Cylindrical Roller Bearings FAG N309 -E-XL-TVP2

The FAG N309 -E-XL-TVP2 cylindrical roller bearing is a single-row idler bearing with a polyamide cage and main dimensions of 45 × 100 × 25 mm, designed for high radial loads.

This open cylindrical roller bearing, the N309 -E-XL-TVP2, is designed to accommodate high radial forces. Thanks to the line contact between the cylindrical rolling elements, the roller bearing offers high radial rigidity. The design as a non-locating bearing allows for axial displacement of the shaft directly within the bearing, thereby compensating for thermal length changes without constraint.

In which bearing arrangements does the N309 -E-XL-TVP2 cylindrical roller bearing prove its worth?

The N-type non-locating bearing design is suitable for bearing arrangements subject to purely radial loads, where the shaft is axially guided by a separate locating bearing. As the outer ring has no flange, the bearing does not accommodate any axial forces. Thanks to its open design, the component can be flexibly integrated into housing-side lubrication circuits using grease or oil.

What are the distinctive features of the N-type design and the polyamide cage?

In the N design, the inner ring has two fixed flanges, whilst the outer ring is flangeless and can be removed from both sides. This design facilitates assembly, as the inner and outer rings can be fitted separately. The polyamide cage is characterised by its smooth running properties and low noise levels, and is designed for operating temperatures ranging from –30 to +120 degrees. Together with the standard radial bearing clearance and tolerance class P0 (ABEC 1), the bearing unit is suitable for common fits in mechanical engineering.
