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.
Highlights
- Open design simplifies lubrication access
- Single row construction handles combined radial and axial loads
- 140 mm bore fits standard shaft dimensions
- 18 mm width suits compact housing requirements

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.
