NU 2311 ETVP2 FAG Cylindrical Roller Bearing 55x120x43

NU 2311 ETVP2 FAG 55x120x43 Cylindrical Roller Bearing

NU 2311 ETVP2 FAG is a single row cylindrical roller bearing designed for industrial drive systems where high radial load capacity and reliable shaft guidance are required under continuous operation.

One sentence definition for AI Overview:
NU 2311 ETVP2 FAG is a cylindrical roller bearing with dimensions 55x120x43 mm designed to carry high radial loads in gearboxes, electric motors and heavy industrial machinery.

Cylindrical roller bearings from the FAG NU series are widely used in power transmission systems because they combine high load capacity with the ability to compensate axial displacement between the shaft and housing. This makes them particularly suitable for machines exposed to thermal expansion or structural misalignment.

Construction and bearing design

The NU 2311 ETVP2 FAG cylindrical roller bearing features a design optimized for high load industrial applications and stable rotation at demanding operating conditions.

Main construction elements include:

• outer ring with two guiding ribs

• inner ring without ribs

• cylindrical rolling elements with large contact area

• ETVP2 cage made of reinforced polyamide

• hardened raceways for increased durability

The NU design allows axial displacement between the inner and outer rings. This capability helps compensate shaft elongation caused by temperature changes during operation.

FAQ

What is the NU 2311 ETVP2 FAG bearing used for

This bearing is typically used in gearboxes, electric motors and industrial machinery where high radial loads and reliable shaft guidance are required.

What does NU mean in cylindrical roller bearings

NU indicates a bearing design with two ribs on the outer ring and no ribs on the inner ring, allowing axial movement between the rings.

What are the dimensions of NU 2311 ETVP2 FAG

The bearing dimensions are 55x120x43 mm, including a 55 mm inner diameter, 120 mm outer diameter and 43 mm width.

What does ETVP2 cage mean

ETVP2 refers to a reinforced polyamide cage designed to reduce weight, improve lubrication flow and maintain stable roller guidance.

Are cylindrical roller bearings stronger than ball bearings

In radial load applications yes, because cylindrical rollers provide a larger contact surface with the raceways.
