Cylindrical Roller Bearings FAG NU310 -E-XL-TVP2

The NU310 -E-XL-TVP2 cylindrical roller bearing from FAG, with dimensions of 50x110x27 mm, offers a precision free-running bearing design for high radial loads.

The NU310 -E-XL-TVP2 cylindrical roller bearing from FAG Rolling Bearings is designed as a single-row roller bearing with a cylindrical bore. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate high radial loads whilst maintaining a compact geometry. In the NU version, the outer ring has two fixed guide flanges, whilst the inner ring is manufactured without flanges. The bearing complies with the standard tolerance class P0/PN or ABEC 1 and is fitted with standard radial clearance.

How does the NU310 cylindrical roller bearing compensate for axial length changes?

In mechanical bearing arrangements, this design functions purely as a non-locating bearing when components need to compensate for operational axial length changes relative to the housing. As the inner ring can be freely removed from both sides, the shaft and bearing housing can slide relative to one another during thermal length expansion without causing axial stress in the rolling bearing. The open design without an integrated seal is designed for lubricated systems within a temperature range of -30 to +120 degrees.

What are the key features of this design and the polyamide cage?

The suffix TVP2 indicates a polyamide cage, which guides the rollers and contributes to smooth, low-friction operation. The low weight of the cage material keeps the centrifugal forces to a minimum. Furthermore, the separable design facilitates easy installation, as the inner and outer rings can be fitted separately onto the shaft and the housing bore. The outer ring’s outer surface is designed without a groove or lubrication hole.
