ZIBOO NTN 6038 Bearing for Industrial Use
The ZIBOO NTN 6038 is a single row radial ball bearing built for machinery that requires open-type lubrication access. It suits maintenance engineers and original-equipment assemblers who need a 190x290x46mm unit for electric-motor shafts, gearboxes or conveyor rollers. The open design allows direct oil or grease replenishment without seal removal.
Sustained Load Behaviour of Open Bearing
Under continuous rotation the open cages run cooler than sealed variants because churning losses are lower and fresh lubricant can enter freely. Steel balls and raceways maintain dimensional stability at the 46mm width when heat builds over long shifts. Contamination ingress is the limiting factor, so the bearing performs best in filtered or regularly serviced environments.
Highlights
- Open design simplifies lubrication and inspection
- Single row radial construction handles combined radial and axial loads

Questions about this item
How much noise and heat does the NTN 6038 generate during continuous all-day operation?
As an open-type radial ball bearing, the NTN 6038 produces minimal mechanical noise and heat under normal load; proper lubrication keeps both low during extended running.
What shaft diameter must my equipment have for the 190 mm bore of this bearing to fit?
The NTN 6038 requires a 190 mm shaft seat; the mating shaft must be machined to that diameter with the correct tolerance for a secure press fit.
