NTN 6828 Radial Ball Bearing

The ZIBOO NTN 6828 is a single-row radial ball bearing designed for mechanical assemblies that require low-friction rotation. Its open construction suits maintenance scenarios where lubrication access or inspection is needed. Electricians and technicians use it in motor rebuilds, pulley systems, and custom rigs where a compact, standardised bearing fits the shaft and housing.

140x175x18mm capacity and limits

The bearing handles radial loads on a 140mm shaft within a 175mm housing, with an 18mm width that fits standard grooves. It runs out when axial thrust exceeds the single-row design or when contaminants enter the open races, making sealed alternatives necessary for dirty environments. High-speed or heavy combined loads also exceed its practical envelope.

Questions about this item

Will the 140 mm bore of the NTN 6828 fit the existing shaft on my older motor?

The bearing has a 140 mm inner diameter, so it will slide onto any shaft machined to that size regardless of the motor's age.

How can I confirm the NTN 6828 is running correctly once installed?

After mounting, rotate the shaft by hand; it should turn smoothly with no grinding, and the 18 mm width should sit flush against the housing shoulder.
