SKF 22224 EK/C3 Tapered 120 mm ID Roller Bearing, 215 mm OD

This roller bearing is a double-row tapered roller component designed for rotating assemblies where axial and radial load management is required. It is supplied with a tapered bore and an open-end configuration to facilitate mounting and alignment in mechanical and electrical systems. The bearing is manufactured from steel and uses a sheet-metal cage to retain the rolling elements, making it suitable for demanding industrial installations.

• High dynamic capacity delivers 652 kN of operational load support
• Robust static capability provides 780 kN for stationary loads
• C3 internal clearance permits thermal expansion under load
• Capable of continuous operation up to 3,800 r/min
• Two-row tapered design controls combined axial and radial forces
• Sheet-metal cage reduces component mass while maintaining guidance

• Suitable for heavy-duty gearbox shafts in automation lines
• Ideal for axles in industrial drives requiring high load capacity
• Used for spindle supports in electrical motor assemblies
• Can be used for thrust and radial support in mechanical presses

The rollers and raceways are steel, with two rows of tapered rollers designed to share combined loads across the races.

The open end allows direct access for axial adjustment and simplifies fitting with tapered adaptors or matched housings.

A sheet-metal cage is employed to retain rollers and ensure consistent spacing while offering reduced inertia for rotational stability.

It is provided with increased internal clearance (C3), which accommodates thermal growth and helps maintain preload under elevated temperatures.
