NTN 6334 open radial ball bearing

The ZIBOO NTN 6334 is a single-row radial ball bearing supplied in an open configuration. It suits maintenance engineers and machine builders who need a standard 170x360x72mm rolling element for electric-motor or gearbox shafts. The open design allows direct lubrication access during scheduled service intervals.

170x360x72mm capacity and limits

The bearing handles combined radial and moderate axial loads at typical industrial speeds within its 170mm bore 360mm outside diameter and 72mm width envelope. It runs out when contamination enters the open races or when lubrication intervals are extended beyond the grease life, making sealed alternatives necessary for dirty or hard-to-reach locations.

Questions about this item

Will the 170 mm bore of the NTN 6334 fit the existing shaft on my older motor?

The bearing has a 170 mm bore, 360 mm outside diameter and 72 mm width; measure your shaft and housing to confirm the same dimensions before installing.

How can I verify the NTN 6334 is running correctly after installation?

After fitting, rotate the shaft by hand — it should turn smoothly without binding or noise; then run the equipment at low speed and check for vibration or overheating at the bearing housing.
