FAG 22210 E1 C4 50x90x23 — spherical roller bearing

Applications

The FAG 22210 E1 C4 bearing is widely used in heavy-duty industrial equipment, gearboxes, shafts, conveyors, crushers, mills, and rotating machinery where high radial loads, shaft misalignments, or structural deflections occur. Its self-aligning design makes it suitable for applications with possible shaft deflection, housing deformation, or assembly tolerances — common in mining, cement, aggregates, or heavy machinery.

Key Advantages

• High load capacity: With a dynamic radial load rating of ~109 kN and static rating ~107 kN, the bearing can sustain heavy radial loads and shock loads, ensuring durability under demanding operational conditions.

• Self-aligning, misalignment tolerant: The spherical outer raceway allows compensation for shaft deflection or misaligned housings with minimal increase in friction or temperature — a major advantage in real-world industrial installations.

• Radial internal clearance C4: The increased internal clearance supports operation under variable thermal expansion, heavy loads or fluctuating temperatures — preventing excessive preload and reducing risk of overheating or premature wear.

• Robust construction: Steel cage and high-quality bearing steel ensure long service life, resistance to fatigue, impact loads, and vibrations — ideal for harsh industrial environments.

Technical Data

Description

The FAG 22210 E1 C4 is a robust spherical roller bearing engineered for heavy-duty industrial applications requiring both high radial load capacity and tolerance for shaft misalignment. With a 50 mm bore and 90 mm outer diameter, and width of 23 mm, this bearing combines compact dimensions with exceptional load-bearing capabilities. Its dual-row barrel roller configuration and spherical outer raceway make it self-aligning — an essential feature for installations where slight shaft deflections or misalignments are inevitable.

The C4 radial internal clearance ensures the bearing maintains reliable performance under conditions of thermal expansion, heavy loads, or variable operation regimes. Thanks to its steel cage and premium bearing-grade steel construction, the 22210 E1 C4 withstands vibration, shock loads and extended operating cycles, offering long service life and reduced total cost of ownership compared with standard bearings.

This bearing is ideal for gearboxes, industrial shafts, conveyor rollers, crushers, mills, and heavy machinery drives — wherever radial loads are high and structural or assembly tolerances demand a bearing capable of self-alignment and stable performance. Its load ratings and speed limits make it versatile across a wide range of industrial equipment.

FAQ

Q: What does “C4 clearance” mean, and why is it important?
A: C4 denotes increased radial internal clearance compared to standard bearings. It provides additional space to accommodate thermal expansion, shaft deformation, or misalignment without inducing excessive preload — thus improving bearing lifespan under demanding conditions.

Q: Can FAG 22210 E1 C4 handle shaft misalignment or deflection?
A: Yes — as a spherical roller bearing, it features a spherical outer raceway that allows self-alignment. This design tolerates angular errors between shaft and housing axes while maintaining low friction and stable operation.

Q: What kind of loads and speeds is this bearing suited for?
A: The bearing supports heavy radial loads (dynamic ~109 kN, static ~107 kN) and occasional shock or impact loads. Limiting speed is about 9,500 rpm, making it suitable for medium-speed industrial applications.

Q: Is this bearing suitable for harsh industrial environments (vibrations, shock, dust)?
A: Yes — robust steel construction and double-row barrel rollers ensure high fatigue resistance, wear resistance, and durability under vibration, shock loads, and variable operating conditions.

Q: Are there any special maintenance or lubrication requirements?
A: Standard lubrication with grease or oil appropriate for the operating environment is sufficient. The robust design tolerates common industrial conditions. For heavy-duty or high-load applications, periodic relubrication according to machinery guidelines is recommended.
