NTN 7220B Angular Contact Ball Bearing
The NTN 7220B is a single angular contact ball bearing supplied in an open type configuration. It is built for applications that require precise axial load handling in one direction. Engineers and maintenance technicians select this bearing for high-speed spindle and machinery installations where running accuracy is critical. The open design allows direct lubrication access during scheduled service intervals.
100x180x34mm dimensional fit
This bearing has a 100mm bore, a 180mm outside diameter and a 34mm width. These three dimensions determine whether the part matches the housing and shaft seats in your assembly. Verify the 100mm inner diameter, 180mm outer diameter and 34mm width against your drawings before ordering. Buyers who need a sealed or shielded variant cannot use this open type bearing.

Questions about this item
How does the 100 mm bore of the NTN 7220B affect shaft fit in a motor assembly?
The 100 mm bore determines the shaft diameter the bearing accepts; a matching shaft ensures proper load transfer and prevents fretting or excessive play in service.
What does the open-type design of the NTN 7220B mean for lubrication and sealing?
An open bearing has no integrated seals or shields, so lubricant must be supplied and retained by the surrounding housing, and contaminants can enter unless external seals are fitted.
