Description

FAG 22205-E1-XL-C3 – Spherical Roller Bearing

The FAG 22205-E1-XL-C3 is a high-performance spherical roller bearing, designed to handle heavy radial loads and moderate axial loads in both directions while compensating for shaft misalignment and deflection. Manufactured by FAG, a globally recognized brand under the Schaeffler Group, this bearing is part of the E1 series — engineered to deliver enhanced load capacity, superior durability, and reduced friction under dynamic operating conditions. The C3 internal clearance further improves its suitability for high-speed and high-temperature environments.

Design and Performance

The 22205-E1-XL-C3 is part of FAG’s E1 (Enhanced Design) series, which features reinforced cage structures, optimized roller geometry, and larger rollers to improve load distribution and service life. The bearing includes two rows of spherical rollers, which self-align within the raceways, allowing it to absorb shaft misalignments, angular deflections, and housing deformations without causing performance loss or stress concentrations.

This self-aligning characteristic makes it ideal for applications where shaft bending or mounting errors are expected, ensuring smooth operation even under demanding conditions. It also makes it highly suitable for heavy-duty rotating machinery that operates under shock loads or continuous vibrations.

The C3 internal clearance refers to the greater-than-normal radial clearance between the inner and outer rings, allowing for thermal expansion of the shaft and high-speed operation without increasing internal stress. This makes it especially useful in applications with temperature variations or where high rotational speeds are critical.

Construction and Materials

The FAG 22205-E1-XL-C3 is manufactured using high-quality, heat-treated bearing steel, which provides excellent wear resistance, hardness, and dimensional stability under load. The rollers are symmetrical and guided within a precision-machined brass or steel cage, which maintains optimal spacing and minimizes friction during operation.

The raceways are spherically contoured, enabling the self-aligning feature and allowing the bearing to tolerate angular misalignments of several degrees without excessive friction or heat buildup. This helps extend the bearing’s service life and reduces maintenance frequency.

The bearing is not sealed, meaning it must be properly lubricated during installation and maintained according to the application’s duty cycle. It is compatible with both grease and oil lubrication systems, depending on speed, load, and temperature requirements.

Applications

Thanks to its robust construction, high load ratings, and misalignment tolerance, the FAG 22205-E1-XL-C3 is commonly used in:

• Gearboxes and transmissions

• Conveyor systems

• Pumps and compressors

• Fans and blowers

• Mining and construction equipment

• Paper and steel mills

• Agricultural and forestry machinery

It is especially suitable for heavy-duty applications with fluctuating loads and challenging environmental conditions, where precision alignment is difficult or impractical.

Installation and Compatibility

The bearing adheres to ISO standards, ensuring full interchangeability with equivalent models from other major manufacturers such as SKF, NSK, NTN, and Timken. Its compact dimensions (25x52x18 mm) and lightweight build (approx. 0.18 kg) make it easy to install, even in tight assemblies or retrofits.

Care must be taken during installation to ensure proper alignment, lubrication, and torque to avoid early wear. The bearing’s split-ring design allows for flexible mounting and dismounting without damaging surrounding components.
