NTN 6340 Open Radial Bearing
The ZIBOO NTN 6340 is a single row radial ball bearing built to the 6340 series dimensions of 200x420x80mm. Its open design allows direct lubrication access and suits applications where external seals are already present. Maintenance teams and machinery rebuilders use it to replace worn units in electric motors, gearboxes and industrial shafts. The component arrives new and ready for press fitting onto a 200mm shaft.
Sustained Load Behaviour
Under continuous rotation the open cages run cooler than sealed equivalents because fresh grease can be introduced without disassembly. The single row geometry handles combined radial and axial forces but reaches its dynamic limit earlier than double row alternatives. Builders needing higher axial capacity or integral contamination protection should select a different bearing style.

Questions about this item
How much heat does the NTN 6340 bearing generate during continuous operation?
The open design allows lubricant circulation and airflow, which helps dissipate heat generated by the 200 mm inner diameter and 420 mm outer diameter rolling elements during all-day running.
What shaft and housing dimensions must I already have for the 6340 bearing to fit?
You need a 200 mm shaft seat and a 420 mm housing bore with an 80 mm width clearance to match the bearing's 200x420x80 mm envelope.
