NTN 6321 single-row radial bearing
The NTN 6321 is a single-row radial ball bearing supplied in an open configuration. It is intended for technicians and maintenance teams who need a replacement rolling element for electric-motor shafts, gearboxes or similar rotating equipment.
Open design allows direct lubrication access
The open-type construction means lubricant can be applied or inspected without removing seals, simplifying routine maintenance on accessible shafts. With a 105 mm bore, 225 mm outside diameter and 49 mm width, the bearing fits housings machined to those dimensions, but it offers no integrated sealing against dust or moisture.
