ZIBOO NTN 6028 Open Bearing
The ZIBOO NTN 6028 is a single row radial ball bearing with an open design. It measures 140mm inner diameter, 210mm outer diameter and 33mm width. This unit suits maintenance engineers and OEM assemblers who need a standard 6028 series bearing for electric motor or gearbox repairs.
Open Type Speed and Contamination Limits
The open construction allows higher rotational speeds because there is no seal drag, but it offers no barrier against dust or moisture. Lubricant can escape and contaminants can enter, so the bearing must run in a clean, sealed housing with a separate lubrication system. It is not suitable for exposed or dirty environments where sealed variants would survive longer.
Highlights
- Open design simplifies lubrication and inspection

Questions about this item
Should I choose the 140 mm bore or the 210 mm outer diameter for my shaft and housing?
The 140 mm bore fits the shaft and the 210 mm outer diameter fits the housing; both dimensions belong to the same 6028 bearing and must match your design.
What does the 33 mm width mean when the bearing is installed?
The 33 mm width is the axial space the 6028 occupies between the shaft shoulder and the housing face once pressed in.
