ZIBOO NTN 6820 Single Row Radial Ball Bearing Open Type 100x125x13mm

NTN 6820 radial ball bearing for electricians

The NTN 6820 is a single row radial ball bearing built for electrician tooling and maintenance tasks. Its open type design suits applications where external sealing is handled separately or where lubricant access is required. Electricians and maintenance technicians working on motor shafts or gear assemblies will find the 100x125x13mm dimensions match standard fits.

Open type construction allows direct lubrication

The open configuration means grease or oil can be applied without disassembly, simplifying routine upkeep in workshop environments. Absence of integral seals reduces drag at speed but requires the surrounding assembly to exclude contaminants. The 100 mm bore, 125 mm outside diameter and 13 mm width determine housing and shaft tolerances, so installers must verify mating parts before fitting. Builders needing sealed or shielded variants should select a different bearing style.
