and assembly process.

The iglide PRT range uses low-friction polymer sliding elements in place of ball bearings. These sliding elements are made from an igus-developed, low-cost, high-performance polymer called iglide J, which is completely lubrication- and maintenance-free. iglide PRT slewing ring bearings are suitable for all environments; in particular, semiconductor and cleanroom applications, assembly lines, production facilities and robots.
PRT slewing ring bearings are an off-the-shelf, low-cost solution. All the housing components are made from aluminum (except style 02 – which has wear-resistant iglide J head rings) and all the surfaces parallel to the iglide J sliding elements are hard anodized with stainless steel fasteners. Stainless steel and geared versions are also available upon request.
