NTN 6411 open radial ball bearing 50x130x31mm

This single-row radial ball bearing carries the NTN 6411 designation and measures 50 millimetres bore by 130 millimetres outside diameter by 31 millimetres width. The open design leaves both sides exposed for easy lubrication access and inspection. It suits electricians and maintenance technicians who need a standard replacement bearing for motor shafts, gearboxes or conveyor rollers.

Not for sealed or shielded applications

Buyers who need contamination protection should choose a shielded or sealed variant instead. The open type also cannot retain pre-packed grease in high-speed or vertical-mount scenarios. Anyone requiring a different bore, width or load rating must select another part number.

Questions about this item

Should I pick the 50 mm bore, 130 mm outer diameter or 31 mm width version of the NTN 6411?

The NTN 6411 is a single size — 50 mm bore, 130 mm outer diameter and 31 mm width — so there is no alternative version to choose.

What does the 6411 designation tell me about load capacity once the bearing is installed?

The 6411 code identifies this single-row radial ball bearing’s boundary dimensions (50×130×31 mm) and open-type construction; actual load capacity depends on the shaft fit, housing tolerance and operating speed in your application.
