ZIBOO NTN 2311K Self Aligning Ball Bearings

The ZIBOO NTN 2311K is a self aligning ball bearing supplied new for maintenance and repair tasks. It suits electricians and mechanics who need to replace worn bearings in motors, gearboxes or rotating equipment. The bearing accommodates angular misalignment between shaft and housing.

Bore diameter 55 mm outside diameter 120 mm width

The critical specification is the 55 mm bore, 120 mm outside diameter and 43 mm width, identified by the 2311K designation. These three dimensions determine whether the bearing fits the shaft and housing. Buyers needing a different bore size, width or load rating cannot use this part.

Questions about this item

How does the 55 mm bore size affect fitment on a shaft?

The 55 mm bore matches shafts of that diameter, allowing the bearing to seat directly without adapters.

What does the K suffix on the 2311K model indicate for mounting?

The K suffix denotes a tapered bore, so the bearing mounts on a tapered shaft or adapter sleeve for secure location.
