Key Features:
Spherical Outer Ring: The outer ring features a spherical raceway, allowing for self-alignment and compensating for shaft deflection or misalignment. This is crucial in applications where precise shaft alignment is difficult to achieve.
Cylindrical Rollers: The bearing utilizes large, robust cylindrical rollers, providing high load-carrying capacity in both radial and axial directions.
Cage: The cage guides the rollers, ensuring smooth and quiet operation while preventing contact between individual rollers.
CC/W33 Designation:
CC: Indicates a contact seal on both sides of the bearing, providing effective protection against contaminants such as dust, dirt, and moisture.
W33: Denotes a specific internal design or material variation within the 22236 series, offering potential enhancements in performance or durability.
Advantages:
High Load Capacity: Handles heavy radial and axial loads effectively.
Self-Aligning Capability: Accommodates shaft misalignment, reducing stress on the shaft and increasing bearing life.
Low Maintenance: Contact seals minimize the need for frequent relubrication.
Versatility: Suitable for a wide range of applications due to its robust design and adaptability.
Applications:
Heavy Industry: Widely used in applications such as mining equipment, construction machinery, and industrial presses where high loads and potential misalignment are common.
Wind Turbines: Employed in wind turbine gearboxes to accommodate the dynamic loads and vibrations experienced during operation.
Rolling Mills: Found in various components of rolling mills, where they withstand the high pressures and stresses involved in metal forming.
Material Handling Equipment: Used in conveyors, cranes, and other material handling systems that require reliable operation under demanding conditions.
