Spherical Roller Bearing 23218 / 22318 / 22220 / 23220 – Heavy Load, Sealed Design for Mining, Vibrating Screen & Industrial Gearbox
Our spherical roller bearing series including BS2-2218-2CSK, 22318 EK, 24020 CC/W33, 23120-2CS2/VT143, 22220 EK and related models are designed for heavy-duty industrial equipment operating under high load, vibration, and dusty environments.
These bearings feature a self-aligning roller structure that helps compensate for shaft misalignment and reduces vibration during operation. Models with W33 lubrication groove improve grease distribution and heat dissipation, while sealed versions such as BS2-2218-2CSK and 24020-2CS2/VT143 provide additional protection against dust, moisture, and contamination.
Available in cylindrical bore and tapered bore designs, this bearing series supports easier installation and stable operation in continuous working conditions.
