Double Row Cylindrical Roller Bearings NNU 4152 M/W33

The NNU 4152 M/W33 is a double-row cylindrical roller bearing with a 260mm bore and 440mm outer diameter, designed for heavy-duty applications. It handles combined loads with a dynamic radial capacity of 495,000 lbf and spins smoothly at up to 2000 RPM.

Made from high-quality materials, this bearing features a W33 lubrication groove for easy greasing or oiling. Its sturdy construction ensures reliable performance in temperatures ranging from -30°C to 110°C.

The bearing’s chamfered edges (4mm on both rings) simplify installation, while its 5.1mm axial displacement tolerance accommodates slight misalignments. It’s interchangeable with SKF models, making replacements straightforward.

Ideal for industrial machinery like gearboxes or heavy presses, this RoHS and REACH-compliant bearing balances durability with ease of maintenance. Its 180mm width provides stability under high radial loads.
