NTN 6818 radial bearing for electricians
The ZIBOO NTN 6818 is a single-row radial ball bearing built for electrician tooling. Its open-type design suits maintenance tasks where sealed units are not required. The 90 mm bore and 115 mm outer diameter fit standard shaft sizes used in motor and gearbox repairs.
Open design runs with minimal friction
Without seals the bearing generates low drag and stays quiet during normal rotation. Heat build-up is limited because lubricant can circulate freely. The 13 mm width keeps the assembly compact inside tight tool housings. Power draw from the driving motor is not increased by the bearing itself.

Questions about this item
How do I press the NTN 6818 bearing onto a 90 mm shaft without damaging the balls?
Apply force only to the inner ring using a sleeve that matches the 90 mm bore; never hammer the outer ring or the cage.
What tells me the open-type NTN 6818 needs relubrication or replacement?
Rising noise, detectable radial play at the 115 mm outer diameter, or overheating during operation signal that the grease is exhausted or the raceways are worn.
