Cylindrical Roller Bearings FAG NJ204 -E-XL-TVP2

The FAG NJ204 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 20 × 47 × 14 mm, can accommodate high radial forces as well as unilateral axial loads.

The NJ204 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing manufactured by FAG with a bore of 20 mm, an outer diameter of 47 mm and a width of 14 mm. Designed as an open bearing, this component requires an external lubricant supply and a suitable housing seal. With its standard radial clearance and standardised tolerance class P0/PN (corresponding to ABEC 1), the design is suitable for a wide range of industrial applications. Rolling bearings in this series are used where rigid shaft guidance and the ability to withstand high radial loads are required.

What is the NJ204 -E-XL-TVP2 cylindrical roller bearing suitable for as a support bearing?

In the NJ design, the bearing serves as a support bearing. The outer ring has two fixed flanges, whilst the inner ring has one flange. This arrangement enables the bearing to accommodate axial forces from one direction, whilst allowing axial displacement in the opposite direction. This feature is utilised to compensate for thermal length changes in shafts without inducing stress. Furthermore, the inner ring can be removed from one side, which simplifies the separate assembly of both bearing rings.

What are the key features of the TVP2 design with a polyamide cage?

The integrated polyamide cage guides the rolling elements with minimal vibration and contributes to smooth running. The bearing is designed for a temperature range of -30 to +120 degrees. As this is an open bearing without a seal and without a groove or lubrication bore in the outer ring, lubrication must be provided via the housing design. The standard radial bearing clearance is suitable for common fit conditions. Design engineers also value this design for applications where low cage weight and guided roller movement are key considerations.
