Cylindrical Roller Bearings FAG NU217 -E-XL-M1-C3

The FAG NU217 -E-XL-M1-C3 cylindrical roller bearing is a single-row idler bearing with a brass cage, C3 clearance and dimensions of 85 × 150 × 28 mm, designed for high radial loads.

The FAG NU217 -E-XL-M1-C3 cylindrical roller bearing is designed as a single-row radial roller bearing for demanding industrial applications. With a bore of 85 mm, an outer diameter of 150 mm and a width of 28 mm, this roller bearing can withstand high radial loads. In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring remains flangeless. This allows the inner ring to be removed from both sides, which simplifies the assembly of the separate bearing rings.

In which applications is the NU217 -E-XL-M1-C3 non-locating bearing used?

This non-locating bearing is primarily suitable for shaft mountings where thermally induced changes in length must be compensated for without restriction. Thanks to the inner ring, which can slide on both sides, the design compensates for axial displacement directly within the rolling element set. Typical applications are found in general mechanical engineering for bearing arrangements subject to high radial loads and operating temperatures ranging from -30 °C to +150 °C. The solid brass cage guides the cylindrical rollers precisely under dynamic loads.

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

This design combines a solid brass cage with the increased radial clearance C3. This clearance provides additional radial play, ensuring the bearing rolls smoothly even under operational heating or tight shaft fits. The brass cage absorbs high guiding forces and is suitable for demanding vibration loads. As the outer ring has no groove or lubrication bore and the component is of open design, the lubricant is supplied via the housing design.
