xiros® polymer ball bearings enable dry running where corrosion or contamination rule out metal designs. The catalog details materials for rings and cages, and compares friction, chemical resistance and allowable speed.
Dimensional tables are paired with load ratings and temperature windows, with notes on shaft/housing fits to control noise and life.
Applications range from packaging rollers to laboratory devices, where grease‑free operation is a must.
Handling and storage guidance helps preserve dimensional stability before assembly.
