21308 E1 C3 FAG Spherical Roller Bearing 40x90x23

High Load Capacity for Industrial Applications

E1 Reinforced Design and C3 Internal Clearance

Technical Data and Mounting Options

Main Description:
The 21308 E1 C3 FAG 40x90x23 is a double-row spherical roller bearing designed for heavy-duty industrial applications where high radial and axial loads occur simultaneously. With dimensions 40x90x23 mm (inner diameter x outer diameter x width), this bearing is widely used in gearboxes, conveyor systems, vibrating equipment and heavy machinery.

Thanks to its spherical outer ring raceway, the bearing automatically compensates for shaft misalignment and housing deflection. This self-aligning capability significantly increases operational reliability in demanding environments. Compared to a standard ball bearing (łożysko kulkowe), a spherical roller bearing provides substantially higher load capacity and improved resistance to shock loads.

The E1 designation indicates an optimized internal design with increased dynamic load rating. The C3 internal clearance allows for safe operation at elevated temperatures, heavy loads or tight shaft fits. This combination ensures high durability, stable running behavior and extended service life under continuous industrial use.

The 21308 E1 C3 FAG can operate within a bearing housing (obudowa łożyskowa) or as part of a complete bearing unit (jednostka łożyskowa). Precision manufacturing guarantees even load distribution across both rows of rollers, minimizing vibration and reducing wear. It is a reliable solution for OEM manufacturers and maintenance departments seeking predictable performance in critical rotating assemblies.

FAQ

1. What does C3 clearance mean?
C3 indicates increased internal clearance compared to standard clearance, suitable for higher temperatures and heavy loads.

2. How does a spherical roller bearing differ from a ball bearing?
A spherical roller bearing supports higher radial and axial loads and compensates for misalignment, unlike a standard ball bearing.

3. What are the dimensions of 21308 E1 C3 FAG?
The dimensions are 40x90x23 mm (inner diameter x outer diameter x width).

4. In which applications is this bearing commonly used?
It is used in gearboxes, conveyors, crushers, vibrating screens and heavy industrial machinery.

5. Can it be installed in a bearing housing?
Yes, it can operate within a compatible bearing housing or as part of a complete bearing unit.
