VL0241 insulated cylindrical roller bearings combine high radial load capacity with electrical insulation through an Al2O3 coating on the outer ring. Insulation resistance exceeds 100 MΩ at 1000 VDC, effectively blocking shaft currents while maintaining the robust load-handling characteristics required in traction motor gearboxes and heavy industrial gear units.
