Cylindrical Roller Bearings FAG NU2224 -E-XL-M1A-C3

The FAG NU2224 -E-XL-M1A-C3 cylindrical roller bearing, with dimensions of 120 × 215 × 58 mm, is designed to accommodate high radial loads as a separable loose bearing.

The NU2224 -E-XL-M1A-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG, designed for demanding industrial applications. With a bore of 120 mm, an outer diameter of 215 mm and a width of 58 mm, this design withstands high radial loads. As an open idler bearing, it has no integrated seal. The inner ring can be removed from both sides, which facilitates the separate mounting of the inner and outer rings in housings and on shafts.

What is the NU2224 -E-XL-M1A-C3 cylindrical roller bearing suitable for?

This NU2224 -E-XL-M1A-C3 cylindrical roller bearing is primarily suitable for bearing arrangements subject to very high radial loads. In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the flangeless inner ring compensates for axial length changes in the shaft without restriction. As the bearing is designed for operating temperatures ranging from -30 to +150 degrees, it meets the thermal requirements of continuous industrial operation.

What is the function of the solid brass cage and the C3 clearance?

The solid brass cage, guided on the outside, guides the rolling elements precisely and withstands high accelerations and vibrations. At the same time, the slightly increased radial clearance (C3) ensures that sufficient operating clearance remains during operation. If operational heating or tight fits reduce the bearing clearance, the C3 design prevents excessive stresses. As the bearing is of open design and the outer ring has no lubrication bore, you can tailor the lubricant supply and the external housing seal directly to your design.
