SKF NU 2234 ECML/C3 170x310x86 cylindrical roller bearing

Construction and design

The SKF NU 2234 ECML/C3 is a high performance cylindrical roller bearing designed for heavy industrial applications with very high radial loads.

The NU design features no flanges on the inner ring, allowing axial displacement between the shaft and housing. This enables compensation of thermal expansion and prevents internal stress.

The ECML version includes optimized internal geometry and a robust cage design, ensuring stable operation under heavy loads. The C3 radial clearance allows reliable performance in higher temperature conditions.
