What is 249 Series Spherical Roller Bearing?
The 249 series spherical roller bearings are extra-large bore bearings designed for extreme radial loads in low-speed, heavy-duty industrial applications.
They are widely used in mining, cement, and metallurgical equipment where standard bearing series cannot meet load capacity requirements.
Compared with 240 and 231 series, the 249 series offers higher load capacity and larger bore sizes, making it suitable for ultra-heavy machinery.
249 Series Position in Heavy Duty Bearing Range
The 249 series belongs to the ultra-heavy-duty spherical roller bearing family, designed for applications requiring higher load capacity than 240 series and 231 series bearings.
