Polymer pillow block ball bearings are up to 60% lighter and up to 40% more cost-effective than metal bearings. They also enable economically efficient operation. The bearings enable low-friction and hygienic dry operation. They are resistant to corrosion and media, optionally non-magnetic, electrically insulating and long-lasting. <br />igus® offers the xiros® pedestal-type ball bearings with two types of igubal® housing: an especially compact, rigid version whereby the stainless steel or glass balls roll directly in the housing. And a self-aligning version that compensates for misalignment.
