ZIBOO NTN 21314 Spherical Roller Bearing
This new spherical roller bearing from ZIBOO carries the NTN 21314 designation and measures 70x150x35mm. It suits maintenance engineers and electricians who need a replacement rolling element for rotating equipment. The unit is supplied as a single component ready for press-fit installation.
Sustained-load behaviour
The spherical roller design distributes radial and axial forces across two rows of barrel-shaped rollers, reducing stress concentration during continuous operation. Self-alignment capability compensates for shaft deflection or housing misalignment that develops under long-running thermal cycles. This geometry maintains contact integrity where a single-row bearing would develop edge loading. Installers who require high-speed capability beyond the rating of this series should verify the limit before specifying it.
Highlights
- Spherical roller design handles heavy radial and axial loads
- 70 mm bore fits standard shaft sizes
- 150 mm outer diameter suits common housings
- 35 mm width provides robust load capacity

Questions about this item
How much heat does the NTN 21314 spherical roller bearing generate during continuous operation?
Heat output depends on load, speed and lubrication; the bearing itself has no fixed thermal rating.
What shaft and housing dimensions are required to install the 70x150x35mm bearing?
A 70 mm shaft and 150 mm housing bore with 35 mm width clearance are needed for proper fit.
