NTN 6221 radial ball bearing for electricians
The ZIBOO NTN 6221 is a single row radial ball bearing built for electrician tooling. Its open design allows easy lubrication access and suits equipment where sealed units are not required. The bearing supports rotating shafts in motor housings, gearboxes or transmission assemblies common to trade workshops. Professionals choose this model for its standard dimensions and reliable rolling performance.
105x190x36mm open bearing fits standard housings
This bearing measures 105mm bore, 190mm outside diameter and 36mm width so it matches existing shaft and housing seats without modification. The open type needs external sealing or regular grease intervals to keep contaminants out. It frees up design space by eliminating integral seals while still handling radial loads in electric motor repair and industrial maintenance tasks.

Questions about this item
What is the 105 mm bore limit for the NTN 6221 bearing under sustained radial load?
The 105 mm bore defines the shaft fit; sustained radial capacity depends on the 6221 series dynamic rating, so verify the applied load against that rating before continuous operation.
How much heat does the open-type 6221 generate at 190 mm outer diameter during all-day running?
Open construction lets lubricant circulate and dissipates heat directly, so temperature rise stays low if the 36 mm width carries adequate grease or oil for the speed used.
