NTN 21320 Spherical Roller Bearing
The NTN 21320 is a spherical roller bearing built to 100x215x47mm dimensions. It suits technicians and maintenance teams who need a replacement component for heavy-duty rotating equipment. The bearing handles combined radial and axial loads in demanding industrial settings. It is supplied new and ready for installation.
Sustained-load behaviour
Under continuous operation the spherical roller design distributes stress across two rows of rollers, reducing peak contact pressure. The geometry tolerates shaft misalignment that occurs when housings flex over long runs. Heat generation stays manageable because the rolling elements maintain stable contact through the full rotation cycle. The bearing is not suited for applications requiring ultra-high precision or minimal friction at very high speeds.

Questions about this item
How much heat does the NTN 21320 bearing generate during continuous operation?
Heat output depends on the applied load, speed and lubrication; the bearing itself does not have a fixed thermal rating.
What shaft and housing tolerances are required to install the NTN 21320 bearing?
The bearing has a 100 mm bore and 215 mm outside diameter; correct fit tolerances must be selected from the NTN engineering catalogue for the specific application.
