21309 E1 K TVPB FAG 45x100x25 spherical roller bearing

Main description

The 21309 E1 K TVPB FAG spherical roller bearing with dimensions 45x100x25 mm is a compact yet high performance bearing designed for applications requiring high load capacity, misalignment compensation and reliable operation under varying conditions.

This model belongs to the 213xx series of spherical roller bearings, commonly used in industrial machinery where both radial and axial loads must be supported. Its design allows it to carry heavy radial loads and axial loads in both directions while maintaining stability and long service life.

The E1 K TVPB design combines optimized internal geometry, a tapered bore and a lightweight polyamide cage, making this bearing efficient, easy to install and suitable for demanding environments.

Construction and design

The FAG 21309 E1 K TVPB is a double row spherical roller bearing with symmetrical rollers and a common spherical raceway in the outer ring.

The E1 designation indicates enhanced load capacity due to improved internal design. The K tapered bore allows mounting on adapter sleeves, increasing installation flexibility and simplifying assembly.

The TVPB polyamide cage reduces weight, lowers friction and ensures smooth and quiet operation, even at higher speeds.

Industrial applications

This spherical roller bearing is widely used in systems where misalignment and dynamic loads are present.

Typical applications include:
gearboxes and drive systems
industrial machinery and production equipment
conveyors and material handling systems
agricultural and construction machinery
fans and industrial ventilation systems

Within the spherical roller bearing category, the 21309 E1 K TVPB FAG is a versatile solution for medium to heavy duty applications.
