💡 What is a roller bearing used for in sheave and pulley systems? A roller bearing supports heavy radial loads and keeps pulley shafts running smooth, making it a handy option for demanding rotating equipment. - Provides strong radial load support for pulleys, sheaves, winches, and conveyor drums - Sealed design with oil holes allows scheduled relubrication to extend service life - Matches NAS metric series mounting patterns and can replace sealed ball bearing units in many setups - For lower friction or higher speed needs, consider ceramic-tipped or ceramic hybrid sealed ball bearing alternatives
