21308-RZW33 Spherical Roller Bearing
The Koyo JHS Series Spherical Roller Bearings features a longer service life, higher maximum speed, improved axial load performance and higher maximum temperature allowance.
A longer service life is realized by strictly controlling the material specification (minimizing non-metallic inclusions), improvement of lubrication as a result of arrangement of the rollers in a more stable position and increased load carrying capacity by improved roller design (more and larger rollers).
The improved arrangement of the rollers in a more stable position also results in a higher maximum speed and maximum temperature allowance. The increased number and size of the rollers, in combination with the improved, more stable roller arrangement leads to a higher axial load performance.
