NTN 6044 radial ball bearing for maintenance

This NTN 6044 single row radial ball bearing suits engineers and mechanics who need a direct replacement for worn units in electric-motor or gearbox assemblies. Its open design allows easy inspection and lubrication during scheduled service intervals. The 220 by 340 by 56 millimetre envelope matches the original housing without modification.

Open type simplifies relubrication tasks

Because the bearing ships without seals or shields, technicians can flush old grease and apply fresh lubricant without dismounting the unit from the shaft. This reduces downtime on production lines where continuous operation is required. Buyers who require sealed-for-life protection or integrated snap-ring retention should select a different variant.

Questions about this item

Does the open-type NTN 6044 need periodic relubrication?

Yes, the open design exposes the rolling elements, so scheduled grease replenishment is required to maintain the 220x340x56mm bearing's service life.

What limits continuous operation of this 6044 bearing first?

Without seals, contaminant ingress and lubricant loss become the primary constraints during sustained running, accelerating wear on the 56 mm wide raceways.
