22210EK/C3 Spherical Roller Bearing 50x90x23mm Self-aligning Double-row Bearings

Product Overview：

In heavy industrial applications, equipment is subjected to punishing loads, shaft deflection, and thermal expansion that would quickly destroy standard bearings. The 22210EK/C3 spherical roller bearing is purpose-built to thrive in these extreme environments. With precise dimensions of 50 mm bore, 90 mm outer diameter, and 23 mm width, this double-row bearing delivers exceptional load-carrying capacity while accommodating significant shaft misalignment—all without compromising performance or service life.

Core Performance Advantages:

• Exceptional Load-Carrying Capacity
  With a dynamic load rating of up to 107 kN and a static load rating of 108 kN, the 22210EK/C3 delivers outstanding load capacity for its compact 50×90×23 mm envelope. The double-row design and E-type optimized internal geometry ensure maximum load distribution across all rolling elements.

• Superior Misalignment Accommodation
  The self-aligning design tolerates angular misalignment between the shaft and housing without increasing friction or reducing bearing life. This is critical in applications where shaft deflection, housing deformation, or installation inaccuracies are unavoidable, such as long conveyor shafts, gearbox output shafts, and heavy machinery.

• Easy Mounting with Tapered Bore
  The 1:12 tapered bore allows straightforward mounting on cylindrical shafts using standard adapter sleeves. This simplifies installation, reduces downtime, and enables precise clearance adjustment during mounting. The tapered bore also facilitates removal using withdrawal sleeves, simplifying maintenance and replacement.

• High-Speed Capability
  With a limiting speed of 9,500 RPM and a reference speed of 7,000 RPM, the 22210EK/C3 is suitable for a wide range of rotational speeds. The C3 clearance ensures smooth operation at higher speeds by accommodating thermal expansion and preventing excessive preload.

• Relubrication-Friendly Design
  The annular groove and three lubrication holes in the outer ring facilitate efficient relubrication, ensuring consistent lubrication delivery to the rolling elements and extending service life.

Industrial Applications:

The 22210EK/C3 spherical roller bearing is a versatile component trusted across numerous heavy industries:

• Mining and Aggregate Equipment
  Crushers, vibratory screens, conveyors, and processing equipment benefit from the bearing’s high load capacity, shock resistance, and misalignment tolerance.

• Material Handling and Conveyors
  Belt conveyors, screw conveyors, bucket elevators, and bulk material handling systems require bearings that can handle heavy radial loads and accommodate shaft deflection over long spans.

• Industrial Gearboxes and Reducers
  Gearbox output shafts, planetary gear sets, and speed reducers use the 22210EK/C3 for its combined radial and axial load capacity.

• Construction and Engineering Machinery
  Excavators, loaders, bulldozers, and heavy equipment rely on the bearing’s durability and ability to withstand shock loads and misalignment.

• Printing and Paper Machinery
  Printing presses and paper processing equipment benefit from the bearing’s precision and reliability.
• Steel and Metallurgical Equipment
  Rolling mills, continuous casting equipment, and heavy industrial machinery require bearings that can withstand extreme loads and temperatures.
• Wind Turbines
  Pitch and yaw systems in wind turbines use spherical roller bearings for their ability to accommodate misalignment and handle heavy loads.
• Marine and Offshore Equipment
  Deck machinery, propulsion systems, and offshore platform equipment benefit from the bearing’s corrosion resistance and durability.
