Cylindrical Roller Bearings FAG NU2222 -E-XL-TVP2-C3

The FAG NU2222 -E-XL-TVP2-C3 cylindrical roller bearing, with a 110 mm bore, offers high radial load-carrying capacity as a separable idler bearing with a polyamide cage.

This single-row cylindrical roller bearing, NU2222 -E-XL-TVP2-C3, is primarily designed to withstand high radial loads. The line contact of the cylindrical rollers distributes the applied forces evenly across the raceways. In the NU design, the outer ring has two fixed flanges, whilst the flangeless inner ring remains removable from both sides. This allows the rolling bearing to compensate for axial displacement of the shaft during operation without any binding. With dimensions of 110x200x53 mm, it is suitable for heavy-duty industrial bearing arrangements subject to high radial loads.

What is the NU2222 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

Design engineers select this design for shaft mountings where operational length changes or manufacturing tolerances require unimpeded length compensation. It is primarily used in mountings subject to high radial loads that are designed as pure support bearings. The removable inner ring allows the inner and outer rings to be fitted separately, which facilitates installation and maintenance work on large shafts. As the bearing is of an open design, the lubricant is supplied directly via the housing structure.

What are the advantages of the polyamide cage and the C3 clearance?

The polyamide cage (TVP2) guides the rollers quietly and reduces the inertia masses in the rolling element set. The bearing is designed for a temperature range of –30 to +120 degrees Celsius. The increased C3 radial clearance compensates for operational heating and tight fits without causing the rolling elements to become stressed. The outer ring has no groove or lubrication bore and is manufactured to tolerance class P0/PN or ABEC 1.
