💡 What is a double-row roller bearing used for in sheave and pulley systems? A double-row roller bearing handles higher radial loads and keeps sheaves aligned under heavy duty. - Improves radial load capacity versus sealed ball bearing replacements, boosting uptime - Oil hole plus shields make maintenance easy and handy for hoists, conveyors and overhead pulleys - Not always interchangeable with linear slide unit bearings or ceramic options; consider ceramic for low-friction or high-temperature needs
